  121. # dpi aware: Set this option (on by default) to indicate to your OS that DOSBox is DPI aware.
  122. # If it is not set, Windows Vista/7/8/10 and higher may upscale the DOSBox window
  123. # on higher resolution monitors which is probably not what you want.
  124. # keyboard hook: Use keyboard hook (currently only on Windows) to catch special keys and synchronize the keyboard LEDs with the host
  125. # weitek: If set, emulate the Weitek coprocessor. This option only has effect if cputype=386 or cputype=486.
  126. # bochs debug port e9: If set, emulate Bochs debug port E9h. ASCII text written to this I/O port is assumed to be debug output, and logged.
  127. # machine: The type of machine DOSBox tries to emulate.
  128. # Possible values: hercules, cga, cga_mono, cga_rgb, cga_composite, cga_composite2, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe, amstrad, pc98, pc9801, pc9821.
  129. # vmemdelay: VGA Memory I/O delay in nanoseconds. Set to -1 to use default, 0 to disable.
  130. # Default off. Enable this option (-1 or nonzero) if you are running a game or
  131. # demo that needs slower VGA memory (like that of older ISA hardware) to work properly.
  132. # If your game is not sensitive to VGA RAM I/O speed, then turning on this option
  133. # will do nothing but cause a significant drop in frame rate which is probably not
  134. # what you want. Recommended values -1, 0 to 2000.
  135. # vmemsize: Amount of video memory in megabytes.
  136. # The maximum resolution and color depth the svga_s3 will be able to display
  137. # is determined by this value.
  138. # 0: 512k (800x600 at 256 colors)

  140. # 2: 1600x1200 at 256 colors or 1024x768 at 64k colors or 640x480 at 16M colors
  141. # 4: 1600x1200 at 64k colors or 1024x768 at 16M colors
  142. # 8: up to 1600x1200 at 16M colors
  143. # For build engine games, use more memory than in the list above so it can
  144. # use triple buffering and thus won't flicker.
  145. #
  146. # vmemsizekb: Amount of video memory in kilobytes, in addition to vmemsize
  147. # captures: Directory where things like wave, midi, screenshot get captured.
  148. # capture chroma format: Chroma format to use when capturing to H.264. 'auto' picks the best quality option.
  149. # 4:4:4 Chroma is at full resolution. This provides the best quality, however not widely supported by editing software.
  150. # 4:2:2 Chroma is at half horizontal resolution.
  151. # 4:2:0 Chroma is at quarter resolution, which may cause minor color smearing.
  152. # However, this chroma format is most likely to be compatible with video editing software.
  153. # Possible values: auto, 4:4:4, 4:2:2, 4:2:0.
  154. # capture format: Capture format to use when capturing video. The availability of the format depends on how DOSBox-X was compiled.
  155. # default Use compiled-in default (avi-zmbv)
  156. # avi-zmbv Use DOSBox-style AVI + ZMBV codec with PCM audio
  157. # mpegts-h264 Use MPEG transport stream + H.264 + AAC audio. Resolution & refresh rate changes can be contained
  158. # within one file with this choice, however not all software can support mid-stream format changes.
  159. # Possible values: default, avi-zmbv, mpegts-h264.
  160. # mainline compatible mapping: If set, arrange private areas, UMBs, and DOS kernel structures by default in the same way the mainline branch would do it.
  161. # If cleared, these areas are allocated dynamically which may improve available memory and emulation accuracy.
  162. # If your DOS game breaks under DOSBox-X but works with mainline DOSBox setting this option may help.
  163. # mainline compatible bios mapping: If set, arrange the BIOS area in the same way that the mainline branch would do it.
  164. # If cleared, these areas are allocated dynamically which may improve available memory and emulation accuracy.
  165. # If your DOS game breaks under DOSBox-X but works with mainline DOSBox setting this option may help.
  166. # adapter rom is ram: Map adapter ROM as RAM (mainline DOSBox 0.74 behavior). When clear, unused adapter ROM is mapped out
  167. # shell environment size: Size of the initial DOSBox shell environment block, in bytes. This does not affect the environment block of sub-processes spawned from the shell.
  168. # This option has no effect unless dynamic kernel allocation is enabled.
  169. # private area size: Set DOSBox-X private memory area size. This area contains private memory structures used by the DOS kernel.
  170. # It is discarded when you boot into another OS. Mainline DOSBox uses 32KB. Testing shows that it is possible
  171. # to run DOSBox with as little as 4KB. If DOSBox-X aborts with error "not enough memory for internal tables"
  172. # then you need to increase this value.
  173. # a20: A20 gate emulation mode.
  174. # The on/off/on_fake/off_fake options are intended for testing and debugging DOS development,
  175. # or to emulate obscure hardware, or to work around potential extended memory problems with DOS programs.
  176. # on_fake/off_fake are intended to test whether a program carries out a memory test to ensure the A20
  177. # gate is set as intended (as HIMEM.SYS does). If it goes by the gate bit alone, it WILL crash.
  178. # This parameter is also changeable from the builtin A20GATE command.
  179. # fast Emulate A20 gating by remapping the first 64KB @ 1MB boundary (fast, mainline DOSBox behavior)
  180. # mask Emulate A20 gating by masking memory I/O address (accurate)
  181. # off Lock A20 gate off (Software/OS cannot enable A20)
  182. # on Lock A20 gate on (Software/OS cannot disable A20)
  183. # off_fake Lock A20 gate off but allow bit to toggle (hope your DOS game tests the HMA!)
  184. # on_fake Lock A20 gate on but allow bit to toggle
  185. # turn off a20 gate on boot: If enabled, A20 gate is switched off when booting a guest OS.
  186. # Enabled by default. Recommended for MS-DOS when HIMEM.SYS is not installed in the guest OS.
  187. # If disabled, and MS-DOS does not load HIMEM.SYS, programs and features that rely on the 1MB wraparound will fail.
  188. # isa bus clock: ISA BCLK frequency.
  189. # WARNING: In future revisions, PCI/motherboard chipset emulation will allow the guest OS/program to alter this value at runtime.
  190. # std8.3 8.333MHz (typical 386-class or higher)
  191. # std8 8MHz
  192. # std6 6MHz
  193. # std4.77 4.77MHz (precisely 1/3 x 14.31818MHz). Bus frequency of older PC/XT systems.
  194. # oc10 10MHz
  195. # oc12 12MHz
  196. # oc15 15MHz
  197. # oc16 16MHz
  198. # <integer or float> Any integer or floating point value will be used as the clock frequency in Hz
  199. # <integer/integer ratio> If a ratio is given (num/den), the ratio will be used as the clock frequency
  200. # pci bus clock: PCI bus frequency.
  201. # WARNING: In future revisions, PCI/motherboard chipset emulation will allow the guest OS/program to alter this value at runtime.
  202. # std33.3 33.333MHz (very common setting on motherboards)
  203. # std30 30MHz (some older mid-1990's Pentium systems)
  204. # std25 25MHz
  205. # <integer or float> Any integer or floating point value will be used as the clock frequency in Hz
  206. # <integer/integer ratio> If a ratio is given (num/den), the ratio will be used as the clock frequency
  207. # call binary on reset: If set, this is the path of a binary blob to load into the ROM BIOS area and execute immediately after CPU reset.
  208. # It will be executed before the BIOS POST routine, only ONCE. The binary blob is expected either to IRET or to
  209. # jump directly to F000:FFF0 to return control to the BIOS.
  210. # This can be used for x86 assembly language experiments and automated testing against the CPU emulation.
  211. # call binary on boot: If set, this is the path of a binary blob to load into the ROM BIOS area and execute immediately before booting the DOS system.
  212. # This can be used for x86 assembly language experiments and automated testing against the CPU emulation.
  213. # rom bios allocation max: Maximum size (top down from 1MB) allowed for ROM BIOS dynamic allocation in KB
  214. # rom bios minimum size: Once ROM BIOS layout is finalized, trim total region down to a minimum amount in KB
  215. # irq delay ns: IRQ delay in nanoseconds. Set to -1 to use default, 0 to disable.
  216. # This is a more precise version of the irqdelay= setting.
  217. # There are some old DOS games and demos that have race conditions with IRQs that need a nonzero value here to work properly.
  218. # iodelay: I/O delay in nanoseconds for I/O port access. Set to -1 to use default, 0 to disable.
  219. # A value of 1000 (1us) is recommended for ISA bus type delays. If your game
  220. # or demo is not sensitive to I/O port and ISA bus timing, you can turn this option off
  221. # (set to 0) to increase game performance.
  222. # iodelay16: I/O delay for 16-bit transfers. -1 to use default, 0 to disable.
  223. # iodelay32: I/O delay for 32-bit transfers. -1 to use default, 0 to disable.
  224. # acpi: ACPI emulation, and what version of the specification to follow.
  225. # WARNING: This option is very experimental at this time and should not be enabled unless you're willing to accept the consequences.
  226. # Intended for use with ACPI-aware OSes including Linux and Windows 98/ME. This option will also slightly reduce available
  227. # system memory to make room for the ACPI tables, just as real BIOSes do, and reserve an IRQ for ACPI functions.
  228. # Possible values: off, 1.0, 1.0b, 2.0, 2.0a, 2.0b, 2.0c, 3.0, 3.0a, 3.0b, 4.0, 4.0a, 5.0, 5.0a, 6.0.
  229. # acpi rsd ptr location: Where to store the Root System Description Pointer structure. You can have it stored in the ROM BIOS area, or the Extended Bios Data Area.
  230. # Possible values: auto, bios, ebda.
  231. # acpi sci irq: IRQ to assign as ACPI system control interrupt. set to -1 to automatically assign.
  232. # acpi iobase: I/O port base for the ACPI device Power Management registers. Set to 0 for automatic assignment.
  233. # acpi reserved size: Amount of memory at top to reserve for ACPI structures and tables. Set to 0 for automatic assignment.
  234. # memsize: Amount of memory DOSBox has in megabytes.
  235. # This value is best left at its default to avoid problems with some games,
  236. # though few games might require a higher value.
  237. # There is generally no speed advantage when raising this value.
  238. # Programs that use 286 protected mode like Windows 3.0 in Standard Mode may crash with more than 15MB.
  239. # memsizekb: Amount of memory DOSBox has in kilobytes.
  240. # This value should normally be set to 0.
  241. # If nonzero, it is added to the memsize parameter.
  242. # Finer grained control of total memory may be useful in
  243. # emulating ancient DOS machines with less than 640KB of
  244. # RAM or early 386 systems with odd extended memory sizes.
  245. # dos mem limit: Limit DOS conventional memory to this amount. Does not affect extended memory.
  246. # Setting this option to a value in the range 636-639 can be used to simulate modern BIOSes
  247. # that maintain an EBDA (Extended BIOS Data Area) at the top of conventional memory.
  248. # You may also play with this option for diagnostic purposes or to stress test DOS programs in limited memory setups.
  249. #
  250. # A few DOS games & demos require this option to be set:
  251. # Majic 12 "Show": If UMBs are enabled, set this option to 639 to avoid MCB chain corruption error.
  252. # isa memory hole at 512kb: If set, emulate an ISA memory hole at the 512KB to 640KB area (0x80000-0x9FFFF).
  253. # memalias: Memory aliasing emulation, in number of valid address bits.
  254. # . Many 386/486 class motherboards and processors prior to 1995
  255. # suffered from memory aliasing for various technical reasons. If the software you are
  256. # trying to run assumes aliasing, or otherwise plays cheap tricks with paging,
  257. # enabling this option can help. Note that enabling this option can cause slight performance degredation. Set to 0 to disable.
  258. # Recommended values when enabled:
  259. # 24: 16MB aliasing. Common on 386SX systems (CPU had 24 external address bits)
  260. # or 386DX and 486 systems where the CPU communicated directly with the ISA bus (A24-A31 tied off)
  261. # 26: 64MB aliasing. Some 486s had only 26 external address bits, some motherboards tied off A26-A31
  262. # pc-98 fm board: In PC-98 mode, selects the FM music board to emulate.
  263. # Possible values: auto, off, false, board26k, board86, board86c.
  264. # pc-98 fm board irq: If set, helps to determine the IRQ of the FM board. A setting of zero means to auto-determine the IRQ.
  265. # pc-98 fm board io port: If set, helps to determine the base I/O port of the FM board. A setting of zero means to auto-determine the port number.
  266. # pc-98 buffer page flip: If set, the game's request to page flip will be delayed to vertical retrace, which can eliminate tearline artifacts.
  267. # Note that this is NOT the behavior of actual hardware. This option is provided for the user's preference.
  268. # pc-98 enable 16-color: Allow 16-color graphics mode if set, disable if not set
  269. # pc-98 enable grcg: Allow GRCG graphics functions if set, disable if not set
  270. # pc-98 enable egc: Allow EGC graphics functions if set, disable if not set
  271. # pc-98 start gdc at 5mhz: Start GDC at 5MHz if set, 2.5MHz if clear. May be required for some games.
  272. # pc-98 allow scanline effect: If set, PC-98 emulation will allow the DOS application to enable the 'scanline effect'
  273. # in 200-line graphics modes upconverted to 400-line raster display. When enabled, odd
  274. # numbered scanlines are blanked instead of doubled
  275. # pc-98 video mode: Specify the preferred PC-98 video mode.
  276. # Valid values are 15, 24, or 31 for each specific horizontal refresh rate on the platform.
  277. # 24khz is default and best supported at this time.
  278. # 15khz is not implemented at this time.
  279. # 31khz is experimental at this time.
  280. # Possible values: , 24khz, 31khz, 15khz.
  281. # pc-98 timer master frequency: 8254 timer clock frequency (NEC PC-98). Depending on the CPU frequency the clock frequency is one of two common values.
  282. # If your setting is neither of the below the closest appropriate value will be chosen.
  283. # This setting affects the master clock rate that DOS applications must divide down from to program the timer
  284. # at the correct rate, which affects timer interrupt, PC speaker, and the COM1 RS-232C serial port baud rate.
  285. # 8MHz is treated as an alias for 4MHz and 10MHz is treated as an alias for 5MHz.
  286. # 0: Use default (auto)
  287. # 4: 1.996MHz (as if 4MHz or multiple thereof CPU clock)
  288. # 5: 2.457MHz (as if 5MHz or multiple thereof CPU clock)
  289. # pc-98 allow 4 display partition graphics: According to NEC graphics controller documentation, graphics mode is supposed to support only
  290. # 2 display partitions. Some games rely on hardware flaws that allowed 4 partitions.
  291. # -1: Default (choose automatically)
  292. # 0: Disable
  293. # 1: Enable
  294. # pc-98 force ibm keyboard layout: Force to use a default keyboard layout like IBM US-English for PC-98 emulation.
  295. # Will only work with apps and games using BIOS for keyboard.
  296. # vga bios size override: VGA BIOS size override. Override the size of the VGA BIOS (normally 32KB in compatible or 12KB in non-compatible).
  297. # video bios dont duplicate cga first half rom font: If set, save 4KB of EGA/VGA ROM space by pointing to the copy in the ROM BIOS of the first 128 chars
  298. # video bios always offer 14-pixel high rom font: If set, video BIOS will always carry the 14-pixel ROM font. If clear, 14-pixel rom font will not be offered except for EGA/VGA emulation.
  299. # video bios always offer 16-pixel high rom font: If set, video BIOS will always carry the 16-pixel ROM font. If clear, 16-pixel rom font will not be offered except for VGA emulation.
  300. # video bios enable cga second half rom font: If set, and emulating CGA/PCjr/Tandy, automatically provide the second half of the 8x8 ROM font.
  301. # This setting is ignored for EGA/VGA emulation. If not set, you will need a utility like GRAFTABL.COM to load the second half of the ROM font for graphics.
  302. # NOTE: if you disable the 14 & 16 pixel high font AND the second half when machine=cga, you will disable video bios completely.
  303. # forcerate: Force the VGA framerate to a specific value(ntsc, pal, or specific hz), no matter what
  304. # sierra ramdac: Whether or not to emulate a Sierra or compatible RAMDAC at port 3C6h-3C9h.
  305. # Some DOS games expect to access port 3C6h to enable highcolor/truecolor SVGA modes on older chipsets.
  306. # Disable if you wish to emulate SVGA hardware that lacks a RAMDAC or (depending on the chipset) does
  307. # not emulate a RAMDAC that is accessible through port 3C6h. This option has no effect for non-VGA video hardware.
  308. # sierra ramdac lock 565: When emulating High Sierra highcolor RAMDAC, assume 5:6:5 at all times if set. Else,
  309. # bit 6 of the DAC command selects between 5:5:5 and 5:6:5. Set this option for demos or
  310. # games that got the command byte wrong (MFX Transgrassion 2) or any other demo that is
  311. # not rendering highcolor 16bpp correctly.
  312. # page flip debug line: VGA debugging switch. If set, an inverse line will be drawn on the exact scanline that the CRTC display offset registers were written.
  313. # This can be used to help diagnose whether or not the DOS game is page flipping properly according to vertical retrace if the display on-screen is flickering.
  314. # vertical retrace poll debug line: VGA debugging switch. If set, an inverse green dotted line will be drawn on the exact scanline that the CRTC status port (0x3DA) was read.
  315. # This can be used to help diagnose whether the DOS game is propertly waiting for vertical retrace.
  316. # cgasnow: When machine=cga, determines whether or not to emulate CGA snow in 80x25 text mode
  317. # vga 3da undefined bits: VGA status port 3BA/3DAh only defines bits 0 and 3. This setting allows you to assign a bit pattern to the undefined bits.
  318. # The purpose of this hack is to deal with demos that read and handle port 3DAh in ways that might crash if all are zero.
  319. # By default, this value is zero.
  320. # unmask timer on int 10 setmode: If set, INT 10h will unmask IRQ 0 (timer) when setting video modes.
  321. # unmask keyboard on int 16 read: If set, INT 16h will unmask IRQ 1 (keyboard) when asked to read keyboard input.
  322. # int16 keyboard polling undocumented cf behavior: If set, INT 16h function AH=01h will also set/clear the carry flag depending on whether input was available.
  323. # There are some old DOS games and demos that rely on this behavior to sense keyboard input, and this behavior
  324. # has been verified to occur on some old (early 90s) BIOSes.
  325. # allow port 92 reset: If set (default), allow the application to reset the CPU through port 92h
  326. # enable port 92: Emulate port 92h (PS/2 system control port A). If you want to emulate a system that predates the PS/2, set to 0.
  327. # enable 1st dma controller: Emulate 1st (AT) DMA controller (default). Set to 0 if you wish to emulate a system that lacks DMA (PCjr and some Tandy systems)
  328. # enable 2nd dma controller: Emulate 2nd (AT) DMA controller (default). Set to 0 if you wish to emulate a PC/XT system without 16-bit DMA.
  329. # Note: mainline DOSBox automatically disables 16-bit DMA when machine=cga or machine=hercules, while DOSBox-X does not.
  330. # allow dma address decrement: If set, allow increment & decrement modes as specified in the 8237 datasheet.
  331. # If clear, always increment the address (as if to emulate clone 8237 implementations that skipped the inc/dec bit).
  332. # enable 128k capable 16-bit dma: If true, DMA controller emulation models ISA hardware that permits 16-bit DMA to span 128KB.
  333. # If false, DMA controller emulation models PCI hardware that limits 16-bit DMA to 64KB boundaries.
  334. # If auto, the choice is made according to other factors in hardware emulation
  335. # Possible values: true, false, 1, 0, auto.
  336. # enable dma extra page registers: If set, emulate the extra page registers (I/O ports 0x80, 0x84-0x86, 0x88, 0x8C-0x8E), like actual hardware.
  337. # Note that mainline DOSBox behavior is to NOT emulate these registers.
  338. # dma page registers write-only: Normally (on AT hardware) the DMA page registers are read/write. Set this option if you want to emulate PC/XT hardware where the page registers are write-only.
  339. # enable slave pic: Enable slave PIC (IRQ 8-15). Set this to 0 if you want to emulate a PC/XT type arrangement with IRQ 0-7 and no IRQ 2 cascade.
  340. # enable pc nmi mask: Enable PC/XT style NMI mask register (0xA0). Note that this option conflicts with the secondary PIC and will be ignored if the slave PIC is enabled.
  341. # rom bios 8x8 CGA font: If set, or mainline compatible bios mapping, a legacy 8x8 CGA font (first 128 characters) is stored at 0xF000:0xFA6E. DOS programs that do not use INT 10h to locate fonts might require that font to be located there.
  342. # rom bios video parameter table: If set, or mainline compatible bios mapping, DOSBox will emulate the video parameter table and assign that to INT 1Dh. If clear, table will not be provided.
  343. # allow more than 640kb base memory: If set, and space is available, allow conventional memory to extend past 640KB.
  344. # For example, if machine=cga, conventional memory can extend out to 0xB800 and provide up to 736KB of RAM.
  345. # This allows you to emulate PC/XT style memory extensions.
  346. # vesa lfb base scanline adjust: If non-zero, the VESA BIOS will report the linear framebuffer offset by this many scanlines.
  347. # This does not affect the linear framebuffer's location. It only affects the linear framebuffer
  348. # location reported by the VESA BIOS. Set to nonzero for DOS games with sloppy VESA graphics pointer management.
  349. # MFX "Melvindale" (1996): Set this option to 2 to center the picture properly.
  350. # allow hpel effects: If set, allow the DOS demo or program to change the horizontal pel (panning) register per scanline.
  351. # Some early DOS demos use this to create waving or sinus effects on the picture. Not very many VGA
  352. # chipsets allow this, so far, only ATI chipsets are known to support this effect. Disabled by default.
  353. # allow hretrace effects: If set, allow the DOS demo or program to make the picture wavy by playing with the 'start horizontalretrace' register of the CRTC during the active picture. Some early DOS demos (Copper by Surprise!productions) need this option set for some demo effects to work. Disabled by default.
  354. # hretrace effect weight: If emulating hretrace effects, this parameter adds 'weight' to the offset to smooth it out.
  355. # the larger the number, the more averaging is applied. This is intended to emulate the inertia
  356. # of the electron beam in a CRT monitor
  357. # vesa modelist cap: IF nonzero, the VESA modelist is capped so that it contains no more than the specified number of video modes.
  358. # Set this option to a value between 8 to 32 if the DOS application has problems with long modelists or a fixed
  359. # buffer for querying modes. Such programs may crash if given the entire modelist supported by DOSBox-X.
  360. # Warcraft II by Blizzard ................ Set to a value between 8 and 16. This game has a fixed buffer that it
  361. # reads the modelist into. DOSBox-X's normal modelist is too long and
  362. # the game will overrun the buffer and crash without this setting.
  363. # vesa modelist width limit: IF nonzero, VESA modes with horizontal resolution higher than the specified pixel count will not be listed.
  364. # This is another way the modelist can be capped for DOS applications that have trouble with long modelists.
  365. # vesa modelist height limit: IF nonzero, VESA modes with vertical resolution higher than the specified pixel count will not be listed.
  366. # This is another way the modelist can be capped for DOS applications that have trouble with long modelists.
  367. # vesa vbe 1.2 modes are 32bpp: If set, truecolor (16M color) VESA BIOS modes in the 0x100-0x11F range are 32bpp. If clear, they are 24bpp.
  368. # Some DOS games and demos assume one bit depth or the other and do not enumerate VESA BIOS modes, which is why this
  369. # option exists.
  370. # allow low resolution vesa modes: If set, allow low resolution VESA modes (320x200x16/24/32bpp and so on). You could set this to false to simulate
  371. # SVGA hardware with a BIOS that does not support the lowres modes for testing purposes.
  372. # allow 32bpp vesa modes: If the DOS game or demo has problems with 32bpp VESA modes, set to 'false'
  373. # allow 24bpp vesa modes: If the DOS game or demo has problems with 24bpp VESA modes, set to 'false'
  374. # allow 16bpp vesa modes: If the DOS game or demo has problems with 16bpp VESA modes, set to 'false'
  375. # allow 15bpp vesa modes: If the DOS game or demo has problems with 15bpp VESA modes, set to 'false'
  376. # allow 8bpp vesa modes: If the DOS game or demo has problems with 8bpp VESA modes, set to 'false'
  377. # allow 4bpp vesa modes: If the DOS game or demo has problems with 4bpp VESA modes, set to 'false'
  378. # allow tty vesa modes: If the DOS game or demo has problems with text VESA modes, set to 'false'
  379. # double-buffered line compare: This setting affects the VGA Line Compare register. Set to false (default value) to emulate most VGA behavior
  380. # Set to true for the value to latch once at the start of the frame.
  381. # ignore vblank wraparound: DOSBox-X can handle active display properly if games or demos reprogram vertical blanking to end in the active picture area.
  382. # If the wraparound handling prevents the game from displaying properly, set this to false. Out of bounds vblank values will be ignored.
  383. #
  384. # enable vga resize delay: If the DOS game you are running relies on certain VGA raster tricks that affect active display area, enable this option.
  385. # This adds a delay between VGA mode changes and window updates. It also means that if you are capturing a demo or game,
  386. # that your capture will also show a few garbled frames at any point mode changes occur, which is why this option is disabled
  387. # by default. If you intend to run certain DOS games and demos like DoWhackaDo, enable this option.
  388. # resize only on vga active display width increase: If set, changes to the Display End register of the CRTC do not trigger DOSBox to resize it's window
  389. # IF the value written is less than the current value. Some demos like DoWhackaDo need this option set
  390. # because of the way it's raster effects work. If the DOSBox window rapidly changes size during a demo
  391. # try setting this option. Else, leave it turned off. Changes to other VGA CRTC registers will trigger

  812. # and data without polling the DSP to ensure it's ready or b) can get locked into the IRQ 0 handler
  813. # waiting for DSP status when instructed to play at or beyond the DSP's maximum direct DAC sample rate.

  818. # dsp busy cycle rate: Sound Blaster 16 DSP chips appear to go busy periodically at some high clock rate
  819. # whether the DSP is actually doing anything for the system or not. This is an accuracy
  820. # option for Sound Blaster emulation. If this option is nonzero, it will be interpreted

  822. # blaster emulation will automatically choose a setting based on the sbtype= setting
  823. # dsp busy cycle always: If set, the DSP busy cycle always happens. If clear, DSP busy cycle only happens when
  824. # audio playback is running. Default setting is to pick according to the sound card.
  825. # dsp busy cycle duty: If emulating SB16 busy cycle, this value (0 to 100) controls the duty cycle of the busy cycle.

  1114. # zero int 67h if no ems: If ems=false, leave interrupt vector 67h zeroed out (default true).
  1115. # This is a workaround for games or demos that try to detect EMS by whether or not INT 67h is 0000:0000 rather than a proper test.
  1116. # This option also affects whether INT 67h is zeroed when booting a guest OS
  1117. # emm386 startup active: If set and expanded memory is set to emulate emm386, start the DOS machine with EMM386.EXE active
  1118. # (running the 16-bit DOS environment from within Virtual 8086 mode). If you will be running anything

  1126. # If the DOS game or demo fiddles with the A20 gate while using EMM386.EXE emulation in virtual 8086 mode, setting this option may help prevent crashes.
  1127. # However, forcing allocation on an even megabyte will also cause some extended memory fragmentation and reduce the
  1128. # overall amount of extended memory available to the DOS game depending on whether it expects large contiguous chunks
  1129. # of extended memory.
  1130. # umb: Enable UMB support.
  1131. # umb start: UMB region starting segment
  1132. # umb end: UMB region last segment
  1133. # kernel allocation in umb: If set, dynamic kernel allocation=1, and private area in umb=1, all kernel structures will be allocated from the private area in UMB.
  1134. # If you intend to run Windows 3.1 in DOSBox, you must set this option to false else Windows 3.1 will not start.
  1135. # dynamic kernel allocation: If set, DOS kernel structures are allocated dynamically. If clear, DOS kernel structures are fixed at specific segments (mainline DOSBox behavior)
  1136. # keep umb on boot: If emulating UMBs, keep the UMB around after boot (Mainline DOSBox behavior). If clear, UMB is unmapped when you boot an operating system.

  1138. # private area in umb: If set, keep private DOS segment in upper memory block, usually segment 0xC800 (Mainline DOSBox behavior)
  1139. # If clear, place private DOS segment at the base of system memory (just below the MCB)
  1140. # ver: Set DOS version. Specify as major.minor format. A single number is treated as the major version (LFN patch compat). Common settings are:

  1150. # biosps2: Emulate BIOS INT 15h PS/2 mouse services
  1151. # Note that some OS's like Microsoft Windows neither use INT 33h nor

  1153. # for PS/2 mouse support. In other cases there is no harm in leaving this enabled
  1154. # int15 wait force unmask irq: Some demos or games mistakingly use INT 15h AH=0x86 (WAIT) while leaving the IRQs needed for it masked.
  1155. # If this option is set (by default), the necessary IRQs will be unmasked when INT 15 AH=0x86 is used so that the game or demo does not hang.
  1156. # int15 mouse callback does not preserve registers: Set to true if the guest OS or DOS program assigns an INT 15h mouse callback,
  1157. # but does not properly preserve CPU registers. Diagnostic function only (default off).
  1158. # keyboardlayout: Language code of the keyboard layout (or none).
