PERIPHERIAL CONFIGURATION

ONBOARD SERIAL PORT
- AUTO
- DISABLED
- 3F8/IRQ4/COM1
- 2F8/IRQ3/COM2 -> USED
- 3E8/IRQ4/COM3
- 2E8/IRQ3/COM4

ONBOARD PARALELL PORT
- AUTO -> USED
- DISABLED
- 378
- 278
     - ECP + EPP
     - 1.9
IF 378 OR 278, POSSIBLE NEXT
PARALELL PORT IRQ: 5 OR 7, NOW: 7
PARALELL PORT DMA CHANNEL: 0 OR 1 OR 3, NOW: 3

I WAN'T TTYS1 FOR USE
IF ONBOARD SERIAL PORT IS 2F8 IN MY BIOS, THEN
setserial -g /dev/ttyS[0123]
/dev/ttyS0: No such device
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
(IF AUTO BUT NOT 2F8, THEN I HAVE ttyS0)

MAYBE BETTER THIS ("ttyS0=NO SUCH DEVICE")
sudo setserial /dev/ttyS0 uart none port 0x03f8 irq 4

setserial -g /dev/ttyS[0123]
/dev/ttyS0, UART: unknown, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
