 * IBM Personal Computer/AT Compatibles.
 * --------------------------------------
 * kernel/machine/ibmpc.c
 * This "host machine" driver is responsible for running IBM PC
 * compatible computers. This driver creates the host bus on boot,
 * enables PCI bus (kernel/drivers/pci) support to the system,
 * which is supplied with most modern IBM PC Compatible systems.
 * It also installs the main chip drivers that come with most IBM
 * PC-Compatible, like the i8042 chip (kernel/drivers/ps2/i8042.c)
 * and Intel's 8259A interrupt controller (kernel/drivers/pic/8259A.c).
 * On the other hand, The driver enables support for "system console"
 * during boot, allowing the kernel to print status messages to the
 * system console of the PC, until the actual video drivers are loaded.
