16-bit I/O Recovery Time (1 BUSCLK)
Timing for 16-bit ISA cards
8-bit I/O Recovery Time (1 BUSCLK)
Timing for 8-bit ISA cards
Video BIOS Cacheable (Enabled)
Allows the Video BIOS to be cached to allow faster execution.
Memory Hole at Address (None)
This features reserves either 15MB-16MB or 14MB-16MB memory address
space to ISA expansion cards that specifically require this setting. Memory
from 14MB and up or 15MB and up will be unavailable to the system
because expansion cards can only access memory up to 16MB.
Onboard FDC Controller (Enabled)
When enabled, this feature allows you to connect your floppy disk drives
to the onboard floppy drive connector instead of a separate controller
card. If you want to use a different controller card to connect the floppy
drives, set this field to Disabled.
Onboard FDC Swap A & B (No Swap)
This field allows you to reverse the hardware drive letter assignments of
your floppy disk drives. Two options are available: No Swap and Swap
AB. If you want to switch drive letter assignments, set this field to Swap
AB, and the swap will be controlled by the onboard chipset.
Onboard Serial Port 1 (3F8H/IRQ4)
Settings are either 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10,
or Disabled, for the onboard serial connector.
Onboard Serial Port 2 (2F8H/IRQ3)
Settings are either 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, Disabled, or
3F8H/IRQ4, for the onboard serial connector.
Onboard Parallel Port (378H/IRQ7)
This field sets the address of the onboard parallel port connector. You can
select either 378H / IRQ 7, 278H / IRQ 5, Disabled, or 3BCH / IRQ 7. If
you install an I/O card with a parallel port, ensure that there is no conflict in
the address assignments. The PC can support up to three parallel ports as
long as there are no conflicts for each port.
