Delayed Transaction (Disabled)
If Enabled, this frees the PC1 Bus during CPU accessing of &bit ISA cards which
normally consume about 50-60 PC1 Clocks without PC1 delayed transaction. If PC1
Bus Masters cannot use the PC1 Bus, leave this on the default setting of Disabled for
some ISA cards that are not PC1 2.1 compliant.

Video BIOS Cacheable (Enabled)
Allows the Video BIOS to be cached to allow faster execution. Leave on default
setting of Enabled for better performance, otherwise Disabled.

This features reserves either 14MR-16MR or 15MB-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.

When enabled, this field allows you to connect your floppy disk drives to the on-
board 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 Es&led.
This field allows you to reverse the hardware drive letter assignments of your floppy
disk drives. Two options are available: No %clp and SWYJ~ 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.
