IV.
BIOS
(Chipset Features)
Delayed Transaction (Disabled)
If
Enabled
, this frees the PCI Bus during CPU accessing of 8-bit ISA cards which
normally consume about 50-60 PCI Clocks without PCI delayed transaction.
If PCI
Bus Masters cannot use the PCI Bus, leave this on the default setting of
Disabled
for
some ISA cards that are not PCI 2.1 compliant.
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.
Leave on default
setting of
Enabled
for better performance, otherwise
Disabled
.
Memory Hole at Address (None)
This features reserves either
14MB-16MB
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.
....................................................................................................................................
Onboard FDC Controller (Enabled)
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
Disabled
.
Onboard FDC Swap A & B (No Swap)
This field reverses the 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 in hardware.
This works separately from the BIOS Features floppy disk swap feature.
It is func-
tionally the same as physically interchanging the connectors of the floppy disk drives.
Onboard Serial Port 1 (3F8H/IRQ4)
Settings are
3F8H/IRQ4
,
2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10,
and
Disabled
for
the onboard serial connector.
Onboard Serial Port 2 (2F8H/IRQ3)
Settings are
3F8H/IRQ4, 2F8H/IRQ3
,
3E8H/IRQ4, 2E8H/IRQ10,
and
Disabled
for
the onboard serial connector.
