IV. BIOS SETUP Chipset Features IV. BIOS SETUP Graphics Aperture Size (64MB) Memory-mapped, graphics data structures can reside in a Graphics Aperture. Leave on default setting. Memory Hole At Address (None) This allows you to specify the memory address space to be reserved for ISA expansion cards that specifically require this setting. Setting the address space to a particular setting (available settings: 15M-16M, 14M-16M, 12M-16M) will make that memory space unavailable to the system. Expansion cards can only access memory up to 16M. The default is None. Delayed Transaction (Enabled) If Enabled, this frees the PCI Bus during CPU accessing of 8-bit ISA cards that 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. VGA Shared Memory Size (4MB) This allows you to specify the memory size (available settings: 2MB, 4MB, 8MB) to be shared with the onboard VGA controller. Default setting is 4MB...Onboard FDC Controller (Enabled) When enabled, this field 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 disk 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: Swap AB and No Swap (default). 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 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. Onboard Parallel Port (378H/IRQ7) This field sets the address of the onboard parallel port connector. You can select either 3BCH / IRQ 7, 378H / IRQ 7, 278H / IRQ 5, or Disabled. 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. IV. BIOS SETUP Chipset Features ASUS P5S-B User's Manual 55

Chipset Features
Graphics Aperture Size (64MB)
Memory-mapped, graphics data structures can reside in a Graphics Aperture. Leave
on default setting.
Memory Hole At Address (None)
This allows you to specify the memory address space to be reserved for ISA expan-
sion cards that specifically require this setting. Setting the address space to a par-
ticular setting (available settings:
15M-16M
,
14M-16M
,
12M-16M
) will make that
memory space unavailable to the system. Expansion cards can only access memory
up to 16M. The default is
None
.
Delayed Transaction (Enabled)
If
Enabled
, this frees the PCI Bus during CPU accessing of 8-bit ISA cards that
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.
VGA Shared Memory Size (4MB)
This allows you to specify the memory size (available settings:
2MB
,
4MB
,
8MB
) to
be shared with the onboard VGA controller. Default setting is
4MB
.
....................................................................................................................................
Onboard FDC Controller (Enabled)
When enabled, this field 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 differ-
ent controller card to connect the floppy disk 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:
Swap AB
and
No Swap
(default).
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
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.
Onboard Parallel Port (378H/IRQ7)
This field sets the address of the onboard parallel port connector. You can select either
3BCH / IRQ 7
,
378H / IRQ 7
,
278H / IRQ 5
, or
Disabled.
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.
