(Chipset Features)
Memory Hole at Address (None)
This feature reserves memory address space 12MB to 16MB, 14MB to 16MB, or
15MB to 16MB to ISA expansion cards that specifically require this setting. WARN-
ING: This makes the memory from the specified and up unavailable to the system
because expansion cards can only access memory up to 16MB.
Slow Refresh (1:4) (Disabled)
This function set to Enabled will decrease the DRAM refresh rate and increase the
bandwidth available for data transfers. WARNING: Some DRAM’s are known to
lose data without frequent refreshing so this function is set to Disabled by the
manuafacturer.
Onboard VGA Memory Size (1MB)
This function allows the user to allocate either 1MB or 2MB memory for the on-
board video controler. Larger memory allows more colors and a higher resoultion to
be selected within each operating system.
Onboard VGA Memory Clock (Leave on default setting of Fast)
This function allows the selection of the video speed. Normal uses 50MHz, Fast
uses 60MHz, and Fastest uses 66MHz. WARNING: If your monitor displays un-
recognizable information, you must decrease the speed to match your monitor fre-
quency rate.

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 “Dis-
abled.”
Onboard FDC Swap A: B: (No Swap)
This field reverses the drive letter assignments of your floppy disk drives in the
Swap AB setting, otherwise leave on the default setting of No Swap. This works
separately from the BIOS Features floppy disk swap feature. It is functionally the
same as physically interchanging the connectors of the floppy disk drives.
Onboard Serial Port 1 (3F8H/IRQ4)
Settings are 3F8H/IRQ4 (default), 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Dis-
abled for the onboard serial connector.
Onboard Serial Port 2 (2F8H/IRQ3)
Settings are 3F8H/IRQ4, 2F8H/IRQ3 (default), 3E8H/IRQ4, 2E8H/IRQ10, and Dis-
abled 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 (default), 278H / IRQ 5, Disabled. If you install
an I/O card with a parallel port, ensure that there is no conflict in the address assign-
ments. The PC can support up to three parallel ports as long as there are no conflicts
for each port.
