IV. BIOS SOFTWARE
ISA MEM Block BASE (No/ICU)
This field allows you to set the base address and block size of a legacy ISA card that
uses any memory segment within the C800, CC00, D000, D400, D800, and DC00
address range. If you have such a card, and you are not using an ICU to specify its
address range, select a base address from the six available options; the ISA MEM
Block SIZE field will then appear for selecting the block size. If you have more than
one legacy ISA card in your system that requires to use this address range, you can
increase the block size to either 8K, 16K, 32K, or 64K. If you are using an ICU to
accomplish this task, leave ISA MEM Block BASE to its default setting of No/ICU.
SYMBIOS SCSI BIOS (Auto)
The default uses Auto settings for the onboard SCSI BIOS. If you do not want to use
the onboard SCSI BIOS, choose Disabled.
USB Function (Disabled)
The motherboard supports Universal Serial Bus (USB) devices but current operating
systems do not. The default is set to Disabled. If you have the necessary support disks
and USB devices, set this function to Enabled to use the onboard USB connector.
USB IRQ (Auto)
When USB devices are connected to the onboard USB connector, the resource set-
tings or IRQs for these devices are, by default, automatically assigned by the BIOS.
You may manually select the settings: 5, 7, 9, 10, 11, 12, 14, and 15. If you are not
using any USB devices, you may set this field to N/A.
Load BIOS Defaults
This "Load BIOS Defaults" option allows you to load the troubleshooting default
values permanently stored in the BIOS ROM. These default settings are non-opti-
mal and disable all high performance features. This feature does not affect the fields
on the Standard CMOS Setup screen.
