IRQ xx Used By ISA (No/ICU)
These fields indicate whether or not the displayed IRQ for each field is being used
by a legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The
first option, the default value, indicates either that the displayed IRQ is not used or
an ISA Configuration Utility (ICU) is being used to determine if an ISA card is
using that IRQ. If you install a legacy (non-PnP) ISA card that requires a unique
IRQ, and you are not using an ICU, you must set the field for that IRQ to Yes. For
example: If you install a legacy ISA card that requires IRQ 10, then set IRQ10 Used
By ISA to Yes.

DMA x Used By ISA (No/ICU)
These fields indicate whether or not the displayed DMA channel for each field is
being used by a legacy ISA card. Available options include: No/ICU and Yes. The
first option, the default setting, indicates either that the displayed DMA channel is
not used or an ICU is being used to determine if an ISA card is using that channel. If
you install a legacy ISA card that requires a unique DMA channel, and you are not
using an ICU, you must set the field for that channel to Yes.
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.
