IV. BIOS

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 (non-PnP) 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.

SCSI BIOS (Auto)

The default uses Auto settings for the onboard SCSI BIOS (see section VI). If you

wish not to use the onboard SCSI BIOS, choose Disabled

USB Function (Disabled)

This motherboard supports Universal Serial Bus (USB) devices but current operat-

ing systems do not. The default is set to Disabled until support disks and USB

devices are available in which time you can set this function to Enabled.

Passive Release (Enabled)

This function allows the passive release to be Enabled or Disabled. The default

setting of Enabled allows better performance.
