Plug & Play / PCI

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 C800H and DFFFH 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, 36K, 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 IRQ (Enabled)

Enabled reserves an IRQ# for the USB to work, Disabled does not allow the USB to

have an IRQ# and therefore prevents the USB from functioning. If you are not using

any USB devices, you may set this feature to Disabled to save an extra IRQ# for

expansion cards.
