IRQ xx Used By ISA
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 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
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
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.
NCR SCSI BIOS
The default uses Auto settings for the onboard NCR SCSI BIOS (see section VI). If
you wish not to use the onboard NCR SCSI BIOS, choose Disabled
USB Function
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
This function allows the passive release to be Enabled or Disabled. The default
setting of Enabled allows better performance.
