IV. BIOS SETUP IV. BIOS SETUP Plug & Play/PCI Load Setup Defaults IV. BIOS SETUP 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, 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) Auto allows the BIOS to detect whether you have a Symbios SCSI card, if detected the onboard Symbios BIOS will be enabled, if not then it will be disabled. Disabled prevents the onboard Symbios BIOS to be enabled so that the external Symbios SCSI card's own BIOS can be used instead. Note: If your Symbios SCSI card does not have a BIOS the Symbios SCSI card will not function. USB Function (Disabled) This motherboard supports Universal Serial Bus (USB) devices. Set to Enabled if you want to use USB devices. Your system must support USB function. The default setting is Disabled. USB IRQ (Auto) This field allows you to reserve an IRQ# (3, 4, 5, 7, 9, 10, 11, 12, 14, or 15) for the USB to work. Auto assigns an IRQ# automatically to your USB device. If you are not using a USB device, you may disable this feature by setting it to NA to save an extra IRQ# for other devices or expansion cards. ONB VGA BIOS First (No) This field, when set to Yes, gives priority to the onboard VGA BIOS over other VGA controllers. The default setting is No. ASUS P5S-B User's Manual 61

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, 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)
Auto
allows the BIOS to detect whether you have a Symbios SCSI card, if detected
the onboard Symbios BIOS will be enabled, if not then it will be disabled.

prevents the onboard Symbios BIOS to be enabled so that the external Symbios
SCSI card’s own BIOS can be used instead.
Note:
If your Symbios SCSI card does
not have a BIOS the Symbios SCSI card will not function.
USB Function (Disabled)

for the
USB to work.
Auto
assigns an IRQ# automatically to your USB device. If you are
not using a USB device, you may disable this feature by setting it to
NA
to save an
extra IRQ# for other devices or expansion cards.
