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. No/ICU 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 ranges. The ISA MEM Block SIZE field will
then be available 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 Function (Disabled)
The baseboard supports Universal Serial Bus (USB) devices but current operating sys-
tems do not. The default is set to Disabled. If you have the necessary support disks and
USB devices, you can set this function to Enabled to use the onboard USB connector.
Passive Release (Enabled)
This function allows the passive release to be Enabled or Disabled. The default
setting of Enabled allows better performance.
