The next field is the “PCI Latency Timer”.
Do not change the default set-
ting of “32 PCI Clock” since this enables maximum PCI performance for
this motherboard.
The following describes the other user-configurable fields
on this screen:
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 lets say,
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, indi-
cates 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 us-
ing 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”.
