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) EISA/ISA card. Two options are available: No/ECU and
Yes. The first option, the default value, indicates either that the displayed IRQ is not
used or an EISA Configuration Utility (ECU) is being used to determine if an EISA/
ISA card is using that IRQ. If you install a Legacy EISA/ISA card that requires a
unique IRQ, and you are not using an ECU, you must set the field for that IRQ to
Yes.
For example: If you install a Legacy EISA/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) EISA/ISA card. Available options include: No/
ECU and Yes. The first option, the default setting, indicates either that the displayed
DMA channel is not used or an ECU is being used to determine if an EISA/ISA card
is using that channel. If you install a Legacy EISA/ISA card that requires a unique
DMA channel, and you are not using an ECU, 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 EISA/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 ECU 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
EISA/ISA card in your system that requires to use this address range, you can in-
crease the block size to either 8K, 16K, 36K, or 64K.
If you are using an ECU to accomplish this task, leave ISA MEM Block BASE to
its default setting of No/ECU.
