4. BIOS SETUP
OffBoard PCI IDE Card [Auto]
This feature allows you to use a PCI IDE controller card. You may specify a PCI slot
for the card or leave the default setting of [Auto] to use the card on any of the PCI
slots. Available options: [Auto] [Slot1] [Slot2] [Slot3] [Slot4] [Slot5]
OffBoard PCI IDE Primary/Secondary IRQ [Disabled]
This feature selects the interrupt routing for add-on PCI IDE devices. A single-func-
tion PCI device can only use INTA# pin. Multi-function PCI devices can use all the
pins. The option [Hardwired] means, instead of leaving the interrupt routing to the
control of the BIOS, the interrupt request lines on the add-on PCI IDE card are
wired to the ISA interrupt controller. NOTE: These two fields are only accessible
when you assign a slot to the OffBoard PCI IDE Card. Available options: [Dis-
abled] [INTA] [INTB] [INTC] [INTD] [Hardwired]
DMA Channel x [PnP]
These fields indicate whether the displayed DMA channel for each field is being
used by a PnP card or a legacy (non-PnP) ISA card. If you install a legacy ISA card
that requires a unique DMA channel, you must set the field for that channel to [ISA/
EISA].
IRQ xx [PCI/PnP]
These fields indicate whether the displayed IRQ for each field is being used by a
PnP card or legacy (non-PnP) ISA card. If you install a legacy ISA card that requires
a unique IRQ, you must set the field for that IRQ to [ISA/EISA]. For example: If
you install a legacy ISA card that requires IRQ 10, then set IRQ10 to [ISA/EISA].
Reserved Memory Size [Disabled]
Reserved Memory Address
This field allows you to set the base address and block size of a legacy ISA card that
uses any memory segment within the C0000 and DFFFH address range. If you have
such a card, and you are not using an ISA Configuration Utility (ICU) to specify its
address range, select a memory size from the three available options: [16k], [32k],
and [64k]; the Reserved Memory Address field will then be enabled for selecting
the base address.
