PCI IDE IRQ Map to
This items allows you to configure your system to the type of IDE disk controller in use.
By default, Setup assumes that your controller is an ISA device rather than a PCI control-
ler.
If you have equipped your system with a PCI controller, changing this allows you to
specify which slot has the controller and which PCI interrupt (A, B, C or D) is associated
with the connected hard drives.
Remember that this setting refers to the hard disk drive itself, rather than individual parti-
tions. Since each IDE controller supports two separate hard disk drives, you can select the
INT# for each. Again, you will note that the primary has a lower interrupt than the second-
ary as described in
“Slot x Using INT#”
above.
Selecting
“PCI Auto”
allows the system to automatically determine how your IDE disk
system is configured.
Assign IRQ for USB
This item allows the user to set BIOS IRQ Routing table Enabled or Disabled.
