System’s manufacturer. Choices are Level (default) and Edge.

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 controller.

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 partitions.
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 secondary as described in
“Slot x Using INT#” above.

Selecting “PCI Auto” allows the system to automatically determine how your IDE disk system is
configured.
