PNP and PCI Setup

This “PNP and PCI Setup” option configures the PCI bus slots. All PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to this value.

NOTE: SETUP Defaults are noted in parenthesis next to each function heading.

Details of PNP and PCI Setup

PNP OS Installed (No)

When Plug and Play operating systems (OS) are installed, interrupts may be reassigned by the OS when Yes is selected. When a non-Plug and Play OS is installed or to prevent reassigning of interrupt settings, select No.

Slot 1/2/3/4 IRQ (Auto)

The first four fields on the screen set how IRQ use is determined for each PCI slot. Slot 1 (Right) is nearest the memory sockets. The default setting for each field is Auto, which uses auto-routing to determine IRQ use. The other options are the manual settings of NA, 5, 7, 9, 10, 11, 12, 14, or 15 for each slot.
