PNP and PCI Setup

TXP4-X P5A, P2L97, P2B, P2B-F, & P2-99

On the P5A main board, the BIOS default is for “Slot 3/Audio IRQ” to be set for IRQ 5. This must

changed to “Auto” to avoid a conflict with COM3.

The “PCI Latency Timer” should be left at “0 PCI Clock” to avoid problems.

When using an ISA serial card, the “IRQ # Used By ISA” options for 5 and 9 should be “Yes.” If the PCI

card is being used, leave both of these options on “No/ICU.”
