Interrupt Routing
This section describes interrupt sharing interrupt signals connected between expansion slots onboard devices. specification specifies interrupts shared between devices attached bus. most cases, small amount latency added interrupt sharing does affect operation throughput devices. some special cases where maximum performance needed from device, device should share interrupt with other devices. following information avoid sharing interrupt with add-in card. devices categorized follows specify their interrupt grouping: INTA: default, add-in cards that require only interrupt this category. almost cards that require more than interrupt, first interrupt card also classified INTA. INTB: Generally, second interrupt add-in cards that require more interrupts classified INTB. (This absolute requirement.) INTC INTD: Generally, third interrupt add-in cards classified INTC fourth interrupt classified INTD.
Resource Mapping
PIIX4E PCI-to-ISA bridge four programmable interrupt request (PIRQ) input signals. interrupt source (either onboard from add-in card) connects these PIRQ signals. Because there only four signals, some interrupt sources mechanically tied together motherboard and, therefore, share same interrupt. Table lists PIRQ signals shows signals connected expansion slots onboard interrupt sources.

example, assume add-in card interrupt (group INTA) plugged into second slot. this slot, interrupt source from group INTA connects PIRQB signal, which connected onboard interrupt sources. there other add-in cards, this card does share interrupt with other devices. Now, however, plug second add-in card that interrupts (group INTA INTB) into first slot. INTA first slot connected signal PIRQA INTB connected signal PIRQB. Therefore, second device two-function add-in card first slot will share interrupt with single-function card second slot.
NOTE
PIIX4E connect each PIRQ line internally signals 15). Typically, device that does share PIRQ line will have unique interrupt. However, certain interrupt-constrained situations, possible more PIRQ lines connected same signal. presence operating system, IOAPIC used instead PIIX4E distribute interrupts.

BIOS recovered from diskette using recovery mode (see Section 1.11.2, beginning page 49). create BIOS recovery diskette, bootable diskette must created recovery files copied recovery files available from Intel, contact Intel customer support further information. Section information contacting Intel customer support.
NOTE

Port POST Codes
During POST, BIOS generates diagnostic progress codes (POST codes) port 80h. POST fails, execution stops last POST code generated left port 80h. This code useful determining point where error occurred. Displaying POST codes requires add-in card (often called POST card). POST card decode port display contents medium such seven-segment display. These cards purchased from Microdevices other sources. following table provides POST codes that generated BIOS. Some codes repeated table because that code applies more than operation.
