PCICFG 54h
IRQ Driveback Protocol Address Bits:
-
When the 82C814 logic must generate an interrupt from any source, it follows the IRQ Driveback Protocol and toggles the REQ# line to
the host. Once it has the bus, it writes the changed IRQ information to the 32-bit I/O address specified in this register. The host interrupt
controller claims this cycle and latches the new IRQ values.
-
Bits 2:0 are reserved to be 000 and are read-only.
-
This register defaults to a value of 33333330h.

IRQ Driveback Address Register - Byte 3: Address Bits [31:24]
Default = 33h
PCICFG 58h
DRQ Remap Base Address Bits:
-
The distributed DMA protocol requires DMA controller registers for each DMA channel to be individually mapped into I/O space outside
the range claimed by ISA devices. Bits A[31:0] of this register specify that base; bits 7:0 are reserved (write 0) because the base
address can fall only on 256 byte boundaries.
-
The 82C814 logic uses this base address to forward accesses across the bridge to remote devices specified in the DMA Channel Selec-
tor Register.
DRQ Remap Base Address Register - Byte 0: Address Bits [7:0]
Default = 00h
