So we can not use ISA interrupt mode, only use 'PCI interrupt mode'. Please check 'IREQ/INT Enable' bit in Bridge Control Register. It must be cleared if you want to use 'PCI interrupt mode'. #Offset of Bridge Control Register is 0x3E, bit number of IREQ/INT #Enable is bit 7. When IREQ/INT Enable bit is not cleard, we need some setups to use PCI interrupt mode. 1) clear IREQ/INT Enable bit. 2) setup a PCI Interrupt Router (it may be in PCI to ISA Bridge). for setting up a PCI Interrupt Router, we need to use PCIBIOS call, or read Microsoft $PIR structure in a BIOS and change a register in a PCI Interrupt Router.
