Hi All,
I’m writing diagnostics (kernel mode drivers) under Windows NT which are
executed at system starts up time. One of the requirements is to indicate to
the user the physical slot number a particular defective PCI device is in.
Is there a way to access the PCI IRQ Routing Table via the PCI BIOS Service
calls as specified in the PCI-to-PCI Bridge Architecture spec or to detect
the PCI IRQ Table by searching system memory from F0000h to FFFFFh for the
“$PIR” signature as mentioned in Chapter 14 on Interrupts of the PCI System
Architecture book?
Thankfully,
Thomas Ruggiero
