AX = B18Fh BH = bus number BL = device/function number (bits 7-3 device, bits 2-0 function) CH = number of IRQ to connect CL = number of interrupt pin (0Ah=INTA# to 0Dh=INTD#) to reprogram DS = segment/selector for PCI BIOS data(real mode:
F000h; 16-bit PM: physical 000F0000h; 32-bit PM: as specified by BIOS32 services directory)
Return:
CF clear if successful AH = 00h CF set on error AH = error code (59h) (see #01243)
Note: Assumes that the calling application has determined the IRQ routing topology (see AX=B10Eh), has ensured that the selected IRQ will not cause a conflict, and will update the interrupt line configuration register on all devices which currently use the IRQ line
