The IRQ stands for bit position in DRIR of TITAN chip. It has nothing to do with “ISA” style interrupts which are routed to IRQ 55 (including ALi M1543C PCI IDE/ATAPI controller).
So far the CHARON-AXP emulators do not support virtual ALi M1543C PCI USB adapter. So position of the device 19, function 0 on the PCI 0 remains empty.
