So far the CHARON-AXP emulators do not emulate ALi M1543C PCI USB adapter. So position of the device 19, function 0 on the PCI 0 remains empty.
AlphaServer DS20 (6 PCI slots)
In addition to 6 PCI vacant slots there are 5 PCI positions occupied by on-board devices. All 11 PCI positions are listed in the following table in the order in which Alpha SRM console enumerates them.
| Slot | pci_<N> | device | function | irq | Description |
|---|---|---|---|---|---|
| 4 | 1 | 7 | 0 | 47 | <option> |

The IRQ stands for bit position in DRIR of Tsunami/Typhoon Chip. It has nothing to do with “ISA” style interrupts which are routed to IRQ 55 (including ALi M1543C PCI IDE/ATAPI controller).
Unless SCSI option is plugged into PCI slot 4, 5, or 6, the onboard SCSI controllers appear as PKA (pka7.0.0.6.0) and PKB (pkb7.0.0.106.0) respectively.
So far the CHARON-AXP emulators do not support virtual Adaptec AIC-7895 PCI SCSI adapter. Instead, virtual QLOGIC ISP1040B PCI SCSI adapter is used.
