General Description

Each peripheral device of CHARON-AXP connects to CHARON-AXP emulated PCI bus with the following configuration parameters:

Note that typically all or some of those parameters are specified on loading of some PCI controller in the following way:

Available PCI slots per each HP Alpha model emulated by CHARON-AXP

The tables below specifies a map of preloaded devices and available slots for each HP Alpha models emulated by CHARON-AXP.

AlphaServer 400 (3 PCI slots)

In addition to 3 PCI vacant slots there are 2 PCI positions occupied by on-board devices. All 5 PCI positions are listed in the following table in the order in which Alpha SRM console enumerates them.

The IRQ stands for ISA IRQ Number because all interrupts are routed through the Intel i82378 PCI ISA Bridge (SATURN) resident cascade of Intel i8259 interrupt controllers.

So far the CHARON-AXP emulators do not support virtual NCR 53C810 PCI SCSI adapter. Instead, virtual QLOGIC ISP1040B PCI SCSI adapter is used.
