General Description

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

load KZPBA PKA bus=qbb_1_pca_1_pci_0

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

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.

 No support for Multi-Function PCI devices in AlphaServer 400.

Example: Loading DE435 into slot 0:

 The "irq_bus=isa" setting is specific to AlphaServer 400 only.

AlphaServer 800 (4 PCI slots)

In addition to 4 PCI vacant slots there are 3 PCI positions occupied by on-board devices. All 5 7 PCI positions are listed in the following table in the order in which Alpha SRM console enumerates them.

AlphaServer 800 (4 PCI slots)

In addition to 4 PCI vacant slots there are 3 PCI positions occupied by on-board devices. All 7 PCI positions are listed in the following table in the order in which Alpha SRM console enumerates them.

The IRQ stands for input line of ASIC interrupt controllers. It has nothing to do with "EISA" style interrupts. So far, the CHARON-AXP emulators do not emulate S3 Trio32/64 Display Adapter. So position of the device 6, function 0 on the PCI 0 remains empty.

Example 1: Loading multiple DE500BA’s into slot 3, populating all 4 functions (gives 4 Ethernet ports):

Example 2: Loading mixture of KZPBA and DE500BA into slot 1, populating 2 functions out of 4:

 In the above examples device name is PKB as there is a built-in PK-like PCI SCSI Adapter located “closer” to CPU and therefore assigned name PKA.
