Each peripheral device of CHARON Virtual Machine (VM) connects to CHARON-AXP emulated PCI bus with the following configuration parameters:

bus
| Parameter | bus |
|---|---|
| Type | Text string |
| Value | Value formats:
When specified, the bus configuration parameter tells the CHARON-AXP software the virtual PCI bus to which virtual HP Alpha system shall connect a certain virtual PCI adapter. By default the bus configuration parameter is not specified. If the bus configuration parameter is not specified, CHARON VM software connects the virtual PCI adapter to the first available virtual PCI bus. Example (AlphaServer ES40):

| Value | When specified, the device configuration parameter specifies position of a virtual PCI adapter on virtual PCI bus. By default the device configuration parameter is not specified. If the device configuration parameter is not specified, the CHARON VM software connects the virtual PCI adapter at the first available position of the virtual PCI bus. Example:

| Value | When specified, the function configuration parameter specifies position of a virtual PCI adapter on virtual PCI bus. By default the function configuration parameter is not specified. If the function configuration parameter is not specified, the CHARON VM software connects the virtual PCI a dapter at the first available position of the virtual PCI bus. Example:

Example 1: Loading DE500BA into slot 0
load DE500BA/dec21x4x EWA bus=pci_0 device=11 function=0 |
Example 2: Loading multiple DE500BA’s into slot 3, populating all 4 functions (gives 4 Ethernet ports)
|
Example 3: Loading mixture of KZPBA and DE500BA into slot 1, populating 2 functions out of 4
|
In the above example device name is PKB as there is a built-in PK-like PCI SCSI Adapter located “closer” to CPU and therefore assigned name PKA.
