The dummy VCB02 device emulates the QBUS registers of a VCB02 graphic controller , (at the secondary VCB02 device address) but does not implement graphic display functionality. Its purpose is to be able to use a workstation version of VMS. When this device is loaded and , VAX/VMS boots with a requires type "D" licenses (workstation) type license, the license is accepted because VMS recognizes that a VCB02 is present.Workstation). As the dummy VCB02 is located on the secondary address (0x3fff02HEX: 0x3fff02  OCT: 01777402), VMS boots using the normal console terminal without graphics capability.

The format is as follows:

load chapi dummy_vcb02

/null

dll=chapi_vcb02

set dummy_vcb02 address = 017777402 vector = 0320 display = null


Note

Since As this dummy device cannot draw graphics, CHARONCharon-VAX will can fail the initial hardware diagnostics , but it will still boot correctly.
