of the main features of the HP system BIOS. This is software that provides an interface between the computer hardware and the operating system. The procedure for updating the System ROM firmware is described under "System ROM" in chapter 2. There is BIOS support for ISA "Plug and Play" accessory - HP Vectra XU 6/XXX | HP Vectra XU 6/xxx and VT 6/xxx PCs - Technical Reference M - Page 37
is as follows: ppss where pp = Primary version number and ss = Secondary version number For HP Vectra XU 6/xxx PC, all BIOS releases have GG as the prefix and 06 as the primary version number. For HP Vectra VT 6/xxx PC, all BIOS releases have GV as the prefix and 06 as the primary version number. - HP Vectra XU 6/XXX | HP Vectra XU 6/xxx and VT 6/xxx PCs - Technical Reference M - Page 38
, the BIOS binary code is the same for both PCs. The same program is downloaded in either case. However, when it is run on an HP Vectra VT 6/ xxx PC, it is copied into shadow RAM, as usual, but the "GG" prefix is then overwritten by "GV".

The system controller supports seven DMA channels, each with a pageregister used to extend the addressing range of the channel to 16 MB. The following table - HP Vectra XU 6/XXX | HP Vectra XU 6/xxx and VT 6/xxx PCs - Technical Reference M - Page 41
will be re-directed to one of the IRQ lines made available for PCI devices. All PCI devices with interrupt transfer support will use and share INTA#.A PCI device supporting multiple functionalities may use several INT lines.
