4 Summary of the HP/Phoenix BIOS
HP/Phoenix BIOS (BIOS version: GJ.07.xx)
Disabling a device in the Configuration Menu (for example, Serial port B in
the diagram above) has the advantage of freeing the resources (such as
IRQs and peripheral addresses). Disabling a device in the Security Menu
disables the access, does not free the resources, but has the advantage of
temporarily disabling the device without losing the configuration settings.
Under the “Memory and Cache” sub-menu, memory caching can be set to
both, internal only or disabled; the memory hole can be enabled
between 15 MB and 16 MB; the graphic POST can be
disabled if there is a
Display Option ROM installed; the shadow/cache ISA option ROMs can be
made accessible if detected as being fitted.
Under the “IDE” sub-menu, multi-sector transfers can be
disabled, or set
to
2
,
4
,
8
, or
16
; the translation method can be set to
extended
or
standard; the integrated bus adapters can be set to none, primary only,
disabled, or both.
Security Menu (BIOS version: GJ.07.xx)
Sub-menus are presented for changing the characteristics and values of the
User Password and the System Administrator Password.
The “User Password” sub-menu grants access to the keyboard lock timer
option. Once this password has been set, the menu gives access to the main
sub-menu of user preferences.
Power Menu (BIOS version: GJ.07.xx)
The “Power” menu allows the user to set the standby delay. It also allows the
system administrator to decide whether the mouse is enabled as a means of
reactivating the system from Standby. It is also possible to specify whether
the space-bar is enabled as a means of reactivating the system from Off.
