RUNNING WINBIOS SETUP
WinBIOS Setup keeps a record of the system parameters, such as
date and time, disk drives, and numeric coprocessors. The Setup
parameters reside in the Read Only Memory Basic Input/Output Sys-
tem (ROM BIOS) so that they are available each time the system is
turned on. WinBIOS Setup stores the information in the complemen-
tary metal oxide semiconductor (CMOS) memory. When the system
is turned off, a backup battery retains system parameters in the
CMOS memory.
Each time the system is powered on, it is configured with these
values, unless the CMOS has been corrupted or is faulty. The
WinBIOS Setup program is resident in the ROM BIOS (Read Only
Memory Basic Input/Output System) so that it is available each time
the computer is turned on. If, for some reason, the CMOS becomes
corrupted, the system is configured with the default values stored in
this ROM file.
As soon as the system is turned on, the power-on diagnostic routines
check memory, attempt to prepare peripheral devices for action, and
offer you the option of pressing <Del> to run WinBIOS Setup.
If certain non-fatal errors occur during the Power-On Self Test
(POST) routines which are run when the system is turned on, you
may be prompted to run WinBIOS Setup by pressing <F1>.
When selecting a certain setting for one WinBIOS Setup option
determines the available selections for one or more other WinBIOS
Setup options, WinBIOS does not permit you to use these settings un-
less the setting for the first option is changed. For example, the
Serial Port1 and Serial Port2 options in Peripheral Setup can be set to
2F8H, 3F8H, 2E8H or 3E8H. If 2F8H is selected for Serial Port1,
WinBIOS disables 2F8H as an option for Serial Port2. Invalid op-
tions are grayed on the WinBIOS Setup screen and cannot be
selected.
