Running the SETUP Program
You may need to run the SETUP program the first time you use
your computer. If your system came unconfigured, you need to
define how it is set up. If your system was configured for you,
you may still need to set the date and time. You also may need
to run the program again later if you change your configuration.
The SETUP program is stored in the computer’s ROM BIOS
(read-only memory, basic input/output system). SETUP lets
you verify or change the following:
Current date and time
Type of video display adapter
System memory
Type of diskette drive(s) and hard disk drive(s)
External cache
Shadow and memory mapping options
Chipset register options
System booting sequence
Password security.
The configuration information is stored in an area of memory
called CMOS RAM. This memory is backed up by a battery, so
it is not erased when you turn off or reset the computer.
