Getting started with the Apricot XEN-PC
Chapter 2
Instructions for backing up files can be found in your MS-DOS
manual. It is a good idea to begin by creating a bootable system
diskette containing the programs needed to partition and format
the hard disk and to restore the backed up copy. In this way,
you should be able to recover any programs or data lost by a
hard disk failure.
Using the SETUP utility
What is SETUP is a configuration utility programmed into the
SETUP? XEN-PC’s read-only memory (ROM). Because it is permanently
kept in ROM, SETUP does not need an operating system to
function and can be invoked whenever you wish to reconfigure
your computer.
SETUP’s purpose is to allow you to view and alter your
computer’s configuration. To configure a computer means to
declare its hardware components, such as the amount of memory
it has or the type of monitor, and to say how you want them
to be used. Configuring your computer is often necessary to
ensure that the software you use can recognise and exploit the
system’s capabilities.
The configuration data is kept in a special part of the computer’s
memory, known as configuration memory or CMOS memory.
This memory is sustained by a small battery, so its contents are
preserved while the computer is turned off.
Your XEN-PC arrives preconfigured, but may need to be
reconfigured after you add or remove add-on options such as
memory modules or expansion cards.
Invoking The SETUP utility can be invoked at any time from the DOS
SETUP command line. It is invoked by pressing the
CTRL
+
ALT
+
ESC
key
combination.
Once you have reconfigured your computer you can exit SETUP.
The XEN-PC will then automatically reboot, and the changes
come into effect.
A full description of the SETUP utility is given in Chapter 6
"Using the SETUP utility".
