7/2 XEN-PC OWNER'S HANDBOOK
Troubleshooting
Chapter 7
Problems when starting
Power-on Whenever the Apricot XEN-PC is turned on or reset, the power-
self-test on self-test (POST) routine tests various hardware components,
including memory, and compares the actual configuration of
the machine with that recorded in configuration (CMOS) memory.
A configuration discrepancy could arise if you have just installed
or removed a hardware option (for example, if you have added
or replaced a SIMM). In this case you are prompted to invoke
the SETUP utility.
If POST detects a hardware fault, one or more error messages
are displayed. You may also be prompted to “Press the F1 key
to continue”.
Your first action should be to turn the computer off, wait at
least 30 seconds, then turn it on again to see if the error
condition is transient or persistent. Persistent POST error
messages may indicate a fault in your system. If you press F1, the
XEN-PC attempts to boot despite the error indication (for
example, if a memory chip fails POST, the computer can continue
with less memory). If the problem persists, make a note of the
error messages and the conditions under which they occur, and
consult your Apricot supplier or an approved Apricot maintainer.
Beep codes The XEN-PC uses special audio beep codes to signal certain
hardware faults. If you hear a beep code which is not accompanied
by a POST error message (see above), call your Apricot supplier
or an authorized Apricot maintainer.
Failure On the completion of POST, the XEN-PC attempts to boot
to boot from a system diskette then a bootable hard disk partition.
MS-DOS is normally pre-installed on XEN-PC systems with a
hard disk.
If necessary, your operating system manuals should tell you
how to format a blank diskette as a system diskette (for example,
DOS uses the
Format a: /s command) or how to partition
and format a hard disk (DOS uses the Fdisk utility and Format
command).
