Boot failure message
Explanation
formatted. Insert a system diskette, press F1, and format the
hard disk as described in your operating system manuals.
Fixed disk read failure
The hard disk may be defective. Press F1 to retry. Make sure
the drive is correctly specified in the BIOS setup utility. If the
problem persists, insert a system diskette, press F1, backup the
data held on the defective hard disk and try reformatting it.
No boot device available
This may indicate a fault in the diskette or hard disk drive, or
perhaps a damaged system diskette. Press F1 to retry, using
another system diskette, if possible. Make sure that the Startup
Devices option is correctly specified with the BIOS Setup
utility. If the problem persists contact your supplier or
authorised maintainer.
Troubleshooting checklist
If you encounter a problem with the computer the following
sections suggest checks to make before you alert your dealer,
authorised maintainer or support organisation. The checks listed
cover the causes of common problems.
Connections
Check that all power and signal cables are securely connected to the
correct port on the computer.
The keyboard and mouse are particularly easy to connect into the
wrong port. Although the connectors are identical, the keyboard
will not work if plugged into the mouse port, and vice versa.
The two serial ports also appear identical. If you have a problem
make sure that the cable is connected to the port you are trying to use.
Power
Check that the AC power supply is switched on, and that the fuse
in the AC plug (if any) has not blown. If the system still does not
seem to be getting power, obtain another power cord from your
supplier.
