Hard Drive
Hard disk failure.
1. Make sure the correct driv e type for the hard disk driv e has been entered in the BIOS .
2. If the system is configured with two hard driv es, make sure the bootable (first) hard driv e
is configured as Master and the second hard driv e is configured as Sla ve. The master hard
drive must have an active/bootable partition.
Excessively long formatting period.
If your hard drive takes an excessively long period of time to f ormat, it is lik ely a cable con-
nection problem. However, if your hard drive has a large capacit y, it will tak e a longer time to
format.
Serial Port
The serial device (modem, printer) doesn’t output anything or is outputting garbled
characters.
1. Make sure that the serial device’ s power is turned on and that the device is on-line.
2. Verify that the device is plugged into the correct serial port on the rear of the computer .
3. Verify that the at tached serial device works by at taching it to a serial port that is working
and configured correctly. If the serial device does not work, either the cable or the serial

I/O or the address set ting.
