Hard Drive
Hard disk failure.
1.Make sure the correct drive type for the hard disk drive has been
entered in the BIOS.
2.If the system is configured with two hard drives, make sure the
bootable (first) hard drive is configured as Master and the second
hard drive is configured as Slave.
Excessively long formatting period.
1.If your hard drive takes an excessively long period of time to format,
it is likely a cable connection problem.
Parallel Port
The parallel printer doesn’t respond when you try to print.
1.Make sure that your printer is turned on and that the printer is on-
line.
2.Make sure your software is configured for the right type of printer
attached.
3.Verify that the onboard LPT port’s I/O address and IRQ settings are
configured correctly.
4.Verify that the attached device works by attaching it to a parallel port
that is working and configured correctly. If it works, the printer can
be assumed to be in good condition. If the printer remains
inoperative, replace the printer cable and try again.
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.
