Troubleshooting 
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 sec- ond hard drive is configured as Slave. 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 for- mat, it is likely a cable connection problem. However, if your hard drive has a large capacity, it will take a longer time to format.
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
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
2.Verify that the device is plugged into the correct serial port on the rear of the computer.
