Hello,
There are 2 ways you can reset your bios.
1.
On the motherboard there is
a small watch battery. Remove this battery along with the power cable
from the power supply. Hold down the power button to fully discharge the
system. Wait 2-3 minutes then reinstall the battery and plug in
your system. Your reset is now complete
2. Some motherboards have a 3
pin jumper by the battery. Lets say that the jumper is on pins 2 and 3.
Remove the jumper while the machine is OFF and place onto pins 1 and 2.
Power on your machine for a minute. (Note: Your system will not POST).
Shutdown your machine and put the jumper back to pins 2 and 3. Your
reset is now complete
This is a great
step for those of you having POST issues or no POSTing at all. Like
other troubleshooting steps, this will not always work but usually will
depending on the problem.
Please let me know if you have any further questions or concerns.
Thanks.

Compal manufactured this computer and it was sold under many different manufacturers names.
To remove optical drive: Extract the two screws in the base that obviously attach to the drive. Remove cover from memory, roughly in centre of base, and you will see a screw that secures the drive. Remove the screw and the drive will slide out. Remove the bracket on rear of drive, attach to new drive and reverse above procedure. Memory is located under the said cover and also under the keyboard. Not too difficult to remove keyboard. Remove switch panel after removing screws in back of hinges. You will see several screws on rear of keyboard. Remove these (very small) and keyboard will swing upwards and out. Beware ribbon cable connector underneath as removing keyboard. You will then see second memory location. Max mem 1G
