Yesterday i placed a new CD writer in my computer, but now it starts making a problem. When i start my computer the screen comes up that the floppy disk fail and the OPTION for me to press F1 to continue and Del to setup. i've tried to press many times but the screen is still the same. all i mean is the window xp doest show up. You didn't configure the jumper configuration or you knocked loose the IDE cable.How can i configure the jumper configuration? thanks for giving some idea.Check the CD Burner's documentation for correct jumper settings. It's best to put it on the second IDE channel and set it as master. The jumper settings might also be on the back of the drive, somewhere near the actual jumper.you will also NEED to check the controller cable for floppy drive.
most main boards have the floppy controller and the IDE controller next to each other and when you plug the Cd drive cable it knock the floppy cable loose.
the correct way to setup a cd drive is to set it up on the second IDE controller.
And set it tp Master. { if you look at the back of the cd drive you should see a jump and the marking of M, S, CS
M WOULD be Master S would be slave CS would be cable select.
If you have a hard/zipdrive or other type of IDE DEVICE on the second IDE controller .
you will need to check the jumper setting on them too.
If it is set to CS and all you would need to do is set the cd to CS too .
Well that should be clear as mud to a newbie.

How about if we get all the details on the hardware - model numbers, what is in the computer and some history?
