Since you indicate you CAN get into Bios ('Now my hard drives will not show in the bios');

First, get ALL the data you can from your present Bios chip and write it down (see Step 9 here; http://support.gateway.com/s/tutorials/Tu_949670.shtml and read this; http://www.badflash.com/biosdownload.html )

Let's start off simple - does your Gateway have a floppy disk drive?

If so, you need to create a bootable floppy with the correct Bios flash program and Bios data (this would be from the Gateway site for your specific make and model and recognizing the hardware you are going to use, most importantly the CPU.

You then set Boot priority to (as it should always be) floppy, cd, hard drive.

Then insert the floppy, shut down, and restart and follow directions to Flash the Bios.

Failing that, order a replacement chip from an on-line Bios chip seller.
