Alright I come with a problem that may have a fairly simple solution, but I can't figure out what it is.

Background Info:
I have an old computer with 1.2ghz AMD Athlon with 512mb RAM running (now) on Windows XP Pro (SP2) and before this it had no hard drive. So I decided that I would use it as a storage computer. I went and bought a ATA100 IDE hard drive with 500GB of storage. Previously this same computer had a 200GB drive that had absolutely no problem and it is now in my newer machine.

Anyway the install went fine and I had no problems installing XP on it. It recognizes all of my hardware and there were no errors whatsoever.

The problem comes from the fact that my system recognizes only 127GB of the very large hard drive. I Googled the problem and found that I had to enable the 48 bit LBA support from the operating system and from the BIOS. Okay so I did the first one and there was no problem on that end. Of course it's still not showing the rest of my hard drive still and I'm stumped.

So my questions are thus:

How can I find out if my BIOS supports 48 bit LBA? Is there something I need to do to enable it in the BIOS itself?

If that's not possible on my BIOS, is the next step an ATA controller card? If it is, what am I looking for exactly if I purchase one? Any advice or suggestions on this would be great. Thanks!
