OT: Diagnostics?

[AgentZero]

Hi folks,
I'm trying to fix a friend's laptop that he recently bought second hand. The problem is that as soon as he got it, he formatted the HD to remove Windows 2000, and put on Win98. Unfortunately, he didn't get any of the drivers for the laptop, so a lot of stuff didn't work. I've managed to get everything up and running except the video adapter. The reason for this is that neither of us know what kind he has. The laptop is a Dell, but the little sticker on the laptop with the code that tells Dell exactly what system you have is missing.
I'm wondering if there's any sort of diagnostic program out there that can tell me what sort of hardware he's got on the machine when the drivers for the device aren't installed. Right now it's running on 16 colour mode which is just U G L Y.
