Keys not working in Ubuntu server

I'm trying to set up Ubuntu server 7.04 on a PIII machine, for some reason my keyboard doesn't work correctly. the following keys do not work A S D F J K L ; '
Also 1 2 3 on the 10-key pad do not work. I have tested the keyboard on a different system and all of the keys work, but that system is a windows machine. the keyboard is a wal-mart cheapy 107 Key Keyboard. There is two things I believe may be causing this; 1. When I first got the system the old keyboard had water in it when I plugged it in, and I believe it may have fried my motherboards PS/2 slot (motherboard is a Asus P3v133). 2. the type of keyboard is not supported by the version of linux I'm using. If anyone knows of a patch or a setting to change to match my keyboard up, I could try that. If that doesn't work I think I have to get a new motherboard. Thanks in advance for any help I can get!

Hi

To check if there's something wrong with the keyboard, try to go into the BIOS of the computer and check if all the keys work. The BIOS usually have a section for password where you can type anything you want. Probably not a good idea to save the changes afterwards if you don't want a BIOS password.

From the symtoms, it sounds to me like there's some hardware error. It might be cheaper to get a USB keyboard instead of a new motherboard, but I'd test if it works first if that's possible.
