Seagate drives are fine - I fit them to all the systems I build.
Your board may not support drives over 32Mb, and there is no BIOS update, or any other information on the website that says one way or another. The drive you mention is a 20Gb drive, so should be no problem.
The motherboard only supports ATA33 transfer rates, so the new drive (although capable of ATA100), will only work at ATA33.
The extra speed of this 7200rpm drive, however, will work OK.
All the above is subject to the caveat that there are no oddities about the board that don't appear in the specs.
