Looking for some Athlon tweakage

[The Rock]

Just got me my first AMD system, specs as follows:

AthlonXP 1800+
768 megs Nanya DDR RAM (CAS2.5)
Asus A7V266-E (KT266A)
Radeon 8500 retail
Windows XP Pro

So I'm looking for any BIOS tweaks / general advice / etc. I have NOT installed the VIA 4in1s. Any advice on that too would be appreciated.
