p4s533 update bios in win2k

Built my new system yesterday with the p4s533 mobo and 1.8a chip. Today I tried the new bios updater and it worked first time.Surprised the hell outta me, but from now on I guess I won't need my bootdisk anymore(fingers firmly crossed).
Just thought I would mention this as I haven't heard of anybody else trying it out.
