I guess the only way I could get those options back would be to reinstall the motherboard drivers, but since everything is working fine, I don't think I'll mess with that.
You may want to reconsider that -- the motherboard drivers also include IDE/SATA drivers, and without those your machine likely runs the generic ones which can be a lot slower than when you use the proper ones which are written for your actual chipset.
Worse, back in the 98 days I had a bunch of subtle data corruption which magically went away after installing the motherboard drivers.
