Boot loader messed up - How do I fix?

[Rudy Rucker]

I figured this out.  Here was the problem:
  I put a USB keychain drive on my box and F5 was pointing to that.
  When I removed the USB device, F5 booted off my 3Ware card, as desired.

I am guessing that if I leave the USB drive in, redo boot0cfg on Drive 
1, then my boot menu (on Drive 1) would have something like this:

  F1: ??       (windoze)
  F2: FreeBSD
  F4: Drive 2  (USB drive)
  F5: Drive 3  (3Ware RAID card)

sort of know what I am doing ;)
