I'm finally trying to learn this SB platform.
 
Been using IDE mode with a Vrap - working great.
 
I keep dropping my DVD drive.  No biggie, don't need it..
 
But when trying to push bclock/memory further last night, I lost USB altogether.  Mouse won't work and the drive LED on USB sticks won't even blink.  Also, I lost all my BIOS saved profiles.  PS/2 keyboard works and I can get into BIOS and boot into OS - but no USB. 
 
Was gonna re-flash the BIOS to see if it was just borked, but how does one do that without USB or DVD working??
 
I just remembered the dual BIOS switch.  

  Try that tonight.....
 
If that doesn't do it, any other suggestions?
