Hi!

I was trying to install ubuntu server onto an old laptop board. It wouldn't boot so I started messing with the BIOS settings to see if I could fix it.

I made a huge mistake though: I disabled USB legacy support. Since this board only has USB3 ports and the internal keyboard is broken, I can no longer do anything as all keyboards I have are still USB2 and USB2 over USB3 is disabled now.

I'm kind of looking for a way to hard reset the BIOS at this point, I've tried these things so far:

  • Removed CMOS Battery -> resets time but that's it
    Jumped pins JRST2001 and JRST2002 -> JRST2001 resets time and JRST2002 does nothing
    Jumped the data pin and ground pin on the BIOS -> no difference

Someone people had success by jumping JRST2501 but my board doesn't have these pads.

I'm pretty sure I'm SOL at this point.

Anything else I could try?
