Thanks all for the quick replies!
9930a.EXE and 9930a_Win.exe
- Sorry, my typo, I did try the 9930a_Win. The win version came up with the -144 error (seems to be because the laptop thinks the battery is bad even when the mains was plugged in, which lead me to updating the bios which led me to the -144 error... nice catch 22 there).
So far the trouble was getting the boot usb to work, so that I could access the dos 9930 file instead of the windows one. I was hoping there was an easy way to have it flash the bios automatically but looks like I was wrong.
