AlexTheCat123:
Do you have your 16MHz XLerator installed while you're trying to boot into LOS? If so, you have to remove it and put the stock 5MHz CPU back in. The 16MHz XLerator messes with the fragile timings that LOS needs in order to read the serial number out of the video state machine ROM, causing it to fail to boot.

bmwcyclist:
I took the XLerator out and still the same behavior...

AlexTheCat123:
Strange. Maybe pop the PFG out next and revert things to the exact same configuration that things were in when LOS was working? The PFG shouldn't affect LOS at all (other than changing the SCC clock from 4MHz to 3.672MHz), but clearly something strange is going on here.
