Yah... interesting... I guess I would hold cntl down through the cold restart process.
I build these ram modules and test actually on an M100 with a test harness. I'll go back and see if one of these upgrades runs in an 8201 also. I know they did. Maybe something changed. Greg i thought you had alternative rams to try also? I would suggest moving 16k from bank 1 to bank 2 to prove the main board is basically ok.
