OVL signal A1200 issue

[Giants]

Hi !

I would like to hear your opinion.
On A1200 Rev1B with Diagrom installed, I have 2 issues randomly

- (1) First, no boot, juste see this on console output
Garbage before this text was binary numbers: 1, 2, 4, 8, 16, 32, 64, 128, 240, 15, 170 and 85
To help you find biterrors

(2) But, always without doing anything, motherboard sitting on my desk.- WHEN, it succeeds booting, randomly we have -->
Testing if OVL is working: FAILED-

(3) and finaly, after a lot of reset and completely randomly and without doing anything, PCB seems working, all diagrom successfully passed.


I have managed the ROMEN on TP1
When we have issue (1), I have no activity on ROMEN
I have activity Only when it succeeds in booting (OVL issue or not)


Extra info :
- This board went through hiroshima when one of the capacitors was unsoldered, but i recovered everything.

- I found a burnt-out internal VCC line so I wrap it.
- The capacitor is new now.
- Because OVL error, I thought of a problem on the gayle
Gayle is NEW now but problems is always here.


Your Opinion !
Thks
