Supermicro X9SCM-F no longer booting

[Faldaani]

Hi

Flashed an M1015 from IR to IT mode, couldnt find controller using megacli (but disks showed), flashed back to IR mode. Still couldn't. Did an "rmmod mpt3sas" in Ubuntu, got a kernel panic, restarted the server.

CONSTANT BEEPING.
BEEP BEEP BEEP BEEP BEEP BEEP (I think it was 5.. or 6) <pause> <repeat>
POST snooping in IPMI is all over the place, looks like its in an infinite reboot loop.

Reset CMOS, pulled battery. No difference.

Pulled a RAM stick, now it no longer repeats the beeping, it just beeps 6 times and the post code is 55 which indicates no memory present.

If I fill the RAM up with all modules it goes back to infinite beeping.

I've tried all combinations of RAM sticks that previously worked, in 1, 2, 3 and 4 module combinations.
In some 3-memory configurations it stops at post code 00.

IPMI sensors view has no readings. IPMI console or serial console is blank.
Unfortunately I have no monitor with VGA input (or any monitor at all for that matter), so I don't know if it tries to output something via VGA.

This server has worked fine for YEARS.

Help.

EDIT: All cards and harddrives have been unplugged

Have you removed the m1015? I assume you have but just to be sure. and all other cards?

Yep, all cards are gone. All harddrives are unplugged.

Only thing plugged into the motherboard is the power, a few fans and the standard headers needed for LED/power button. Even pulled the intrusion switch and tried different fans incase it was a RPM alarm.

I've confirmed that CPU and RAM work in another machine.
So I guess that the mobo is dead.

Amazing that some combination of flashing an LSI card and unloading a kernel module can fry a motherboard.
I'm afraid of plugging that LSI card into another machine..
