You're welcome! and thanks for that bit of info. Glad to know the IBM1210 can flash as well. They seem hard to find, and a few blood-suckers have them listed on eBay for like $200 bucks, lol.Hello Sleyk, thank you for documenting your experiences and providing all of this information.
I successfully cross-flashed IBM ServeRAID M1210 to Avago 9300-4i IT mode.
There's no J6 header soldered on the M1210 although the vias exist.
I would caution anyone who wants to flash this card: do not add a jumper or bridge the vias as this will fry your card.
You can perform megarec3.exe and sas3flash.efi operations without the J6 jumper.
Best wishes on your continued adventures.
