Thanks for the info, and for all the commands too; controller still works and the drives are present as expected. For anyone who stumbles across this in the future: the 7910 uses a legacy BIOS so only mptsas3.rom is needed, although there isn't much to tune in IT mode so I wouldn't bother wasting boot time.

Howdy folks, I recently acquired a Dell Precision 7910 tower (TZ7910) for free as salvage, and currently have it kitted out with an E5-2650 v3 and 64 Gb of RAM for future VM experimentation and starting a homelab. I've flashed a few H200s, H710s, and misc. PERC cards in the past so I'm somewhat familiar (if rusty) with sas2flsh and megarec. My current issue is that according to forum posts and a few old videos on the 9341-8i I need to short jumper TP12 in order to crossflash from IR to IT, and since the controller is integrated into the board it doesn't have that jumper as far as I can see. I was wondering if my vision is bad, if there's some test pads I need to solder bridge on the back of the board, or if I'll have to give up and make a RAID 0 array for each drive I plan on installing. I'd rather avoid using one of my existing IT-flashed cards since I won't have the PCIe to spare with my current shopping list of networking/IO. Here's photos of the controller info and the corner of the motherboard where the controller is located:
