Using my GPIO finder posted earlier, I have the gpio needed to enable flashing on the dell. I would like to get a patch together but have not done this mainboard enable thing. I would like to do this in the most-approved manner.
Basically need to match the dell mainboard, find the 8086:24d0 bridge, look up a BAR, and twiddle one little gpio line.
The northbridge looks like this: 00:00.0 Host bridge: Intel Corporation E7520 Memory Controller Hub (rev 09) 00: 86 80 90 35 46 01 90 00 09 00 00 06 00 00 80 00 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 28 10 6c 01 30: 00 00 00 00 40 00 00 00 00 00 00 00 00 00 00 00 40: 09 00 05 41 10 00 00 00 00 00 00 00 00 00 00 00 50: 0c 20 4a 00 00 00 00 00 00 10 11 11 01 00 00 10 60: 10 10 10 10 20 20 30 30 00 00 00 00 00 00 00 00 70: 0a 00 0a 0a 00 00 00 00 44 11 5e 55 1e 02 20 2c 80: 41 28 41 00 00 00 00 00 80 01 00 f0 88 00 00 00 90: 00 00 00 00 00 aa 04 39 aa aa 0c 30 75 08 12 07 a0: 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 b0: cc 00 99 55 00 00 00 00 00 00 00 00 00 00 00 00 c0: 44 c0 50 33 00 e0 60 00 67 00 28 00 30 00 00 e0 d0: 02 28 00 0e 03 00 00 00 00 00 93 b5 00 00 00 00 e0: 00 00 00 00 00 00 00 00 34 3e 00 00 00 00 00 00 f0: 00 00 00 00 10 01 02 00 80 0f 0c 00 00 00 00 00
