@NorthAmTransAm--
I'm trying to get my AR AIC to work reliably with the apple Thunderbolt Display.
in the ROM repo, Casey lists 2 rom's by Elias64Fr, and one by you. yours has NVM21 in the file name.
when I use Elias's ROM, the display functions properly but the display doesn't light up when I wake the computer from sleep. so I thought I would try yours.
I boot with a secondary monitor attached and at the transition to the desktop, the TB display never lights up. I've booted with the mobo header connected, pins 3 and 5 jumpered, and with nothing connected to the 5-pin connector on the AR.
in the About this Mac panel, I click Displays, and both displays are reported. in system information--thunderbolt, the TB display shows as connected. all looks good except nothing on the TB display!.
I noticed in system information--thunderbolt it says Firmware version 33. maybe that's why it's not fully operational. do you have an NVM20 version, or maybe the NVM21 version, since when I download what is named GC-ALPINE-RIDGE-NVM21-V3-NATA.bin reports as Firmware version 33.
thanks!
