This is related to an earlier thread we posted, there was older thread from some time ago about flashing graphics cards to work with El Capitan. but we have another issue to resolve first, we used the 7300 GT that came with the MP to get to the boot menu, booted up Yosemite and now for some reason we can't boot to El Capitan with the 7850 even after it's been chosen the with or without the 7300 GT installed, the 7850 boots just fine to Yosemite, but refused to go back to El Capitan (When we try to boot off the Radeon with the 7300 GT in at the same time it shows a blurry desktop and freezes without the 7300 GT installed, it just boots to Yosemite.) installed any idea what could be causing it to boot to Yosemite and not El Capitan like it was before? Do we have to resolve this before we can consider flashing or updating firmware? Currently it.s 1.1 and the El Capitan is on a partitioned drive with Yosemite, modded EFI. The 7300 GT is installed with the Radeon at the moment, the 7300 is the one that's booted off and shows only 5mb so we really need to resolve this as soon we can.
Thanks
