So after doing a little bit of research, unfortunately not enough, we bit the bullet and bought a Mac Pro 1.1 that came from University Surplus, Running El Capitan or Yosemite on a modded drive that is able run newer OS)
Configuration is as follows-
-PC AMD 2GB Radeon HD 7850 of course no boot screen
original Nvidia 7300 GT should have around 256mb
-original Apple optical drive
-16gb RAM
-160gb HDD (modded drive includes80gb partitions for both OS's)
Currently booted on El Capitan with the Nvidia card added at the moment but only showing 5mb in About This Mac, but the AMD card is still in the slot we only disconnected the power cable from the motherboard, so on the first run after reinstalling the Nvidia the slot utility came up, we changed lanes or something like that and the slot utility is no longer coming up, but the card still shows only 5mb. Took out the AMD card and placed the Nvidia in the same first slot still reporting only 5mb, could the card be defective or does the slot need to configured correctly? Please see the embedded Expansion Slot Utility Screen Shot, We would like to have both cards installed since we need the boot screen for Recovery Mode and Bootcamp. The AMD card has a lot more power, we are trying to see if there is any way to flash it so that it will work with the boot screen. So we checked the firmware it shows MP11.005C.B08 a quick search shows that to be EFI 1.1, does anyone know if we update the firmware to 2.1 will that interfere with the Modded drive? There is a old Mac Pro 1,1 to 21 thread on here on Mac Rumors but it seems posting to it would be pointless since it was last active in 2012. Any ideas why the Nvidia card only shows 5mb in About This Mac? Could this be because the modded system is not compatible with the Nvidia card and will only work with the stock system or Lion?
Will future updates kill this modded drive all together, will we wind up having to downgrade to Lion? Can someone please explain what is it that makes this HDD modded and how it affects performance, etc? Can we create either a dvd or usb install/rescue disk for the drive or are we pretty much out of luck if the system crashes? Is there any possible chance in the future that future OS X might work or is this the end of the road for the 1.1? It's a lot of questions but we have searched and have found very little info.
We don't mind spending a little more to make this viable and not have to get something else at the moment, however a 1 GB graphics Mac Pro AMD graphics card is over $100 used and we don't even know if it would be compatible with this modded OS X drive?
We appreciate any helpful suggestions or tips.
Thanks
