Have to access the bootable cd via the boot screen by holding down the option key on start up. If you don’t hold down the option key, it just boots into which ever OS is set as your startup disk. Yes , I have 2 graphics cards, the stock ATI card that came with the Mac Pro, and rx580. The goal Is to remove the stock ATI card, but I need the boot screen to access the bootable cd. I haven’t found a way to execute the bootable cd from within MacOS or Windows. They are both ATI card. I swap between Mac OS and windows often and having the boot screen is the easiest way to do so. The RX580 stock does not have the boot screen EFI, which is why I am trying to flash it to do so. > In case you prefer another language then English > and this is why your mails often feature extremely > short descriptions of the situation: Please write > in your native language, by exception.
