EFI for first-generation MacBooks
Last modified: 2009-10-07 11:35:38 EDT
Description of problem:
first-generation MacBooks (at least mine) use an Intel T5600 CPU, so x86_64 support should be available (alsp cpuinfo is showing the lm flag=64bit). When using the efidisk.img of x86_64, the MacBook won't use/recognize the prepared usb stick.
You will have to use an i686 image, so the MacBook recognizes the usb-stick with an bootia32.efi runnable.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Get a 1-gen MacBook.
2. Prepare usb-stick with x86_64/os/images/efidisk.img and boot
macBook will not recognize the problem
MacBook will recognize the usb-stick and start anaconda, including efi support.
Preparing an usb-stick with i686/os/images/efidisk.img works. But will 64bit support be available?
might this be a bug in the MacBook firmware?
