I thought it only used 64 bit when running in EFI mode on 64 bit UEFI. Maybe I am mistaken. After all if grub is running in 32bit mode, it isn't going to be loading anything to memory above 4GB and hence has no need for 64 bit pointers. -- Len Sorensen _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
