It's fixed now for my hardware, Intel's new video driver in Xorg 7.3
doesn't need any BIOS hacks or anything, I believe. Anyway, I'll find
out if it works just as soon as I manage to actually get into
linux-kernel under EFI, so *if* it doesn't break, then I can keep using
that and avoid (1) the unnecessary and potentially buggy CSM, (2) the
hassles of installing a pc-bios-style bootloader on the header of one of
my partitions. (and (3) be able to report bugs (in whatever software is
affected) that happen later on when doing it that way.) It can't hurt
to try...
You don't need to use the header of one of your partitions. You can use
the MBR or even have a dedicated partition for core.img. Then you can install
the rest of GRUB in a filesystem that's not case unsensitive! ;-P
I know, but I don't entirely understand how it works and I'd rather
not... and it gives me limited options: theoretical maximum of 5 I
think, 1 in MBR and 1 in each of first four partitions (each with their
own hacks). I much prefer being able to put as many .efi files as fit
all on one partition, for refit to find. As it is, when I upgrade GRUB,
there always has to be the fear that I did something wrong that I can't
easily fix because it's not just in the location of my files (it's
hidden in mbr/partition headers), and because I can't boot into Linux
anymore because I broke the bootloader :-) It's been very lucky that I
can so far always boot into OS X without going through GRUB, and edit my
grub.cfg from there... That, and keeping 10.4 updated, are the two main
reasons I ever boot into MacOS :-)
Btw what's a CSM?
"Compatibility Support Modules", it's a name for the BIOS substitute
that Apple added to EFI to support their "Boot Camp"/Windows.
Looking at the page http://refit.sourceforge.net/myths/ "Fact: You need
BIOS compatibility for 2D/3D accelleration" (which hasn't been updated
for a long time...) it looks like if I want the console (rather than X)
to display anything, I'll still need video BIOS... good to know when
testing to see if anything works
