You're confusing BIOS-based boot with msdos partition labels. You can use GPT just fine when booting from BIOS (although Intel tries to hide that fact by embedding the GPT spec inside the EFI spec). > I much prefer being able to put as many .efi files as fit > all on one partition, for refit to find.

That, and keeping 10.4 updated, are the two main > reasons I ever boot into MacOS :-) I think what we need here is to support MacOS boot from GRUB. Then you can use GRUB as your bootloader and don't need to use it as a piece of glue between Refit and Linux.. Want to help us on that? :-) > >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. Notice that, like "EFI", "BIOS" doesn't imply any underliing implementation; it just defines an interface (Intel uses this confusion to pretend their firmware is free, when in fact only its shell -EFI- is). Unless I missed something, Apple's BIOS is as much a BIOS as is any other one. -- Robert Millan I know my rights; I want my phone call! What good is a phone call… if you are unable to speak?
