efi on pc, it's possible

**netkas** · 05-15-2007 12:21 AM

current status

using tianocore shell on usb stick
added hfsplus.efi module there, to be able to read hfs+ partitions
patched boot.efi works fine
kernel load and runs
the only problems - graphics.
pc bootloader pass to kernel data about current video card settings (resolution , depth, base memory adress, etc) and also pc bootloader sets vesa mode before running kernel
i ripped values for vga 80x24 mode and vesa 1024x768 mode
the only problem - to set vesa mode somewhere

kernel boots fine, it's modified to utilize efi
even boots to gui, but callisto sets too bad mode for monitor, so i can't see anything, but i can get a screenshot, and sounds, so gui works fine

the only problem right now - some efi tool, which will set vesa mode on videocard, Or, adding this staff to kernel...all needed info about setting vesa mode can be found in boot-132 sources, from apple. file graphics.c. any help is good.

Sorry for my NOOB, but I don't understand what EFI is?
Please don't angry with me because of that stupid question! :-p

netkas awesome news! If you have updates on this please post them. If you need testers I really want to help!!

Netkas, answer from Kiko:

I've already seen that, we had that working sometime last year, but we never had a UGA (vesa driver for the video card). If netkas comes on to irc again soon, i'll talk with him as i might have a solution for him. Also, the aim of this is to be able to use a un-modified kernel, the kernel which boots has crc checks taken out, so not un-modified.

Also on one of our test beds we had efi booting off a cd straight to the GUI with full res change

hanibal, efi is a bios replacement. Apple used this for the intel mac's. Once we're completely done with efi there's no need to modify osx's kernel.
