PC EFI V10.4.1

New version of chameleon based booter includes these new abilities:

  • GraphicsEnabler now supports Radeon hd 2/3 series too, but only for Leopard
  • GraphicsEnabler now set up bin_image property for all radeon hd cards found in system, should fix 100% fan speed issue.
  • You can tell GraphicsEnabler(GE) to use custom version of bios(for overcloking/changing fan speed/ etc). Use option -useatirom, and GE will look for bios files in /Extra folder (from root and boot partitions, Extra from root partition has more priority). Place bios files to Extra folder and rename them to this format – ati_XXXX_YYYY.rom, where XXXX – devid, and YYYY – vendor-id, for example rom file for 4850 should be named – ati_9442_1002.rom.
  • 3rd party sm_cpu_type patch added (well, doesnt work for me anyway) and 3d party patch to fix hibernation.
  • Proper enumerating of all pci ethernet/video devices
  • Fixed few typos
  • Support for radeon hd 4730 (rv770 based card) added to GE, the card wasn’t tested tho
  • Support for multiple Radeon hd 48×0 cards in SnowLeopard
  • Added GE support for 2600 and 3870 in snowleopard, need to remove x2000.kext to get reschange, other pre-4xxx cards need to be tested yet

Installation – make sure you have chameleon2 installed, then replace boot file in boot partition with this one – boot_10.4.1

Sources – Chameleon-2.0-RC3-r658-src_PCEFIV10.4-src.tar.bz2

Also, legacyAti4800Controller kext, to forget about adding dev-id to that kext after every update – kext, use in mkext in /Extra/

p.s. Updated Graphics Enabler now works with 10.6.2 and ati 48×0 gpus.

    Hi Netkas,
    also had a problem this week to get two gpu’s to work in SL!
    I tried two 9600GT with Graphicsenabeler on, but it only boots with one card.
    Also i tried the method with modifing the and DSDT without succes.

    I would appreciate a solution for this… Maybe a little help if it is prossible via efi and if not, maybe you have a good link! I have three monitors wich I would like to work with.

    Can’t wait for help!

    This was a visontek 4850
    I ripped the rom via a windows app. I tried using it, no go.
    I tried various other variables like: arch=i386, -legacy, platform=acpi, platform=x86pc, cpus=1, maxmem=1024, -useatirom, -x -f -v in different combinations.

    I hope this helps all those wicked coders out there…
    If anyone wants to swap a 4670 or a 4850 for a similiar card hit me up!
