  1. VRAM Problem

    hi all, i have a little problem. When i start my laptop, my bios found 8 mb of video memory (shared), so video acceleration doesn't works because for enable quartz extreme you must have 16 mb video memory! Some people have the same problem? I had the same problem in linux and i fixed it, i modified /proc/mtrr and i enable 64 mb of shared video memory! This work prefectly, but in Darwin i don't know how to modify mtrr. There's AppleMTRRSupport.kext in Extension but i don't know how to modify it for adding video memory... help me please!
  2. hi all, for fix vga problem at boot follow this istruction: - reboot system in single mode exec in shell: mount -uw / - go to /System/Library/Extensions - make a directory in your home (root home is /var/root, for others users is /Users/"shortname") - move all video extension to this new folder, except your Video Extension ( my video card is Intel830, my extension is IONDRVSupport.kext, AppleIntelIntegratedGraphics.kext and AppleIntel830* ) now exec: sync sh /etc/rc if view blue screen and login windows... work! else see into every video extension (.kext) and find the dependencies (another method for find dependencies is manual load extension with: kextload -t file.kext if extension not load you can view every error ) enjoy man
