stevegut78 Posted July 2, 2007 Share Posted July 2, 2007 Hell all, this is my first post and my first Mac. I have been on the "other side of the fence" for 15yrs but have worked with macs throughout my career. I have a 1.83Ghz mini and I tried to install the Leopard preview given out at WWDC. The install goes without problems but once I reboot I get the following error: Unable to find the driver for this platform "ACPI" I've had issues with ACPI and Linux before. Has anyone else had this problem when installing Leopard? I'm thinking disable ACPI in the BIOS. Can you even get into the BIOS on a Mac? Any help would be appreciated. PS, I've read through a ton of msgs and havent found anyone running 10.5 on a mini.

turpentine Posted July 2, 2007 Share Posted July 2, 2007 Macs use EFI instead of a BIOS. http://guides.macrumors.com/EFI - about efi sorta, intel has some pretty indepth guides if you want to learn http://refit.sourceforge.net/ tool to edit some efi things. not sure if it what you want. more specifically to your problem Most modern laptops (as well as many desktops) use the Advanced Configuration and Power Management (ACPI) standard. FreeBSD supports ACPI via the ACPI Component Architecture reference implementation from Intel, as described in the acpi(4) manual page. The use of ACPI causes instabilities on some machines and it may be necessary to disable the ACPI driver, which is normally loaded via a kernel module. This may be accomplished by adding the following line to /boot/device.hints: hint.acpi.0.disabled="1" Link to comment https://www.insanelymac.com/forum/topic/55967-unable-to-find-the-driver-for-this-platform-acpi/#findComment-400167 Share on other sites More sharing options...
stevegut78 Posted July 2, 2007 Author Share Posted July 2, 2007 Thanks for the links. I think I stumbled upon this last night in my zombie state and my eyes glazed over. Can anyone else confirm that I am going down the right path? If I am, then I'll give it a shot I have installed 10.5 on an external drive now so I can at least boot in to Tiger while I futz around. And from what I've read so far, this is probably the best bet for editing /boot/device.hints... So again...Anyone else...Am I headed in the right direction??? Or could this be what I need to do? http://forum.insanelymac.com/index.php?showtopic=54884 Link to comment https://www.insanelymac.com/forum/topic/55967-unable-to-find-the-driver-for-this-platform-acpi/#findComment-400170 Share on other sites More sharing options...
