GothGargoyle Posted August 31, 2009 Share Posted August 31, 2009 Hi. I've tried following the guide on my machine (a Pentium D box), which incidentally works fine on Mac OS X 10.5.8. I get the following error whenever I try to start up (using -v -f): I am using Chameleon rc 2.640 with the replaced boot file. I have the following Extensions in the Extras/Extensions folder of my EFI partition: AppleRTC.kext OpenHaltRestart.kext dsmos.kext NullCPUPowerManagement.kext PlatformUUID.kext fakesmc.kext I also have a dsdt.aml in the root of my drive. I am using the mach_kernel.test7 kernel. Whatever I try I can't avoid the error shown above. It seems to be choking on AppleACPIPCI every time. The error only shows up for a few seconds and then the machine turns off. When I restart the CMOS checksum is invalid and I have to set my BIOS settings back from default. Any suggestions?

GothGargoyle Posted September 2, 2009 Author Share Posted September 2, 2009 Well I seem to have got past the DSDT and AppleACPIPCI issues, but it still shuts down. The issue seems to be this: /dev/disk1s4: Can't initialize disk cache I have tried booting into single user mode and it gives me the same error if I try to run fsck manually. If I boot into Leopard it can run fsck_hfs -f over that that volume without an error. Screenshot: Link to comment Share on other sites More sharing options...
GothGargoyle Posted September 11, 2009 Author Share Posted September 11, 2009 The issue seems to be this: /dev/disk1s4: Can't initialize disk cache Adding maxmem=4096 to my boot parameters resolves this issue. I suspect the modbin kernel doesn't support >4Gb too well. Hopefully when a sources patched kernel comes out for older/non-intel CPUs this problem won't be present.

gabeoravitz Posted November 9, 2009 Share Posted November 9, 2009 Have you gotten 10.6.x working properly on this machine? I ask because I have a similar issue. It won't boot, and when i try to, it resets my BIOS to defaults. Leopard works flawlessly on this machine. If you got it to work, what did you do to get it to stop resetting the BIOS?
