Reinstalling Working Kernel after 10.6.7 combo update

Got an Asus M4n68t (from memory) mobo, 1tb hard drive (not sure what make), 8600gt, amd phenom II x4 645 and 8gb ram.

 

Got iatkos 10.6.3 installed and working, did combo update to 10.6.7, backed up my kernel, stupidly didn't copy my old kernel back in, and now get an ACPI kernel panic.

 

My question is - can I simply reinstall a working kernel from the dvd without overwriting everything else? My kexts are backed up and resintalling them is no problem.

Yes simply fire up the DVD , go To Terminal

 

type df -h

 

You'll see a list something like this

 

/dev/disk0s2   465Gi  266Gi  200Gi	58%	/
devfs		  110Ki  110Ki	0Bi   100%	/dev
map -hosts	   0Bi	0Bi	0Bi   100%	/net
map auto_home	0Bi	0Bi	0Bi   100%	/home
/dev/disk1s1   233Gi  110Gi  123Gi	48%	/Volumes/BOOTCAMP

 

Simply go to /Volumes/<whatever your HD name is> and just swap (use mv) the files , you should be able to swap it. Its not a big problem. The question is are you familiar with UNIX commands

 

Anyhow , the command you'll be needing is

 

mv mach_kernel mach_verybadkernel

mv youroldkernelbackupname mach_kernel

 

reboot !

 

Easier way is to use chameleon and in arguments , simply supply the patched mach kernel name (i.e patched_kernel). Two ways , your call !

Brilliant - thanks. I actually ended up using the 10.6.7 legacy kernel installer - required rebooting twice and then chameleon refreshed everything.

 

I am familiar with UNIX commands :) I'm not that n00b, it has just been a while since I installed a Hackintosh system so I am a bit rusty :)

 

Using the -force64 flag in my boot.plist has given me my 8gb ram back, and system info is reporting 1 cpu with four cores :) Looks like I am in business :)

 

Next question - any way to prevent various partitions showing up in the chameleon bootloader for selection?

Use "Hide Partition" option to hide one or more partitions. Like:

	<key>Hide Partition</key>
 <string>"Linux" "Data" "Backup"</string>

You may use disk label, device name or UUID. Please read Chameleon documentation for more.
