-k is kext repository cache
-m is mkext cache
Basically, mkext cache is used from the bootloader to help the kernel load files quicker.
kext repository cache is used by kextd to help it know which kexts to load.
The changeover happens when you see jettisoning kernel linker. Thats when kextd kicks in and uses the other cache file.

So Leopard could use Extensions.kextcache also?
The 3 caches still exist in Leopard but they are named different things now.
/System/Library/Extensions.mkext - mkext cache
/System/Library/Extensions/Caches/com.apple.kext.info - kext repository cache
/System/Library/Caches/com.apple.kernelcaches/kernelcache - kernel cache
mkext cache and kext repository cache will have noticeable impacts over boot time of the DVD and minor speed boosts for the HD install. The kernel cache I can't see having much impact but it was pretty much added for the embedded devices (its a kernel with prelinked extensions) - used in Apple TV and iPod Touch and iPhone.

kextcache -a i386 -m /Volumes/vol_name/System/Library/Extensions.mkext -v 1 /Volumes/vol_name/System/Library/Extensions/

kextcache -a i386 -l -n -s -m Extensions.mkext Extensions
With some other tricks its actually possible to get the DVD to boot in just over 2 mins.

Anyway, when isntalling is almost no necessary the network, well only if you are doing "remote installation" I presume.

hey can u please help me in getting that blue screen right after installing leopard......please reply.... iam having a compaqc755tu laptop with GMA X3100 ,GM965 chipset please help me....
Sometimes the boot process is awfully slow, so I made this file:Extensions.mkext with the following steps to avoid the slow and boring wait.You only need to install this file in your DVD Image and burn it.Intel:http://www.mediafire.com/?b1dtwhvjiqzAMD:http://www.mediafire.com/?c0ew012fbxhhere is how:Erase the Extensions folder of your DVD Image, copy this file to System/Library and burn to a DVD.You will boot faster, less wait than the "retail" patched DVDsHere is how I created it:I mounted my BrazilMAC patched image of Leopard with readwrite ability, you can do that if you rename the ISO image to .cdr suffixthen I copied the contents of the Extensions folder to my Destop.cp -R /Volumes/Mac\ OS\ X\ Install\ Disc\ x86/System/Library/Extensions Desktop/Extensionsor by opening the containing folder and dragged it to the Desktopopen /Volumes/Mac\ OS\ X\ Install\ Disc\ x86/System/Library/then I make the cache with this on Terminal:sudo kextcache -a i386 -k -z -m Desktop/Extensions.mkext Desktop/ExtensionsI erased the Extensions folder from the mounted Image with the Finder or with this command on Terminal:rm -fr /Volumes/Mac\ OS\ X\ Install\ Disc\ x86/System/Library/Extensionsthen I copied the Extensions.mkext to the System/Library folder of the mounted image with Finder or wtih this command on Terminal:cp Desktop/Extensions.mkext /Volumes/Mac\ OS\ X\ Install\ Disc\ x86/System/Library/then I repaired the owner and group:sudo chown root:wheel /Volumes/Mac\ OS\ X\ Install\ Disc\ x86/System/Library/Extensions.mkextumount the image, burned it and tested it.Other advantages is that you have a faster boot DVD in case of emergencies or if you need to a handy Disk Utility or Terminal Apps.
I am planning to do an AMD version for Prawker's method DVD and also test this one with TOH version of Intel and if the AMD version works with the ToH AMDThis could work with other patched DVDs (for Intel of course), also you can do your own Extensions.mkext, but try it with DVD RW media or you could end with a lot of coasters NOTE:I prefer to answer in this thread than by PM, if you have a question please post it here.Edit:I tested with BrazilMAC and ToH DVDs on my Dell XPS M1330.Edit2:AMD version. tested with Prawker's method and ToH with AMD ppf V2

also can you not just burn the osx86 disc to say a BD-R as it has a faster read speed of 20MB/s?, yes I have a blu ray drive so will that work?
