Hello,

Honestly it can be very easy, and I used no DSDT (I tried but I can't get them to compile to an .aml again after I extract them) I have the latest A14 bios on both machines. I will lay out what I think is the quickest and easiest way to succeed (I recently set up another one and have settled on this method here) First go to:

http://www.osx86.net...do=file&id=3275

And grab -

1. 2 Partition USB method.zip

You also need a USB stick of at least 8 Gb's

And best to have a USB keyboard and USB mouse handy (I really needed these)

Once you can successfully make a USB installer the rest is pretty easy:

Step one - Partition the USB stick into 2 partitions, the 1st a small 250Mg one named BOOT and the 2nd all the rest of the space named INS_LEO (names not important)

Step two - restore the boot image partition (from the zip file) to the BOOT partition on the USB stick (it is in the 2 Partition USB method.zip from the link above)

Step three - follow the instructions to make the INS_LEO Partition with a Lion installer image (that you must have) insert the replacement kexts into the system/library/extensions folder (just delete the ones that are there first then put these in their place)

You now have a stick that will boot an M6300 and it has the 2 most important kexts that you need to replace after the install to get it booting

If you plan on having WiFi and want the best easy solution buy an Apple BCM94321MC

I am using 3 of those cards, 2 in my M6300's and one in my desktop with an adaptor (get  s:l:e kexts.zip from the link above and there is an IO80211Family kext for this card in there) all 3 work well and have no problems getting to the App Store (these cards can be bought used for around $10)

Boot the USB installer, choose a language, go to disk utilities and partition your hard drive with at least 2 equal size partitions (I chose 50 gigs each but it is up to you) I also made a 3rd partition of about 200 gigs to store image files and software

Perform the install onto the first partition - when the install is done do not restart! choose to open a terminal instead - from there you can replace the IOPCIFamily.kext & AppleACPIPlatform.kext

These are the only unix commands needed:

ls   list contents
cd navigate
pwd Display absolute path to present working directory.
rm -rf DIRECTORY    Same as rm -r but without asking for confirmations.
cp -rf DIR NEWDIR Copy DIR and all its contents to NEWDIR.

you need to navigate to /volumes/  and use ls to see all your drives including the Lion USB installer partition

if you named your new install something like OSX_01 (for example only, name whatever you like) then the remove commands will go something like this:

rm -rf /volumes/OSX_01/system/library/extensions/IOPCIFamily.kext

rm -rf /volumes/OSX_01/system/library/extensions/AppleACPIPlatform.kext

and if you named your USB Lion installer partition something like INS_LEO for example the copy commands go something like:

cp -rf /volumes/INS_LEO/system/library/extensions/IOPCIFamily.kext /volumes/OSX_01/system/library/extensions/

cp -rf /volumes/INS_LEO/system/library/extensions/AppleACPIPlatform.kext /volumes/OSX_01/system/library/extensions/
  
There may be typos so have a list of basic unix commands handy, pwd is handy as you can navigate deep and then enter pwd and get the entire path and copy it so you can paste it (less typing that way)

You can do the same for the WiFi kext at this point too if that is the route chosen.

Now you can quit the terminal and click the reboot button and boot, then F12 choose USB then when Chameleon starts up again choose the new Lion install partition and type these boot flags:

arch=i386 -f -v

That should boot the install where you can RUN multi beast & install easy beast so you don't need the USB to boot (TIP - once to the desktop eject the usb)

I did exactly this and all went perfect, I only have LION 10.7.0 so after I did this I rebooted to make sure it was working then I used the USB stick to reboot the installer where I used Disk utilities to make an image file of the new install before I messed it up, I then restore the image to my 2nd partition to have two working installs I could boot (in case I mess one up also)

After that it gets a little tricky to upgrade all the way to 10.7.5

I then booted to the Hard Drive and chose the 2nd partition and upgraded to 10.7.4 but before I rebooted I replaced all 3 kexts (I used the 3 from my s:l:e kexts.zip) again because the upgrades mess up the install if you do not. I also kept track of a few other kexts that I rolled back which I believe are - IONDRVSupport.kext AppleBacklightExpert.kext IOGraphicsFamily.kext AudioAUUC.kext (you may want to copy the S/L/Extensions folder to the desktop or spare partition after you get the first Install booting, then you can compare and roll back from there)

I rolled back all 7 kexts I have now listed each time I ran an upgrade before rebooting (not sure if all needed this but I had no issues this way)

Once I finally had it to 10.7.5 I was able to get it to boot without the added boot flags and run at 64bit mode - I will attach my final org.chameleon.Boot.plist

It may take a few tries - Best of luck!
