Ok then, a long story short i had a kalyway leopard install dual booting with XP a while ago, it had many problems so for a while i just left it. I eventually got an SL upgrade disc (legally) and after a little of trial and error have it working basically, pretty sure i made up my own method to get there as well, but thtat doesn't matter...

anyway, i have grub as a bootloader installed on the primary partition in windows and that links to an EFI (v10.5) in an ext3 partition, which in turn leads to the HFS+ partition and that worked for Leopard
Now that i have SL, that method no longer work and i get a kernel panic, booting in verbose the 2 things thtat cath my eye the most are 1. something about DSDT.aml (which i couldn't find in my mac anywhere and tried to make my own, but still doesn't seem to have worked) and 2. "cpu 1 has no hpet assigned to it" which is at the point i think it panics, this is the same for safe mode boot up i think

The only way i can boot into it is by booting into the RebelEFI CD, and then choosing Mac from there, which i don't want to do as the disc must always be into do this, so i need help with the following things:

1. ability to boot using my normal method

2. fixing the sound (Realtek chipset)

3. Installing graphics drivers (nVidia 9500GT 1GB)

4. if i leave SL running by itself for a long time, the keyboard and mouse stop responding and i have to restart, how do i fix this?

there are probably more, i just can't remember them right now but i will add them when i remember
the last big probelm i have it that every time i boot up now, at POST it says "CMOS checksum error - defaults loaded"
it says this even after they have been loaded before, and i just can't figure it out

I would appreciate any help with this, thanks! If there are any details needed or questions please just ask and i will answer to the best of my ability

SPECS:
Gigabyte 8I945GZME-RH Motherboard
Intel Core 2 Duo E6400
nVidia Geforce 9500GT
Realtek HD sound Chipset

EDIT: i have a trial of macdrive installed on windows for a few days if that can help, thanks!

come on! anyone please?!

I must say that mentioning 'Rebel EFI' (it's not really EFI) didn't garner any favour when I read your post when you first posted, but, here goes.

1. Booting: Install chameleon. Boot using whichever method works for you to boot into the OS, then go to http://chameleon.osx86.hu , and download the binary tarball of chameleon. follow the command line instructions (for simplicities sake, posted below)

If SL is installed on a GPT (GUID Partition Table), on the first partition (that you can see, not including the hidden EFI partition) then these steps are applicable. cd into the i386 directory of the downloaded chameleon folder and type the following.



on a side note, this kext: ElliotForceLegacyRTC.kext will fix your CMOS reset issues, which are covered widely in DSDT patching tutorials btw.. moving on..


2. Audio:

VoodooHDA, and don't install it to /Extra/Extensions/ unless you're moving all of its dependencies there as well, install it to /System/Library/Extensions/ and don't use some silly GUI tool to install it for you, install it the proper way.

Drag it to /System/Library/Extensions/ , authenticate, then:


in the terminal, that is the proper way to repair permissions to /System/Library/Extensions/ and regenerate the .mkext.

If it kernel panics on you (VoodooHDA) which it does with some people, boot with either -s or -x and remove it, and remake the .mkext again, then reboot, report back either way.

3. Graphics: I have an nvidia 9500GT 1GB myself.. just install nvenabler, as long as you confirm your device id/vendor id combo are in NVDAResman.kext/NVDANV50Hal.kext as per the nvidia walkthrough. NVenabler one can be installed to /Extra/Extensions/ if necessary, the same commands will work for installing to /Extra/Extensions/ as from /System/Library/Extensions/



4. PS/2? USB? What about the mouse? You should be using USB for both, if you mix & match or use only PS/2 then weird issues always happen, Macs don't use PS/2 so all the drivers for them are hacked and patched together by OSx86 devs.

thanks so much for your help, i will try out your suggestions ASAP and report back

thanks again!
