As suspected applehda.kext doesnt support the jacks on the optiplex755 when i booted up 10.7.5 for the first time they were not an option but it booted! By simply going into system, library and trashing the applehda.kext it allowed the voodoohda.kext to load on the next boot. So thats pretty much a working 10.7.5 on optiplex 755. Theres a complaint on boot about c states or something so the power management is probably broken but it doesn't really matter very much.

ok heres what I have done now start with 10.7.0 -> 10.7.3 added ethernet hdaaudio and nvidiaenabler kexts
if I don't have them at this point i don't get a screen when I go to 10.7.4
now I am on 10.7.4 and am upgrading to 10.7.5 I expect audio problems but i think the screen and ethernet will be ok
from googling around it looks like applehda.kext isn't compatible with hdaaudio.kext if i am right then i need to disable applehda.kext (probably just rename it and ensure hdaaudio.kext is in extensions that should cure my audio problems
thats if it boots up at all ) will get back to this thread after the upgrade. The upgrade maybe pointless as it seems 10.7.4 is actually faster but some versions of tools like xcode require 10.7.5

hmm something has gone a bit wrong
I initially went 10.7.0 10.7.3 10.7.4 10.7.5
at which point i found my only audio was hdmi.
i retraced my steps and was fine to 10.7.4
however I didn't install the nvidiaenabler.kext
and this time no display or sound.
I think it maybe the applehda.kext gets installed on 10.7.5 which is why the problem with audio
i'm kind of stuck with this unless i can get nvidiaenabler installed via my 10.7.2 partition.
maybe anyway.
I guess there should be a way to get this working from boot but honestly I haven't a clue what I'm doing

Thanks for the reply, very useful titbits.
I took a guess and formatted the first partition (copied both user directories as they hold most of the stuff downloaded to them).
The guess was right my backup had become the 10.7.2 partition.
so i've reinstalled 10.7.0 to the first partition so I can upgrade that one I hope (renamed it to firstosx) so that should become clear
thanks

ok i used myhack to create a usb install of lion 10.7.0 on a Dell optiplex 755
and i installed to the first partition on sata2
I used kextdrop to get the ethernet working along with hda sound and nvidiaenabler.kext.
I decided to upgrade to 10.7.2
because I thought this might go wrong I decided to copy my hfs+ partition with gparted in debian
sata2 now is ¦hfs+(original) ¦ ext3 data¦ freespace ¦hfs+copy¦ freespace ¦ linuxswop¦
now the 2 hfs+ partitions are near identical with same diskname.
after I made my backup copy I installed 10.7.2 update and now it gets wierd
on boot I have 3 options a penguin a lion and another lion.
if i don't choose an option osx fails to boot properly
if I choose the middle lion then it also fails to boot properly
if I choose the end lion then I boot to 10.7.2
however I don't know which partition that is the original or the copy.
now if i boot into debian from the first hdd and run gparted.
I can see the original hfs+ partition has more free space than the copy.
so any idea what I have done?
have I mistakenly upgraded my backup partition to 10.7.2 ?
why does the boot fail on the middle lion partition.
how do I fix this ?
which partition do i delete and which do I keep?
should I now copy my copy back over the original ?
i'm kind of hoping to keep going up to 10.7.5 eventually
but it failed to work when i downloaded with software update.
any suggestions please?
