I have a old Dell XPS 410, I was run 10.7.5 and with many attempt to run 10.8. I got great news as it works in 10.8.3 for me, I learn form many sources I will give credit to the place I learn.

my hardware specific
you need to downgrade bios to 1.3
Cpu core2duo 6300 1.8 ghz
Ram 3 Gb : 2x1GB, 2x512 Mb
Graphic card Nvidia PNY 9800 gtx+
hard drive 1TB.
you need MountainLion app fromt he app store 10.8 or 10.8.3
first you create an usb installer like 8 GB at least and follow this guide credit to Still Win Fan
the same for mountain lion. when you done the usb installer.
then you install extra folder to that usb installer from myhack from Conti
we need to prepare some thing like this for it to able to boot into 10.8 install srceen is put on PciRoot=4 because this guide credit go to oldnapalm
used text edit to edit org.chameleon.Boot.plist for the PciRoot=4
used chameleon wizard to create a SMBios and place it in extra folder.
for the ATA drive to be recognize need kext IOATAFamily.kext from
run myfix from myhack.
it is ready to install now.
after install success get to desktop then run combo update to 10.8.3 the the rest for you to enjoy you hack
I have it running Maverick, this time I found a easy way to tunning to a workable machine, this time I have the graphics to nvidia GT 610 which have a audio over HDMI with voodoo HDA 2.8.2
i have attack the extra filer from my machine, when you created usb installer, I recommend MyHack, then use my hack to install this extra folder to USB installer, this way will help your tune the machine easy. follow the installation to the end, it may not be finish but it is ok. boot up with the usb installer again, don't install, go to utility and then Myhack, then install extra folder from download, done and reboot and enjoy the machine.
