an existing system that


Working perfectly with:
Iatkos L2 upgraded to 10.7.5 online.
P5KPL-AM
3Ghz Core2-Duo
4G DDR2
Geforce 8400 (too old)

when added an Nvidia GTX 550 Ti
I boot at [PCI CONFIGURATION]
and stop but worked with 10.5.6i
before!

is there a fix for this?
on OX86 HCL it is shown to have good result with 10.7.x



-----------------------------------------------------------------------------------

In case I mees up the installation, can time machine create a backup
of the whole image to retreive at a later time? and boot with the DVD and restore?
still new at this OSX86.

Thanks.

In addition to the above, remove everything related to your old card, EFI string, edits in kexts etc.
