changed hardware - HD 3870 not running

[zuz242]

as i had a perfect running system, i had to "upgrade" my graphics

my former gforce 8600gt ran "out of the box", my new ati hd 3870 doesn´t..

i tried installing (on an eternal hdd this time) both zeph 10.5.2 and leo4all with ati 3780 support
ticked but to no avail.

so i wonder how:

1. get osx to boot at all, basic vesa graphics (only tried install without any gfx drivers, -x bootup)
2. fixing / installing ati driver for my sapphire HD 3870 ultimate (passive card, not based on reference
layout). maybe different device id?

thanks in advance

not yet, as i need to get into osx (part 1.) first.

but i´m getting to 1. after booting with -s an deleting ati..2000.kext i seem to be
able to finish install and boot into osx. (but i messed up with account creation it seems,
so i have to install again...)

macdrive is messing with my xp sys without granting access to osx partitions. is this normal?

btw. device id is 0x9511002

still on it

installing with zephs release and ticking (the fitst?) two ati drivers gives me
a "garbled screen" at boot.
now im using -x to get into the system. here i get told that natit.kext is not installed
properly and gfx is vesa only

could anybody give me a clue how to proceed? i installed the driver package mentioned
above, using pacifist with overwriting all files as i read a normal install sometimes leaves
old files in place ..

is there anything i could do with my device id? in ARTIRadeonX2000.kext it is included,
in Natit it isn´t ...

thanks

{EDIT}
after installing another driver (eddies this time), i got an instant reboot again.
killed all ATI kext and natit, got basic vesa gfx again ...

I finally got a fully working osx install again!
The problem resided in the hardware, specific the motherboard chipset.
After i changed from a Nforce board to a Gigabyte with AMD 790X,
everything is fine.
