Hello to All,
I am newbie here want to install ML on my Intel Desktop Motherboard DG41RQ Processor= core 2 Quad 2.6Ghz, RAM=4GB, Graphic Card is ATI Radeon HD 5450. I am using USB created with Multibeast 5.2 things went wrong when I pluged the ATI Radeon HD 5450 Graphic Crad. It stuck on boot with teh message "Pci Configuration Begin" I've tried multiple switches e.g.. PCIRootUID=1,GraphicsEnabler=NO,YES, Boot Verbos Mode and Safe mode blah blah, if I remove the card and run the pc with builtin graphic which G41 Chipset and GMA 4500 it runs fine but there is no driver for this VGA( Atleast I could not Find on the net).
My BIOS configuration is Core Multiplex Tech = Enable, MAX CPUID Value Limit=Disable, Drive Configuration = Legacy Sata Only, PCI Latency Timer =32 ,HPET=Enable, UEFI=Enable XD Tech= Enable, Intel VT=Enable.
Please help me to install Mountain Lion on my Mobo with that ATI Radeon HD 5450 card.

and my reply for it....
Thanks for your response! alespardo
my problem is that my system stuck while installation I've tried many switches but screen freeze at this point...
IOPIC:Version 0x20 Vectors 64:87
ACPI:System State [s0 s3 s4 s5] (S3)
PFM64 (36 cpu) 0xf10000000, 0xf0000000
[pci configuration begin]
I googled and found many tweaks one of them which change or add one line to above is ....
-v -x npci=0x2000 pci-off busratio=20
it add extra line "resolution 1024 x 768 @f00000" to above
NOTE: I can easily install Mountain Line after removing Graphic Card which is ATI Radeon HD5450 and thanks for sharing the driver(kext) link I've already found it on the net by google. so problem occure when I plug the Graphic card I don't know but there must be solution e.g..a switch or bios setting or tweak for it thats what I am asking and searching for.
Thanks ...
Now please your term to help me out.....
