iAtkos 5i 10.5.5 update to 10.5.7. How?

[johnmelano]

Hello,

 

I'm trying to get full graphics acceleration in iAtkos 5i (10.5.5), which I was getting fine with my previous graphics card but now I bought a HIS Radeon 4850 1GB, and at best I can boot to the 1024x768 Vesa mode. For what I've read the 4850 doesn't work in 10.5.5 so I would need to update to either 10.5.6 or 10.5.7, so since my iAtkos installation seems very much what they would call an upgradeable system, I downloaded the 10.5.7 combo updater from Apple's website and tried updating about three times without success, at best I can boot into safe mode, but that's it. If I don't boot into safe mode at some point during the first screen with the spinning circle the screen shows a weird pattern and nothing else happens. If I boot into safe mode and I install the latest Natit drivers then after that I can't even boot into safe mode anymore.

 

For all these tryouts I started by booting up from the iAtkos 5i DVD, going into Disk Utility and setting one GUID partition in the drive designed to use Mac OS X (I don't use software multi loaders, I use the motherboard to set the boot order that I need). So all these tryouts were clean installs.

 

I read a few posts from people here that were able to do this successfully, updating with the combo updater from iAtkos 10.5.5 to 10.5.7, but after wasting so much time without success I'd rather ask for help here.

 

I'm trying to avoid downloading another 4 GB OSX86 distro, and I want to find a way to make my new Radeon 4850 work in Leopard.

 

From the iAtkos 5i DVD, the only change I made to the default install is to select the Intel AHCI SATA driver and I used -f for the first boot, since I read here that it helps.

 

Here are the rest of my specs in case it makes a difference:

 

Motherboard: Intel D975XBX2

CPU: Intel Q6700

RAM: 8 GB of OCZ Platinum DDR2

HD: W. Digital SATA-1 160 GB

Video card: HIS Radeon 4850 1 GB (Two DVI ports, one connected to an Envision 9110 monitor and the other to a Sony TV using a cable that has a DVI connector in one end and an HDMI in the other end, going through an HDMI switcher. When the switcher is not selected to the input for this cable, it's as if it wasn't connected to anything, as if the cable wasn't there)

 

Thanks
