MSI P45 Platinum odd install problem please HELP!

[Tombuddy]

I'm am a pretty experienced OSX86 user I have had several successful installs on various hardware, but I am really running into an odd problem here that I have not run into before.

 

Before we get started a little info on my system

 

Mobo: MSI P45 Platinum

CPU: Core 2 E8400

Sata DVD Burner

2x WD SATA drives

ATI X1900 Pro

4GB DDR 2 1066

 

Using various distros (iDeneb 1.3, iATKOS 5i, Jas 10.5.4) I was able boot into the installer without a problem and open disk utility. This is where the problem lies for me. In disk utility I can see both of my sata drives, and my USB external but once I try to format any of them the system will just hang on "Preparing to erase disk".

 

I have tried everything, repartitioning the drives, using the erasing USB drive to avoid the JMicron controller, but every time its the same "Preparing to erase disk", and then I have to just hold down the power to run the machine off, and nothing was touched on the drive.

 

I have read on the forum about a modified Bios for some other P45 boards? Do I need this, I figured since the DVD boots successfully, that I don't but I may be wrong ....

 

help would be greatly appreciated I need to get my recording studio back up and running!

 

Thanks in advance this forum has always been a godsend
