Mountain Lion Hangs on White screen during install

[Adrian B]

Well...I think the only thing that isn't working is my PS/2 keyboard. I have a Logitech keyboard that I like but that is PS/2. I have been using a usb one, but I mistype a lot as as a lot of letters are worn off because my wife used it up. Hopefully I can get this solved soon so I can hook my Win 7 drive back up and make sure it dual boots fine.

When I set the media card reader as "CD" in BIOS the errors on boot went away.

Many thanks to PJALM and Totenkopf4 for all the help.

If I have missed you trying this, then I do apologise. There is a PS/2 keyboard/mouse option in MultiBeast under Drivers & Bootloaders > Miscellaneous

Adrian,

Thanks, yes I have tried it. Several times in fact. Had it selected with a couple other things, and also have tried it by itself, too. Some research leads me to believe that I need to uninstall PS/2 mouse and trackpad kexts but I have not found them. OSx is much less intuitive to me compared to Windows. I will as PJALM in chat when I get home from church, as I sure it is probably something he knows and is probably simple. He is a Wiz.

Thanks.

PJ said he preferred VoodooPS2 so I will look into this when I get home.

I have decided not to bother with the PS/2. My wife can use a usb keyboard when she wants to boot my computer to OSx (I did this for her. She needs access to iTunes Producer).

I think I am going to consider this done. Everything works except the PS/2 keyboard. Sleep works, sound, media card, dvd all good.

I am ready to put my Win 7 drive back in and set it as my primary drive.

Thanks again to PJALM, Totenkopf4 and Going Bald for their contributions.

Complete!

I can boot directly to Windows 7 or if I hit F8 on boot I can select my OSx HDD drive and get directly into Mountain Lion. And everything works!

Thank you again!

Hi,

I have the same mobo, I've been running it without DSDT since now.

What bios version do you use? I remember updating my bios ince, but that gave me alot of problems.

What are the benefits of using a DSDT vs. just Chameleon/chimera?

 

[miztrniceguy]

Bios version was 1606 x64 8/16/2012, but then I downloaded the most recent one. Modded it using PMPatch, and modified DSDT using PJALM's Patch repository and MACiASL.

Colorfuel,

If I want to boot to Mountain Lion all I do is select F8 and it boots directly to Mountain Lion without any input.

Prior to patching I had to type -v -x PCIRootUID=0 GraphicsEnabler=No to boot to ML.

I have Win7 on SSD with a 500 GB for storage, OSx ML on SATA WD 160 GB and am running 16GB of Corsair Vengeance 1866 MHz ram. Also have a media card reader and a SATA DVD writer (Asus) and everything works.
