I would suggest you to print this Tutorial to access the information when the computer reboots.

What you need:

1. SnowOSX Universal 10.6 v3.5 pc distro (get it from the bay of the pirates and burn it on a DVD)

2. iaslMe to fix the CMOS-Reset problem

 

Whats to do:

1. BIOS configuration

- Go to BIOS (hit Delete key on boot)

- Select "Integrated Peripherals" and press enter

- Select "SATA AHCI Mode" and press enter

- Choose "AHCI" and press enter

- Select "Save & Exit Setup" and press enter twice

 

2. SnowOSX Installation

- Insert your SnowOSX DVD

- Hit F12 key on boot, the boot medium selection appears

- Select CD-ROM (or DVD-ROM)

Now the setup will boot up

- Format your hard drive with Disk Utility (Utilities -> Disk Utility) to one GUID partition

- Select your hard drive as installation medium

- Click "Customize" before installing

- Select everything except of the PS/2 drivers

- Click "Done"

- Click "Install"

After the setup has finished, click on restart.

 

3. Deleting the NVDAResman.kext

- Boot again with your DVD

- Open Terminal (Utilities -> Terminal)

Enter the following commands:

cd /
cd /System/Library/Extensions/
rm /NVDAResman.kext

 

4. Fixing the BIOS reset problem

- Now press F12 again on boot

- Boot from your OSX HD (Hard Drives -> Your Hard Drive)

If Chameleon asks for "Press any key to enter boot options" boot with the flags "-v -f" (without quotes

- Copy the iaslMe.app to the desktop

- Drag your dsdt.aml, which is placed on the root of your hard drive, and drop it over the iaslMe Application

- Open the file in the folder called "dsdt.dsl" with TextEdit

- Search for "Device (RTC)" (without quotes)

- Change it this way:

Device (RTC)
{
Name (_HID, EisaId ("PNP0B00"))
Name (_CRS, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x00, // Alignment
0x04, // This is the line you have to change to "0x02"
)
})
}

- Save the file

- Now Drag & Drop the saved file on your iaslMe again

- A new file called "dsdt.aml" should be there

- Copy this file to the root of your hard drive and replace the old one
