[SUCCESS] ThriftyMac - HP dc7900 - £100 - 10.9.4 Mavericks

[P1LGRIM]

can't seem to get it to boot for some reason starts booting from UniBeast pen drive then all of a sudden it reboots back to the bios screen any ideas? I've booted with -v -x -f and still the same

Sorry, not really enough info to draw any conclusion.

Is it stable in Windows / any other Operating System ?

BIOS upgrade ?

Reduce to minimum configuration ? CPU with one stick of RAM and HDD

Try Unibeast flash drive in other USB port(s)

What's the last thing you see before reboot ?

Good Luck

how did the install go?

Sweet as a nut - But it was already running the Yosemite Beta so I actually upgraded it through the App Store.

Server doesn't run yet - Needs a new version for Yosemite.

Procedure to upgrade this build to OS X 10.10 Yosemite

Read the Upgrade Guide.
Prepare your Unibeast flash drive as per the guide.
Make a Utilities folder on the flash drive and copy your favourite utilities to it - i.e. Multibeast.

Backup your existing Mavericks hard drive with Time Machine or your preferred backup solution.
Clone the Mavericks hard drive to another - I use Carbon Copy Cloner.
Install Chimera to the clone.
Shutdown, remove the original Mavericks hard drive and boot with the clone to prove it works.

At this point decide if you want to install Yosemite to your original drive or your clone.
Boot your chosen drive.
Delete /Extra/modules/FileNVRAM.dylib if present.
Delete /System/Library/Extensions/GenericUSBXHCI.kext if present.
Edit /Extra/org.chameleon.Boot.plist to remove the following 2 lines if present:

<key>Kernel</key>
<string>mach_kernel</string>

Insert your Unibeast flash drive.
In order to edit some hidden files on your Unibeast flash drive open Terminal :

sudo chflags -R nohidden /Volumes/NAME/System
sudo chflags -R nohidden /Volumes/NAME/Extra

Note : Replace NAME with the name of your Unibeast flash drive.

On your Unibeast flash drive edit /Extra/org.chameleon.Boot.plist to include selections from the same file on your hard drive.
ie GraphicsEnabler and IGPEnabler
Replace the /Extra/smbios.plist on your Unibeast flash drive with the /Extra/smbios.plist from your hard drive.
Shutdown

Power on and press f9 for the boot menu.
Select your Unibeast flash drive with the arrow keys then press the spacebar
Type -v -x -f and press return.
Install Yosemite without formatting the hard drive.
When the system restarts press f9 for the boot menu but this time select your hard drive with the cursor keys
Type -v -x -f and press return.
When you arrive at the desktop navigate to /System/Library/Extensions
Move AppleHPET.kext to the Trash.

Open the Utilities folder on your Unibeast flash drive and run Multibeast.

/Extra/org.chameleon.Boot.plist

	<key>EthernetBuiltIn</key>
	<string>Yes</string>
	<key>GraphicsEnabler</key>
        <string>Yes</string>
        <key>IGPEnabler</key>
        <string>No</string>
	<key>Kernel Flags</key>
	<string>kext-dev-mode=1</string>
	<key>Legacy Logo</key>
	<string>Yes</string>
	<key>Timeout</key>
	<string>2</string>
        <key>Graphics Mode</key>
        <string>"1920x1080x32"</string>
	<key>UseKernelCache</key>
	<string>No</string>

Shutdown, remove your Unibeast flash drive and power on your Yosemite system.

Note : Server needs an upgrade to version 4.0 to run on Yosemite - Available in the App Store.
