EDIT:
INSTALL WITH: Kalyway 10.5.1 DVD to install Leopard
BIOS SETTINGS: ahci enabled, execute bit enabled
Don't use software update to install 10.5.2!

THE BRAZILMAC PATCH METHOD TO INSTALL LEOPARD:
You can find a guide how to install the Retail version of Leopard here: http://forum.osx86scene.com/viewtopic.php?f=16&t=2008
(You need at least one working Tiger system installed on your PC to patch the DVD and post patch the Leopard System after the installation finished.)
The author of this guide uses a P5W DH Deluxe but the thread is filled with postings of users of other Mainboards.
So it starts to be less usefull for P5W DH Deluxe owners.
A lot of people have problems with the installation. Maybe it will help someone when i post my/others own errors during installation.
First of all i think you should use a DVD-R (not DVD+R) (but i am not 100% certain about this)
If you run the patch on a system were VirtualPC is installed on (I migrated from a G5 before): remove the Virtual PC image drivers, there is something weird going on with them and the patch script. Unfortunately i forgot the exact location of these drivers
Looks like some people didn't moved the content of the unzipped patch folder on their desktop. This will work too but you need to enter the location of the fils into the patch script then. Better place them on your Dektop to reduce work and useless hassle.
The patch script will show an error at the end ("update_prebinding: error 256") - ignore it!
Make sure the target partition is on a Master Boot Record (MBR) partitioned HD!!! For some stupid reason I forgot that and wasted some hours (MBR an option when you create a new partition table with Disk Utility)
If you run in trouble ("INSTALL FAILED Mac OS X could not be installed on your computer) during installation process then your Leopard image might be corrupt. (or you forget to customize and deselect the missing additional installation options like languages, fonts etc.)
I tried it with a self created image of my Retail DVD but always ended with an error during install. I also had a downloaded Image and this one worked fine. So there must be a little secret how to perfectly create an image of a Retail DVD that i don't know yet.
Lot of people who finished the installation and did the post patch end up with a non booting system. This is because creating the boot loader didn't worked or the MBR is f*** up! They end with a black screen and a blinking white cursor in the upper left corner.
There are two ways to fix that problem:
1st solution:
Install a second 10.4 System on your desired Leopard Partition before installing Leopard. This way you will create a working boot loader.
Don't install other Languages etc. with this Tiger installer!!! (Leo wants to update them later and would not be able to find them on the patched installer DVD).
Don't forget to boot into this new tiger system and create a user before you start the Leopard installation!!!
Install Leopard as an update without erasing the new Tiger partition!
Run the post installation patch from your normal Tiger System and boot to Leopard.
2nd solution:
Set your Leopard Partition to "active" and create a Boot Loader. This is the way to create/repair MBR and boot loader after you do the Post-Installation Patch. This is how to do it:
Step one:
1. Boot to Tiger
Step two:
1.
- Download "Startupfiletool" - it can be found in this thread http://forum.insanelymac.com/index.php?sho...mp;#entry166040
2.
- Unstuff and place "Startupfiletool" in "usr/sbin"
the easiest way to do this is to press shift-cmd-g in Finder and enter "/usr/sbin" - then drag the "Startupfiletool" into the "sbin" folder
3.
- Locate and open the folder "files" on your Desktop (it's one of the folders from BrazilMAC's patch folder) - inside "files" is a folder called "i386" - open it.
- press shift-cmd-g in Finder and enter "/usr/standalone/i386" then drag all files from the first opened "i386" folder (the one on desktop/files) into the "i386" folder
4. I'm not 100% certain of tis, but I believe you may also need to put
"bless" into "usr/bin" (it can be found in the patch files on "desktop/files/")
Step three:
1. Open Terminal
2.
- Type: "diskutil list"
result will show all your partitions
- Write down volume name and disk identifier info!
Example:
name: Leopard
identifier: disk1s2 (1=disk number 2=partition number)
I will use "disk1s2" (or "rdisk1s2") and "Leopard " in this guide code! - exchange it to your correct numbers and name when you see type in the code!!!
Step four:
1. Mark the partition active
- Type: "sudo fdisk -e /dev/rdisk1"
(exchange "rdisk1" to your correct disk number!)
- enter your password
- Type: "update"
- Type: "f 2"
(exchange "f 2" to your correct partition number)
- Type: "w"
answer the question with "y"
- Type "q"
Step five:
- Type: "diskutil unmount /Volumes/Leopard"
(exchange "Leopard" for the correct name of your Leopard partition!)
- Type: "sudo dd if=/usr/standalone/i386/boot1h of=/dev/rdisk1s2 bs=512 count=1"
(exchange "rdisk1s2" for your correct disk and partition number!)
- Type: "sudo startupfiletool /dev/rdisk1s2 /usr/standalone/i386/boot"
(exchange "rdisk1s2" for your correct disk and partition number!)
- Type: "sudo bless -device /dev/disk1s2 -setBoot -verbose"
(exchange "disk1s2" for your correct disk and partition number!)
- Type: "diskutil mount /dev/disk1s2"
(exchange "disk1s2" for your correct disk and partition number!)
- Type: "bless -mount /Volumes/Leopard -setBoot -verbose"
(exchange "Leopard" for the correct name of your Leopard partition!)
You may get an error "Could not find IODeviceTree:/options" but it works!
Step six:
Boot Leopard
i just lost my sound while working in the old imovie 
... maybe someone could just give 
or check my list if i deleted anything else that
oh man 
) its the a back up of a hard drive after installation is compleet .
