I am not sure if this is doable. I received my Snow Leopard CD, but not sure what to do with it... I have read that the P5K-E is a supported motherboard, but have also read that one should install on dedicated hard drive. Currently I don't have a dedicated hard drive. I was hoping to just create a partition on the same drive that windows is on. Advice?
Thanks!
Not possible - XP is on an MBR formatted drive and OS X requires GPT+ formatted drive.
See
http://www.tonymacx86.com/threads/guide-multibooting-for-the-novice-updated-3-12-see-log.18658/ - scroll down past installing Ubuntu to the OS X and Windows XP section.
It is possible, installing from scratch, to have both on the same drive IIRC, but it has been so long I really do not remember the exact procedure. It should go something like this:
Boot to BIOS and set the ODD to first device in boot order.
Boot with iBoot in the ODD
Swap iBoot for SL 10.6.3 install DVD, wait for drive activity to stop, hit F5 to refresh the screen
Select the OS X DVD icon and hit enter - note you might need some boot flags here
At the install screen, format the HDD 2 partitions, first partition Mac OS Extended (Journaled) with GUID partition tables (click the option button to check/set this), second partition MSDOS FAT (this creates a hybrid GPT/MBR partition so Windows will install on it)
Install OS X and get it working and booting from the HDD. Put the WinXP install DVD in the ODD and reboot to BIOS.
Reset the SATA mode to IDE because XP has no support for AHCI out of the box - add the drivers later. Save&exit and continue boot.
Install WinXP on the second partition. Download and install Service Pack 3 and the AHCI drivers.
Boot to BIOS again and reset the SATA mode to AHCI so OS X will work.
This is a lot of trouble to go through for an obsolete OS like WinXP and SP3 & AHCI drivers may be impossible to find.
