write_part_mac is probably APM, and pdisk is definitely APM. This hasn't been 
used for OS X boot disks since PowerPC/OpenFirmware. While the Apple EFI 
firmware can read and boot from APM, MBR, and GPT schemes, in practice it's 
only GPT. For a Hakintosh it depends on whether you're using UEFI or BIOS 
firmware and the size of the drive. If UEFI or a disk larger than 2.2TB, use 
GPT. If BIOS,  use MBR. I say that because you seem to be also using or trying 
to use Windows on the same computer/drive? Windows on BIOS hardware will only 
boot from an MBR disk. Windows on UEFI hardware will only boot from a GPT disk. 
OS X will boot from either.

Again this type of partition scheme hasn't been used in a long time, unless 
this is somehow specific to Hackintoshes.
