How can i integrate both 32bt and 64 bit XP on the same disc?

To create 32 bit multi boot dvd seems easy enough to follow, but i've been reading that x64 OS is different. Is there a guide i follow that will solve this?

I am interested in doing the same. I have a xp pro VOL licence cd with MCE 2005 integrated, and would like to know how to make a multi-boot dvd that would have XP x64 as well. Any help is appreciated.

Take a look at this pinned topic:

Once the modification is done, you can integrate the 64-bt version just like a regular 32-Bit OS
