well, the processor is a non issue.
the way i would do it:
2 hard drivers (to avoid partions and what not)
1. install win2k server (why would anyone do this is beyond me ) on the 1st hard drive
2. install linux on the second drive putting grub or lilo on the bootsector allowing it to be your main bootloader.
i dont dual boot so i dont have an example config file for grub or lilo but im sure someone does or you can google for some exmples.
