Anyone Successfully Installed Windows 2000 On Mac Pro? in Windows 2000/2003/NT4 Posted July 14, 2017 · Edited July 14, 2017 by eksu I ran into the same issue with my Windows 2000 iMac install. BWC I think documented it first with a Mac Mini -- the Bios emulation provided by Apple doesn't work with any multi processor HALs, and the XP HAL isn't as functional -- some tasks performed by the HAL in 2000 are instead offloaded to other parts of the system in XP. You might be better off trying to hack on the Mac legacy bios. Maybe if you can get Coreboot running on your Mac, then you can boot through that.
