An engineer from Apple Computer pointed out that we should not put much hope on easily running Windows on Intel Mac.

Although the Mac fans have been hoping that the incoming Windows Vista would be able to run on a Mac easier than the Windows XP, since Vista will be introducing the support of EFI (Extensible Firmware Interface) besides the normal BIOS support, Apple Senior Software Architect Cameron Esfahani said he only know that the EFI will be present only in 64-bit versions of the Windows Vista. However, the current Intel Macs are all equipped with 32-bit Intel CPUs. Also, he pointed out that the implementation of Mac's EFI doesn't have much legacy support for the Windows system.

Apple won't stop users from trying to run Windows on Macs, but users should not put any hope on Apple's support on this. And on the other hand, Microsoft has stated that the initial release of the Windows Vista won't have EFI support at all.
