Speaking at Intel Developer Forum in San Francisco, Microsoft development manager, Andrew Ritz said that the same will apply for those wanting to support for booting Windows via EFI on systems with 32-bit processors.
Ritz said that the first time you will see EFI support will be the release of Longhorn Server and goodness knows when that will show up, he said.
The move will prevent owners of the new MacInteltoshes from running a dual boot on their machines. Not only would they depend on EFI, their processors are not 64-bit and will not work anyway. This will mean that they will be forever stuck with OS X and dual booting earlier versions of Windows.
Vole's main reason dumping the EFI booting was because there was it wanted to drive a move to 64-bit computing, Ritz said. µ
