More on Booting Windows on the Intel Mac?
Many believe that booting Windows on the new Intel Macs will become an eventuality, and the efforts are ongoing...
OpenOSX announced they are achieving "nearly native" performance on Intel Macs with OpenOSX WinTel 2.0 - a PC emulator. This appears to be a re-brand of the open source Bochs emulation project. This sort of commercialization has been met with some controversy. User experience with this particular product is limited at this stage, but one comment claimed "It does seem to be working, but I am pretty positive that it is working nowhere near native speeds on this brand new Intel iMac."
Meanwhile, one user reports on his experience booting into the EFI menu on an Intel Mac. This is of limited use at the moment, and of course, proceed at your own risk.
