Windows XP incompatible with Mactels

updated 11:45 am EST, Thu January 12, 2006

Mactels can\'t run XP

Looking forward to Intel-based Macs, many hoped that they would be ableo Windows XP and Mac OS X. However this is not the case, according to a report from BetaNews. The report says that Apple's use of the extensible firmware interface (EFI) rather than BIOS, current Windows releases will not run on the new Macs. Limitations in Windows itself will prevent its use on the new Macs, and Apple's vice president of worldwide product marketing Phil Schiller said the company would not specifically block the use of Windows on Mac hardware.

Apple's move to Intel processors also meant a switch from Open Firmware to EFI, which is an updated BIOS specification developed by Intel. Advanced EFI offers the ability to boot into an EFI shell to run diagnostics and power up the CPU into a fully functional state immediately. EFI also separates the control of devices from the operating system, allowing it to initialize hardware prior to loading the operating system. This feature allows a system to connect to the internet to download updated drivers before booting up, according to the report.

Microsoft has plans to add EFI support to 32-bit versions of its new Windows Vista operating system, but the final release isn't expected until the end of 2006. Additionally, Microsoft's 64-bit versions of Windows are incompatible with the new Intel-based Macs despite supporting EFI, due to Apple's 32-bit-only Intel platform.

Microsoft on Tuesday announced a formal five-year commitment to develop its Office product for the Mac--offering support for PowerPC Macs as well as Intel-based machines.

    Admittedly....

    ...it would be nice to be ABLE to boot Windows. BUT, the positive is that the performance increases from the new Intel chips should far outweigh any negative this story carries. Even so, it will be possible by this winter. Who knows how good Virtual PC will become now that x86 emulation is out of the mix. Also the x86 version of Darwine is coming along...it's not a perfect world, but it's heading there.

    market share

    Most people I know have essential apps on the pc side - everyone is talking about macs - letting me boot windoze would let me sell my pc & upgrade my mac - as it is I'll keep both - making the wintel macs essentially 2 in 1 computers would add more value than doubling the speed - the other 95% of computer users would then have the option of buying a mac - seems like a no brainer to me...

    I may even sell my shares...

    Vista

    Vista will boot on EFI if I am not mistaken.

    Wooahh!

    Did I read correctly that the MacIntel's are "32-Bit only". h***'s Bells, that's one step forward and two steps back. Further proof that gains in processing power are being eroded by limitations of software, or should I say "bloatware"! Of course Apple was always disingenuous in it's marketing of OSX as 64-Bit, as anything that ran with a GUI was always only 32-Bit given that only apps run from the terminal could run in 64-bit. Not to mention that bugger-all apps ever had full dual-processor support either. So dual-processor supposedly 64-bit machines were always less than the sum of their parts. Like a V8 that would only allow you to use four of the cylinders! Sheesh!

    May not be entirely true

    If I remember correctly some of the latest PC's from Gateway ship with the EFI firmware, and they have Windows Media Center installed on them. I believe the EFI has the ability to emulate a standard PC bios just for this sort of problem.

    Gateway uses EFI ??

    Gateway started shipping PCs with EFI and running Windows XP back in November of 2003. The story at the URL below also says that Microsoft wil start promoting EFI. Something doesn't smell right about this story Windows not being able to use EFI.

    RE: wooahh!

    please be aware that being 64-bit does not increase performance per se. Instead it allows you to address larger amounts of RAM and be able to calculate larger numbers without having to use floating point math.

    As the iMac and the new MacBook Pro aren't capable of holding 16GB+ of RAM there really isn't need for the hardware to support 64-bit.

    I could be wrong but I believe that Intel isn't making a dual-core chip that is 64-bit at this time.

    Incorrect feathers!

    The MacIntel's are starting out with a 32-bit version of 10.4.4 for now. That doesn't mean that they are 32 bit, and I highly doubt that Intel's latest and greatest processor isn't 64-bit capable.

    Most likely, Apple wanted to get Intel Macs out quickly and it was easier to start with the OS at 32-bits. Considering that most iMac and laptop users have no real need for more than 4 GB of RAM, it isn't an issue.

    latter this year

    "Vista will include support for EFI when it ships later this year, so unless someone comes out with a hack that gets XP up and running on the iMac and MacBook Pro, you'll have to wait until later this year to dual boot Windows and Mac OS X natively on the same machine."
