Windows on Intel Macs - Yes or No? 714

Posted by Zonk from the will-they-or-won't-they dept.
With the announcement of the Intel chip based MacBook, the door is now open for running the Windows OS on Macintosh hardware, right? jaypatrick writes "BetaNews reports that along with the announcement of the first Intel based Macs yesterday, many users have rejoiced in being able to dual-boot both Mac OS X and Windows. Unfortunately, this is not the case; due to Apple's use of the extensible firmware interface (EFI) rather than BIOS, current Windows releases will not run on the systems." I guess not. But, wait... Big Z writes "Phil Schiller, Apple's senior vice-president of worldwide product marketing, said in an interview Tuesday that the company won't sell or support Windows itself, but also hasn't done anything to preclude people from loading Windows onto the machines themselves." I think someone actually trying it out is the only way this is going to get straightened out.

    When something like Linux is ported to anything, it's because there is a cult following in the community and this is what they specialize in. Window's has a cult following, it's just not specialized in this sort of development.

    The benefits of a port might be because of cheaper or easier to find hardware capable of running something that it wasn't meant to but is very useful to users. I don't think this is the case in putting Windows on an Intel Mac because Intel Macs are cheaper than what I can piece together in PC x86 form. Don't get me wrong, Macs are nice machines but they're not exactly easy to upgrade or fix on your own.

    I'm sure someone will port the extended firmware interface to run Windows through a virtual layer (if it needs it) but this can only introduce Windows running as fast or slower than the speed it could run at without EFI.

    For this reason, I doubt people are going to find much use using the port since it's a) cheaper to piece their own machine together and leave the specs up to themselves and b) Windows will probably run slower.

    Yeah, there might be someone out there bragging about running Windows on an Intel Mac but he's probably the rare Window's equivalent to the guy with a penguin displayed on his microwave's LCD.
    • The only reason Windows won't run right now is because of the Intel Mac's usage of EFI over BIOS. Windows only supports EFI on Itanium, and we all know how popular that platform was.

      Anyway, the code is already there for EFI support in Windows - but only on the 64-bit Itanium platform. Microsoft has said that they will support EFI on Vista, so while you're right for about the next eight months or so about needing an emulation layer for BIOS, by the end of the year Windows will run natively.

        I haven't seen Apple's EFI implementation, but the EFI spec says it takes over the duties of a bootloader and can be used by itself to boot from different partitions. There are defined codes for all the Windows filesystems. I don't even see why you'd need GRUB at all.

      Let's face it, one reason people "buy" Windows is that the cost is hidden in the cost of the machine. This is also generally true of OS X (the cost is hidden) but the hardware is "cooler." Your average consumer who buys an Apple does so because of design or ease of use.

      In order to run Windows on Mac hardware, it would first be necessary to buy Mac hardware, which isn't cheap. (The value proposition of Macs is a separate issue). Then, you have to look at the OSX interface goodness and decide that you want Windows instead. After that, you have to do whatever porting is necessary and install Windows. All this to get cool hardware running a not-so-cool OS. I mean, Apple is the BMW of computers and Wintel is the Ford. Are you really going to buy a 3 series and stick an Escort engine in it?

      If and when Windows supports booting without a BIOS, I can see some folks having dual-boot Apple hardware. Especially folks who want Apple's nicely designed hardware but still want to run Windows games.

      But an out-and-out port seems unlikely.

      Looking at the problem from your angle, you're right. As a Mac user who needs to occasionally run Windows, I think you miss the point. It's not about cost as much as convenience and quality of experience. Many Mac users are in the same boat. We need to run some Windows program but would love the opportunity to get in and out of Windows as quickly as possible without extra computers or the molasses speed of emulation.

      When I get my new Macbook, I will still need to run Windows and certainly won't want to drag around a second notebook. I run VirtualPC now and am very much looking forward to being able to run Windows natively. Remember that over half of all Mac sold are laptops.

      You are also forgetting that many Mac owners don't want to run some pieced together kludge box any more than most people who are proud of their cars want to drive some pieced together junk pile, faster, cheaper or not. Performance and cost aren't the issues as much as the elegance of the solution.

    Apple hasn't done anything to preclude Windows, or any other OS, from being installed on the Intel-based Macs. That is a perfectly accurate statement. Apple Vice President Phil Schiller's two direct quotes on the subject, the most recent which was made on January 10, 2006, can be seen here [appleintelfaq.com]. Intel has also specifically said [appleintelfaq.com] that Apple will not be using proprietary chipsets and/or processors, and they'll just represent standard Intel offerings.

    Windows XP would directly boot and install on the Developer Transition Kit platform because it was just a standard Intel motherboard and processor, and also used a standard Intel BIOS [appleintelfaq.com].

    However, the shipping Intel-based Macs use EFI [intel.com] (Wikipedia article [wikipedia.org]), Intel's "next generation of BIOS". (more info [apple.com])

    Windows XP 32-bit does not currently support EFI for booting. Windows XP 64-bit does, but Intel Core Duo is not a 64-bit chip. Now, there are a bunch of other variables, such as whether or not Apple's current EFI implementation offers BIOS backward-compatibility, and so on, but it's clear that regardless, EFI is the future, and it's only a matter of time before the PC world at large transitions to EFI. Further, Windows Vista does support EFI. See here [google.com] for Microsoft's presentations on EFI, particularly the first two links.

    That said, dual booting is intensely annoying anyway, and the really interesting thing will be able to just run Windows (or some other x86 OS) and Mac OS X side-by-side.

    What we will *definitely* see are "Virtual PC"-like programs that let you run Windows alongside OS X (in a Window, or taking over the screen, etc., with a hotkey to flip back and forth, for example).

    It's important to note this will NOT be emulation: Windows (or other x86 OS) will run at essentially the native speed of the underlying hardware (with certain exceptions). There could even be direct access to video, with support for things like DirectX.

    vmware already has a version for Mac OS X in development, and Microsoft has already announced [eweek.com] they will be developing a version of Virtual PC for Intel-based Macs that one can only presume will be a virtual machine. Then there are things like QEMU, Xen, etc. The Darwin/Mac OS X version of WINE, DarWINE, has even been working under betas of Mac OS X for Intel. Now that Intel Macs are shipping, it will only be a matter of weeks/months before we have several options for running Windows itself, and/or Windows applications at essentially the native speed of the underlying hardware.

    And since Intel Core Duo [intel.com] also supports [wikipedia.org] Intel's VT hardware virtualization, the possibilities of future virtual machine technology are even more interesting. But the bottom line is that Apple is again leading the way with the adoption of technologies like EFI and ExpressCard [expresscard.org]. Naturally, it will take a little while for Windows to catch up. ;-)

    So which way to the first full dual booting machine? Some hacking to get around Windows EFI issues to get a dual booting mac going, or full shipping OSX hacked to real functionality on Generic PC's?

    Yeah I know OSX on generics has been done, but to keep the race fair lets make it official shipping OSX which is suppossed to be harder to hack.

    Personally I am interested in a new dual booting machine and would prefer the windows on Mac option as that probably needs less hacking to get it to work and will likely be more stable.

    Heh.

    But really, once Windows XP and Linux are booting on a Mac, I doubt many developers in the world will ever buy anything else. This might be the unseen shift everyone has been waiting for - now you can get a decently performing dual processor machine that runs nearly every OS for less than $1300. With a 500GB internal drive on an iMac, Linux/Windows/Tiger can live comfortably.

    Remember, once Mac applications are running natively on Intel, it won't be too hard to port them to windows, and vice versa. If Apple ever releases an XCode that will wrap Windows widgets around Objective-C... kinda close to game over.

    For its part, Microsoft encouraged Apple to build hardware compatible with Windows.

    That's really really funny. Ever heard someone say "you only get what you deserve"? Boys and girls of M$, pack your stuff...Steve Jobs got a brand new bag.

    I suspect that unless someone comes up with a replacement HAL that can deal with EFI, we will likely have to wait for Vista for an EFI compatible Windows.

    A friend of mine inside Fruitco says that if you hold down "option" during boot, you'll be able to select among the available bootable partitions, so it does look like booting EFI compatible OSes should be easy.

    It's clear that Linux or one of the BSDs or some other *nix will be first to boot on one of these machines before Windows. Of course, my question at that point would be, what's the point? [apple.com]

    XP has to have the runtime services provided by the BIOS to boot (INT 19h, INT 13h, data tables, etc.). The XP bootloader also starts in "real mode" (think 8086, 1MB memory limit, 16-bit instructions, etc.).

    EFI doesn't provide any of the BIOS interfaces natively. It also boots up in 32-bit protected mode, which the XP loader can't use.

    Any EFI system that can also boot OS from current PCs (XP/DOS/Linux) carries an extra component called the "compatability support module" (CSM). This overlays the BIOS interface onto some EFI implementations, but this is only licensed from a few BIOS vendors.

    Apple doesn't need the CSM code to boot OSX, so it's not on their platforms.
    No CSM ... no Windows XP.

    Vista might work, because it has a native EFI install mode ... but Vista EFI might only come in the 64-bit flavor. Apple's current platform is 32-bit only. The current EFI standard (EFI 1.10) doesn't support x64. The upcoming standard (UEFI 2.0) does support x64, but won't boot an x64 OS unless the firmware is 64-bit (runtime calls to the firmware have to match the native platform firmware, and x64 can't make callbacks in 32-bit protected mode ... so 32-bit firmware only boots a 32-bit OS, and 64-bit firmware only boots a 64-bit OS)

    So Vista would only be viable if (a) Apple makes a 64-bit MacIntelTosh, or (b) Microsoft makes a 32-bit EFI/UEFI version of Vista.

    Yes, you need an EFI-capable operating system.

    However, keep in mind that these systems are Vanderpool enabled. The intel core duo processor has VT (vanderpool features).

    At a minimum, you can have EFI Linux and EFI OS X running side by side.
    Then you can run XP or Vista or DOS or Windows for Workgroups 3.11 in Qemu or VMware or whatever on Linux, or on Virtual PC on OS X.
