OpenOSX Provides Virtual PC Alternative

lucas.clemente writes "OpenOSX has just announced a cheap alternative to Microsoft's Virtual PC for Mac OS X, OpenOSX WinTel. What's more, the OpenOSX version will be compatible with Apple's new G5 architecture, whereas Virtual PC users will have to wait until the next major upgrade for G5 compatibility." It's a frontend to bochs, which we've discussed before as a possible Virtual PC replacement, and the biggest obstacle seemed to be getting it up and running. Perhaps this product will fill that hole. Prices start at $25 for download, but it is covered under the GPL.

    Bochs is so much slower than Virtual PC that I don't consider it an alternative at all.

    Getting Windows 95 to run acceptably on my last comouter was impossible in Bochs, and oh so easy in VPC.

    Just wait for a VPC update. I'm sure you won't have to wait for 7.0.

    Also, I refuse to use software from OpenOSX. All they do is recompile popular software, then put it on CD for you for silly amounts of money.

    I.E. - Want GIMP?

    Step 1) Download and install fink - http://fink.sourceforge.net

    Step 2) % sudo apt-get install gimp

    Pay OpenOS X a whole bunch of money.

      I suggest that you not hold your breath on that: Microsoft Knowledge Base Article - 827904

      excerpt:

      Virtual PC for Mac Version 6.1 and earlier use a feature that is present in the PowerPC G3 and the PowerPC G4 named "pseudo little-endian mode". Virtual PC for Mac uses pseudo little-endian mode for increased performance when it emulates a Pentium processor. Virtual PC for Mac 6.1 must use pseudo little-endian mode to function.

      The new Power Mac G5 processor does not support pseudo little-endian mode. Therefore, the current versions of the Virtual PC for Mac program do not run on the Power Mac G5.


      This is a non-trivial problem.

      Bochs is so much slower than Virtual PC that I don't consider it an alternative at all.

      I don't have any inside information, however, I am suspecting that the next version of Virtual PC will be much slower on a G5 than Virtual PC (current) on a G3/G4 class machine.

      The current version gets a big speed boost, because the G3/G4 processor can run in little endian mode. The new version for the G5 is going to have to spin every opcode from little-endian mode to big-endian mode, run the command, then (possibly) convert back to little-endian mode.

      I suspect that versions of Virtual PC that ran on 604 based Macs will run fine on a G5...just slower than the current Virtual PC release on slower hardware!

      I suspect that versions of Virtual PC that ran on 604 based Macs will run fine on a G5...

      Except for the fact that those versions of VPC were pre-OSX, and it's dubious that they will run under Classic.

      I'm awaiting the inevitable benchmarks that compare various emulated Windows performance under G5 Bochs to VPC 6.x on a decently fast G4.

      I'd rather run Bochs for free (or at worse, very cheaply) that pay significantly more to Microsoft for crippled future releases of VPC to ensure that performance sucks (even after the architectural differences are taken into account).

      If Microsoft wanted to, they could easily buy back a lot of the performance lost due to manipulating addresses and integers by producing versions of DirectX and other drivers that talk directly to the underlying hardware. Look at how poorly existing VPC manages the video -- emulating an older graphics chip not present in any Mac.

      Even if Bochs only ran in full screen mode (to avoid sharing the display with OS X), the performance gains from native instead of emulated video are likely to be quite significant -- maybe not enough to totally overcome the performance hit due to the loss of the pseudo-little endian mode, but I'll bet the G5 can make up the difference.

    4. Re:Bochs by Textbook+Error · · Score: 4, Informative

      It is, because the G5 DOES support pseudo little-endian mode. It must be a stupid fuck-up on MS's side (as if that'd suprise anyone).

      VirtualPC does not use the PowerPC's ability to boot in big or little endian - it uses the lwbrx/stwbrx instructions, which will automatically endian-swap during a load or store. This allows them to keep data in memory in little endian form, have it swapped automatically when it's brought into a register for processing, and have it swapped back when it's written out to memory.

      This is the feature which isn't present on the G5, and was responsible for the big speedup in the latest rev of VPC - and the reason it now requires a G3 or G4 (since the previous PPC chips didn't support these instructions).

      Since the G5 doesn't support this feature either, they'll need to go back and resurrect some of their previous code - they will doubtless take a performance hit for having to do the swapping themselves, but the massive bandwidth in the new systems will probably help cancel some of that out.

    Ok, so this new alternative may not be as fast as Virtual PC. But you know what really impresses me? Look at how quickly an alternative to this Virtual PC problem was produced. Five years ago, it would have been "eh, it's just Mac. Screw 'em." But the G5 just came out and there's already an alternative to a problem. Perhaps it'll keep Microsoft on their toes. Perhaps other developers will go "damn, we best be writin' some stuff for them too." It's refreshing to see developers rushing to fill the void so quickly.

      Uh, not really. OpenOSX is selling WinTel since December 2001. So it's more like a "look how quickly someone got the idea to use the VPC/G5 incompatibility to get some free PR". For a public relations stunt, it was not really quick.

    There are a number of issues that are important about Open OSX and bochs.

    1 As said before, bochs is extremely slow. Their own page does not even recommend that you install Win2k or XP.

    2 This project is not new. It has been around for I don't know how long, at least a few months. The only new thing is support for the G5.

    3 It is suspected that this organization is ripping off compiled binaries from Fink without giving credit. Read about it in the Fink FAQ.

    It would be much more useful for someone to create an OS X port of qemu [http://fabrice.bellard.free.fr/qemu/] and wine [winehq.com] and post it somewhere. Both of these programs have very good things said about them, as far as performance and stability, but I don't know how well they work on OS X.

  7. want the story on OpenOSX? ask Robert Atlee! by Anonymous Coward · · Score: 5, Interesting

    Robert Atlee was one of the founders of this company, and provided a substantial part of the initial equipment and funding. He is listed on the contact page rather unprofessionally as "terminated." I spoke with him on the phone about three months after he footed the bill for the double-wide booth that Jeshua Lacock ran at MacWorld. He was rather upset at the time that Jeshua had basically skipped town with a bunch of his computer equipment and had locked him out of the web server etc. I'm sure that every story has two sides, but at this point in time, not only Mr. Atlee, and Christoph Pfisterer, but also myself have received poor treatment at the hands of Jeshua Lacock, the sole proprietor of OpenOSX.

    Slashdot doesn't probably have the budget that professional news sources do, so we can't expect all of the stories to be double or triple cross-checked. My guess is that if you start asking around (tax records? employees? better business bureau?), you'll find that few others have genuinely benefitted at the hands of this opportunist. The MacGIMP project helped to fund GIMPCon 2003. Has OpenOSX EVER given back to the community that built the software it sells?

    One of the first rules of polite public behaviour is to give credit where it is due. Jeshua has attacked my reputation and left a rude web page up with my name on it (after numerous requests to have it taken down) and upset a very good open source developer (Chris Pfisterer) and has managed to con his business partner out of the equipment it took to get everything he had started. Make up your own mind, but I refuse to do business with someone who has managed to offend this many reasonable people without having made any visible efforts whatsoever to set things right.

  8. For desktop users, just add a PC by jeffreym · · Score: 4, Informative

    I've been using Windows emulators on Macs since the "beginning" and have 4 licenses for VPC currently, but we use them on laptops, where it would be inconvenient to bring along a PC laptop AND a Mac laptop just to have access to more than one platform. For desktop use, one can add a PC for not much more than the price of VPC + OS and, if space is a problem, as it is for me, build an inexpensive Athlon PC with a Shuttle case and put in a KVM switch to keep to a single keyboard and monitor.

    We have 3 shuttles with 2400+ processors, 256MB ram, 80GB drives, running Windows 2000 Pro. We already had flat panel monitors which the iBook users mirror when sitting at a desk, so it was simple to place a KVM between their external keyboard/mouse and monitor. The cost of the box was less than $400 each and that included an OEM Radeon 9000 Pro in each of them, which is not really necessary for standard 2D work as they come with decent graphics built in for modest 2D work.

    I just don't see the gains for running VPC on a desktop Mac considering the low price of PC hardware; but for a laptop, it's really handy and since there's not much chance of a G5 laptop anytime soon, we can hope there will be a workable solution when and if the G5 architecture comes to Powerbooks.

    Look, I loathe and distrust Microsoft as much as the next guy, but--what incentive do they have to cripple Virtual PC?

    Microsoft profits from the sale of Windows for Virtual PC in the same way it profits from the sale of Wndows for actual x86 hardware.

    Microsoft may very well sell other software products that run under Virtual PC at the same rates they sell those products for actual x86 hardware.

    Apple is only the enemy of Microsoft because Apple hardware a) doesn't run Windows and b) exemplifies an alternative to Windows hegemony. But,

    It seems to me that if some application is capable of running Windows and Windows applications aptly on the Macintosh platform, this turn of events is only in Microsoft's interest.

    I mean, they have no real hope of "crushing" the Macintosh platform -- there are too many addicts, Apple is far too liquid, and people just plain hate Microsoft. Virtual PC provides them a way to continue to profit from Apple.
