i_am...me Posted November 27, 2007 Share Posted November 27, 2007 Since EFI v7.2 allows booting of GUID partitions, we cannot boot in to windows since we need an MBR, but boot camp must write a boot-loader of some sort to be able to boot in to windows. Here is the required ROMS <key>DARequiredROMVersions</key> <array> <string>IM41.0055.B08</string> <string>IM42.0071.B03</string> <string>IM51.0090.B03</string> <string>IM52.0090.B03</string> <string>IM61.0093.B01</string> <string>MP11.005C.B04</string> <string>MB11.0061.B03</string> <string>MBP11.0055.B08</string> <string>MBP12.0061.B03</string> <string>MM11.0055.B08</string> if we can crack boot camp and make "hack camp" so it wont check the ROM we can install windows again on our machines and boot in to them.

BOL_fan Posted November 27, 2007 Share Posted November 27, 2007 Frankly this would be an amazing development. The existing dual-boot methods for hackintoshes are pretty messy. Link to comment Share on other sites More sharing options...

i_am...me Posted November 28, 2007 Author Share Posted November 28, 2007 i though about it more, If we could create a program similar to acronis but for a mac. it could work, but we would need the boot files that get written to the boot camp drive. I just tried installing windows and it installed but it wouldnt boot at all after that so i re wrote the boot loader and now im back but i couldnt boot in to the vista partition so i deleted it, thank the lord for GUID,didnt even show up in the F8 boot menu.

i_am...me Posted November 29, 2007 Author Share Posted November 29, 2007 but the main UNIX file in to a hex editor and it does look like it has to write some sort of boot loader. is there anyway i could dump the text? Link to comment Share on other sites More sharing options...
tops Posted November 29, 2007 Share Posted November 29, 2007 This would be an interesting development... it seems possible now. I just used the 'reverse-Boot-Camp' phrase to explain to a co-worker how I got Leopard on my Dell. Imagine using Boot Camp on a reverse Boot Camp box. /mindblown.

Hyper X Posted November 29, 2007 Share Posted November 29, 2007 I was thinking about it and wouldn't rEFIt work with the EFI thing even if Boot Camp won't? Ideas or thoughts? Link to comment Share on other sites More sharing options...

Embio Posted November 29, 2007 Share Posted November 29, 2007 rEFIt might work, but doesnt boot camp just work as partitioning software and the real tricks like BIOS emulation and such are left to the Mac's firmware? Link to comment Share on other sites More sharing options...

Boot Camp is a Unix based app. i plugged the main file in to a hex editor and i saw that it writes something called "MDosStandard" or sumthing like that to the partition. And it wounldnt really be bio emulation it would be MBR emulation. check the hex dump above Link to comment Share on other sites More sharing options...
Superhai Posted November 29, 2007 Share Posted November 29, 2007 The bootcamp could be added into the booter, but somone have to rewrite it. And I am not sure if there is enough space in the efi booter to add that app. Link to comment Share on other sites More sharing options...
Envying Posted November 29, 2007 Share Posted November 29, 2007 If you are using a pc, you already have a chance to use Windows Genuinely. Why bother bootcamp, which is a bridge for mac to pc? I am just wondering if there is a way to run your windows from vm or parallels (their bootcamp option)... Link to comment Share on other sites More sharing options...

With EFI v.7.2 you can boot GUID partition tables, so no more NTFS or FAT32 Booting thats why we need boot camp. i have a feeling it write a boot loader to the boot camp partition since there is very small difference to the EFI im running and a real mac is running Link to comment Share on other sites More sharing options...
Azurael Posted November 29, 2007 Share Posted November 29, 2007 Because you're not running EFI! rEFIt won't work either. There's a big difference between a fancy version of the Darwin bootloader which is basically like Natit/Nvinject for booting, and actually having EFI firmware on your machine. Some of you don't seem to get what isn't a very subtle distinction! Link to comment Share on other sites More sharing options...

Hagar Posted November 30, 2007 Share Posted November 30, 2007 Gents, please don't get distracted by all the "is it or isn't it EFI" stuff.. fact is each release of pc-efi moves closer to functioning like true EFI, even though it certainly began as a clever hack to the darwin bootloader. Previously, the idea of running bootcamp on a hackintosh was pointless, due to all the differences between the hardware. With GUID partitions now coming into play, its functionality might be not only useful, but necessary in order to dual boot, and the strides being made with pc-efi functionality these days, it certainly deserves a second look.

Azurael Posted November 30, 2007 Share Posted November 30, 2007 No, because it's important for people to know. The number of times I've been asked stupid questions like 'will my computer's BIOS be erased' and 'will my computer go dong' beggars belief. It didn't just begin as a clever hack to the Darwin bootloader. It is still very much a clever hack to said bootloader. I'm not for a moment saying it's not a good thing. It's very important to OSX86 users as it makes life much easier for us (i.e. by bypassing the need for device injector kexts in the long term, allowing us to use vanilla updates from Software Update, etc.) I just want to make sure people understand what it actually is. No matter how good this modified Darwin bootloader gets, it will never be the same as running on a real EFI system. EFI modules are written to hand over values such as those needed to initialise the graphics card or HDA codec with no work on the user's behalf. With a hacked bootloader we still need to know what EFI would have reported to the OS and 'hard code' that into the bootloader. It will always have limitations when compared to a real Mac, especially when new hardware comes along on the Apple side, and we spend weeks working out how to get it to initialise correctly. If we had real EFI, we could just load the Apple modules for said hardware and forgo the reverse engineering. Plus, we will never be able to use a totally unmodifed Apple install disk. Anyway, back to the topic, why can't we just create hybrid MBR/GPT disks like Bootcamp does and then Windows should boot fine? We don't actually need Bootcamp to do that, do we?

curlyboy Posted November 30, 2007 Share Posted November 30, 2007 Well i have 1 drive as mbr which is my xp and the other as guid which is leopard and both work just great only prob i have now with guid is the fact that now in windows with macdrive it cant see the apple partitions other than that its great i use software updates straight from apple replace kernel with patched and bobs ya auntie good job all developers well done Link to comment Share on other sites More sharing options...
i_am...me Posted November 30, 2007 Author Share Posted November 30, 2007 I didnt want boot camp so when i hold the the option key while booting i would get the whole nice boot menu. I wanted it so i could be able to boot windows on my system, Now that i can re-size partitions as i wish when ever i want... But when i looked through the lines the only thing it checks is the IOTree for the boot rom version. Took the two lines out in the whole think and it still says to update my boot rom...
