Modified BOOT-132 enables vanilla install from retail Leopard

Recommended Posts

Sorry, I know that I'm a bit late to post this.

An explanation of how this works

Original thread by f41qu3 - report your discoveries and successes here.

Questions & problems go here

Developed a configuration that works? post it here for the next guy

 

David Eliott has just released a new version of his modified boot-132 bootloader.

One of the new things it can do is to load kexts from an .img file which contains kexts (or even an mkext) and boot Leo.

That means you can have two mkexts, one folder with kexts on the .img file and the folder with kexts from your installed system

or even two folders with mkexts.

How does it work?

 

Basically, you create a flat dmg with the kexts in a folder and the bootloader will load them for you. This means quite a lot;

you can boot from a retail Leo DVD and install it, you can update straight from apple, you can reinstall and not have to add

the same kexts to your install every time. The bootloader behaves like the linux kernel: you can use an mboot (a patched syslinux

was used) compatible bootloader which tells to boot-dfe about the .img file (the ramdisk or initrd, as it's known by the linux users)

and boot-dfe is going to use the kexts (or mkext) from it.

What does it do?

 

This new boot-dfe has been tested with the retail Leopard DVD and it can boot, install and run Leopard without having to build

a modified DVD.

 

This is how it's done: you burn an ISO (which has the bootloader on it) to a CD/DVD, after it gets to the boot

prompt, you press ESC or ENTER and it prompts for a new BOOT DEVICE, you swap the BOOT CD/DVD with the LEO Retail DVD, you press

enter and it shows you the name of the bootable partition from the DVD, you press enter and Leo starts to load.

 

Quick resume about "oh, what to do now?"

 

#1 - Burn .iso on a CD;

#2 - Boot this CD;

#3 - When Darwin prompt appear, eject CD and put Mac OS X Leopard Retail DVD;

#4 - Press enter (or -v and enter...wherever...)

#5 - After install, boot using CD boot again and install .kext needed...and usual files.

#6 - Done!

 

For the time being, you cannot have this bootloader on an USB stick and have it boot the Retail Leopard DVD. The reason why this

happens is related to the way the BIOS handles DVDs and optical media: there's no BOOT DEVICE associated with an optical drive

which the BIOS has not booted from. Basically, this is like the disk swap trick known to the PlayStation gamers.

You can already put this on an USB stick/CD/DVD and boot a vanilla install (vanilla= no added kext, no replaced kext on the partition).

 

As usual, this only works for compatible machines(that means you still can't boot a vanilla system on AMD, they need specialised patches).

 

What are you going to do in the future?

 

David Eliott said he'd merge some of the things from Chameleon into boot-dfe. Those involved in the development of Chameleon will merge

the support for ramdisks into Chameleon and more effort will go into making the distribution 100% legal.

Work might(read: should, in the very close future) also go into making Chameleon boot the Retail DVDs when loading the bootloader from the HDD.

 

User guide and link to the ISO

 

This ISO needs to be modded (add dsmos to the Extensions folder) in order to be able to boot Leo.

 

Credits for this go to:

 

David Eliott: for modding boot to allow us to boot from Retail Leopard DVDs;

 

Kabyl: for modding boot to allow the usage of a separate folder on the disk and merging features from Chameleon to boot-dfe-146;

 

bumby: for compiling syslinux and figuring out how to build the ISO

Cheerz,

I find that the HMBT Auto-Patch method is the easiest to use. This is a huge milestone for the OSx86 project. After installing with this method 10.5.0-10.5.4 works perfectly :censored2:

For help or information, please post in the original thread by f41qu3.

Perhaps that's how EFI-X works! (That's only a guess)

Anyway that is a good news to every Intel users

 

Sorry for AMD guys (including me)

I don't really see how anyone who has installed (and is running) successfully before can benefit at all from this method, or others... the most they could give you is a clear method to update without hassle, but that's about it?

Taking any update with no worries seems like a pretty big 'it' to me :thumbsup_anim:

I think the really big deal is we no longer have to rely on hacked DVDs, instead we can download a small iso image, burn it, and boot it, then boot the real dvd, thats the point! not to mention if updates can be done like regular Macs this could be what the community has hoped for. imagine running a hackintosh that behaved and updated more like a macintosh? doesnt that appeal to you on any level? or do u prefer waiting in line for hte next big 4 gb torrent to hit the web to safely install an update and get new kexts with out have to search the wasteland that is the internet?

Can somebody make a guide of how to get this to install on intel laptops, a step by step would be cool, how to get the kexts and other files needed.

 

How would we go about adding drivers like Intel 950GMA?

 

Also would be great if the file could be added under windows, then put on a USB stick.

 

I hope somebody can help.

Er... It already does, doesn't it?

 

Maybe it does, I was away for the weekend. Says windows, anyone set up a method for os x. No windows here.

Sure.

 

These are the files you need for using it on a USB Disk. I haven't actually tried it myself, but it should work. If it doesn't, let me know.

I must agree with JaS here, no more downloading patched dvds to try on different systems, would be a huge advance for this project.

 

Things must be aligning themselves nicely for me.

 

First, Kabyl creates a corrected bios for my 4Core1600Twins-P35 ASRock motherboard, so that all cores can be used, and I don't have to boot with CPUS=1. Gotta try this soon, thanks Kabyl.

 

Second, This new boot-132 with separately stored and loaded kexts, to boot and install a retail dvd, very nice, thanks to the devs for this.

 

Third, The ability to put this on a flash drive to boot the system, or use chameleon to boot the native install, and move your kexts over to the hard drive, and not use the flash drive.

 

All in all, awesome, thanks to all

could somebody make an extensive guide on how it get this working, what are the most important kexts to use with the boot loader and how to add extra kexts.

 

What are the advantages of chameleon?
