New modified BOOT-132 allows you to boot retail DVDs

1,305 posts in this topic

Recommended Posts

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.

 

Infos about hardware:

 

[OFF]: Vanilla = Original Mac OS X DVD or Mac OS X Installation with running original mach_kernel.

 

AMD systemz isn't supported.

To use Mac OS X Vanilla DVD needs a Intel "Mac" closer systemz, like a Intel Core processos and Intel Chipset. This is only combination supported by "Vanilla Installz", other processors and chipsets isn't supported by "Mac OS X Vanilla systemz"

 

You *can* boot and install retail on any SSE2 or better Intel pre-Core architecture systems, but you wont be using the vanilla kernel. See below for link

 

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.

Tested personally... it works perfectly!!! Installing and updates from Apple's auto updater... A landmark in OSX86 History!!!

 

P.s.: tested on a GA-945GCMX-S2 with E2200 processor, on an Acer Aspire 5920G. Perfect!

 

NOTICE: Once the system is installed you can put up chameleon 1.0.11 and put dsmos.kext manually in the extensions of the hdd to make it boot without the "magic" CD

So as for now, this will let you boot a retail disc, and use kexts that you put in a folder in a dmg file. But you would still need to installed chameleon or pc-efi after to get the hard drive to boot. Is that correct?

 

And if this is the case, is this really any different than having to install kexts by hand after the fact?

 

I can see this being very useful if it installed chameleon or pc-efi and brought up the bootloader. Otherwise wouldn't you need efi?

There's nothing to stop you putting chameleon on there & installing it in the same pass..

Awe man, this is awesome! I just wish there was some way to use it on AMD. Oh, well...guess it's time for an upgrade!

Anyone tried this with Snow Leopard.

 

For Snow not done. Need modified bootloader.

This is neat, just tried it. It booted to the background, booted Leopard DVD and spun the beachball for a long time (10 minutes?) until I reset it. How can I diagnose the problem, maybe I can do verbose on booting the DVD. This I tried on a Biostar 945G 775SE with C2D. It is currently running 100% on 10.5.4.

 

I also tried it on my iMac Core Duo and it booted to the installer no problem. In System Profiler it does not know it's an iMac but just "Mac", and the resolution is not full 1680x1050, some VESA default I guess.

Don't just burn the ISO, you NEED FIRST to put DSMOS.KEXT into initrd.img, otherwise, the spinning beach ball of death is what you get! That's why it worked in the iMac and not in your hack!

My process (DVD still freezes however)

• Mount the ISO

• Copy the initrd.img to the local disk (Desktop or whatever)

• Mount the initrd.img with the finder

• Edit the Extensions folder by adding dsmos.kext

• Use the windows program MagicISO within crossover or darwine to edit the iso, removing the old initrd.img and replacing it with the modified one

• Save :D

• Burn the newly modified .iso

 

Again, this works somewhat for me (I can see the kexts being read before the disk boots) but I get a spinny beachball as soon as the grey screen for the installer comes up. If someone has a better method, or can tell me what I'm missing besides dsmos.kext, I'd appreciate it. Good luck all.

 

I should also mention I'm running a Gigabyte GA-P35-DS4 board with an E6700 C2D and a nvidia 7600 GT.

A driver to handle CD/DVD-R boot is needed to allow booting from the CD/DVD drive using the bootloader in an USB Stick. Right now, only the swapdisk is possible, because BIOS can directly boot it and no driver is needed, but who knows in the (very near?) future... :D

Guys, no hard, simple method. I mark in red "what to do"...but, post here too:

 

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.

 

Only this, I resume (again):

 

#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!

I did exactly that a couple of times (first with the default iso, then with inserted dsmos.kext) in both cases the further I got was the stars background and a nice beachball.

 

I know is not an hardware related problem, since my computer is able to boot an installation made with the retail dvd using another leopard install (I just have to delete AppleCPUEnergy, and add dsmos and pcefi).

I got dsmos.kext properly loaded, I could see how it was loaded before the kext on the dvd were. But again...beachball.

 

That's how I did (but didn't pass the beachball)

 

1.- Extracted initrd.img with Winiso

2.- Inserted dsmos.kext with Transmac

3.- Deleted original initrd.img and insert new initrd.img with Winiso

4.- Burn.

Asus P5KR, P35 + ICH9R

Intel E6600

Sapphire x1950 Pro

2x 1gb Kingston DDR2 800

3x SATA2 Seagate HDD AHCI configured.

SATA Sony DVD Recorder

PCI Pinnacle 300i DVB-T Tuner

PCI SoundBlaster Audigy2

PCI Realtek 8139 NIC

 

The DVD is a DVD9 backup from a retail 10.5.2 install disc (h-mol1052.dmg)

 

As I said, my system is pretty compatible (just the onboard Attasic L1 NIC doesn't works). The only modifications to a retail installation (from a working system) I need in order to get Leopard booting is removing AppleIntelCPUPowermanagement.kext, adding dsmos.kext, and installing PCEfi...with that the system boots properly. Then I just need to install the standart video&audio mods.

 

Btw, may this method help for those with ACPI DSDT tables problems?

Try install using Chameleon.

 

Install first system, reboot, boot with CDBoot, install Chameleon and kexts, reboot without CDBoot.

 

Goodluck,

 

Edit: AppleEnergy.kext? :)

Errr...woulnd't that completly miss the point of all this stuff? Booting and installing retail dvd´s?

 

I already can install with a retail dvd from an already installed Leopard system. But that makes you install a hacked dvd before you are able to install the retail one.

 

Isn't CDBOOT mean to save you from that?

 

My plan was:

 

1.- Use cdboot to install directly from the retail dvd

2.- Use Transmac or something else to delete AppleIntelCPUPowermanagement.kext, and install dsmos.kext

3.- Install PCEfi, or Chameleon

 

But sadly I couldn't pass the beach ball mouse pointer.

I meant AppleIntelCPUPowermanagement.kext

I believe this bug is related with your video card. I'm testing in Intel GMA950 with Leopard and Snow and worked fine.

 

This is a first version, I (and team) can't guaranteed that I would work with all hardwares existing.

 

We see bugs in this version to try fix in nexts.
