[Guide] Boot from EFI partition, zero modification installs on Intel SSE2 or better...

OldPoem · September 22, 2008

Working with 10.5.0 Retail Disc. But after install 10.5.5 Combo Update it hangs when boot.

Still looking for Solution. Only 4 kexts in EFI Booter - dsmos , ps2nub , PMDisabler , SMBIOSEnabler

looking good so far just need some more polished bootloader.

kennyp · September 22, 2008

OK the Asus P5Q is working, this method works great!

The list of kext placed in the Extensions folder are:

ACPIPS2Nub.kext

AppleAC97Audio.kext

AppleACPIPlatform.kext

AppleAHCIPort.kext

AppleAPIC.kext

AppleAzaliaAudio.kext

AppleGenericPCATA.kext

AppleHDA.kext

AppleIntelIntegratedFramebuffer.kext

AppleNForceATA.kext

ApplePS2Controller.kext

AppleSMBIOS.kext

AppleVIAATA.kext

dsmos.kext

HDAEnabler.kext

IntelCPUPMDisabler.kext

IONetworkingFamily.kext

NVkush.kext

SMBIOSEnabler.kext

I have placed them in a handy dandy zip, so you can just drag them over to your Extensions folder. P5Q 2.zip

All the kext were not needed for my board, but should be good to get most systems to boot. (Asus, Gigabyte, MSI w/P35 or P45 chipset.

Munky, I did not need system.kext on this install.

I still have issues with 1) Sound; ACL1200 -not apple supported 2) Video ATI Radeion HD3650 not apple supported 3)On board ethernet - installed Netgear GA311.

I have had to (so far) install sound & video after install....not vanilla anymore....so I'll keep working on it before I change over my main drive.

Thank you Kennyp for your advice, I'll try it tonight.

Crawley · September 22, 2008

Finally works on asus p5b...

I tried last night without success, but it turns out that, somehow, my dfe usb pendrive was halting boot all the time. today I just removed it from USB port and to my surprise I got successfull boot

munky · September 22, 2008

LOL nice one Crawley :-)

shatterhenner · September 22, 2008

hi...

reporting success here with 10.5.4 retail disc on p4/2.8/i865 hehe ;-)

set up 10.5.4 with bladerunners iso

doin the efi partition magic....thanx munky and the devs, amazing work

reboot with prepared efi partition voodoob1

update to 10.5.5

and reboot with voodoo95a7 for the first time

reboot and fine ;-)

question:

can we quick edit (installl/deinstall) kext on efi partition??

thanx

Neonkoala · September 22, 2008

Anyone know how to load this from the Vista bootloader? I would like to keep Vista in the mbr for various reasons. I tried extracting the boot0 MBR and loading it from the Vista bootloader but it just cycles back to the MBR. Will chain0 be able to see the EFI partition for booting?

Crawley · September 22, 2008

got it working' perfect!

tnx for the awesome work!

is there a way to boot automatically selected partition? (My Os X is installed on the third partition and I want to boot it as default system) i've read something about UUID but I'm not quite sure that I understand it...

roidm · September 22, 2008

question:
can we quick edit (installl/deinstall) kext on efi partition??

thanx

open a terminal and type

sudo -s

mkdir /Volumes/EFI

mount_hfs /dev/diskXs1 /Volumes/EFI (X=EFI disk)

killall Finder

you will see the EFI partition mounted in your desktop

to unmount

sudo umount -f /Volumes/EFI

rm -rf /Volumes/EFI

munky · September 22, 2008

oldpoem : some people have reported u need to boot with -f the first time after updating to 10.5.5 - give it a shot.

I'm glad for your success, but I gotta tell you - that's down right depressing

I mean, all this success using my iso and I can't even get my EFI setup to begin to boot. It's just not fair

Still, I'm truly glad others are doing well. I will figure it out eventually.

munky · September 22, 2008

Hi blade,

What exactly is the problem you're facing?

You're pre-Core CPU yes? I'm pretty sure that means u need System.kext on efi partition.

What is on ur boot132 ramdisk, and what's on ur efi part?

How far does booting get?

One thing to try: remove any other disks which have bootloaders, esp other chameleon installs.

Try to boot ur system with only ur Leo drive. U did repartition as gpt etc?

DB1 · September 22, 2008

Wicked work guy's - munky, turbo, dense, dfe, zef and everyone else involved you guy's have taken osx86 to another level. Much appreciated.

Success to report on Asus P5K - VM, Vanilla 9.5 / 10.5.5 everything working. EDIT: except sound: fixed with ALC883 installer from Kalyway install disc;

Here's the kexts that worked for me (some may not be needed but I dont want to mess about when I know this combo worked):

AsusP5K_VM_kexts1.zip

AsusP5K_VM_Kexts2.zip

ALC883.zip

shatterhenner · September 22, 2008

open a terminal and type

sudo -s

mkdir /Volumes/EFI

mount_hfs /dev/diskXsY /Volumes/EFI (X=EFI disk Y=EFI partition)

killall Finder

thanx roisoft for the quick reply...ill try tomorrow

i ran it that trouble already on my homedesk(specs below)

had to switch sata cables to get into bootable efi partition...

my old bootloader is still present at startup

time to sleep thanx again guys

The problem appears that the loader can't locate the kernel. At boot time I see a quick flash of test and then what looks like an F8 partition list. I select the partition and enter

bt(0,0)/mach_kernel.modbin

The kernel flags, -v -f and boot-uuid=, are coded in the Boot.plist on that partition

What I see after that is another quick flash of text and the same list of partitions. I have also tried entering the kernel flags and rd=disk0s3 on the boot prompt - the result is always the same.

EDIT: I just noticed that if I don't enter anything at the boot prompt - as if I wanted to run the vanilla kernel - I see the full range of kext loading messages fly past before the screen blanks and then the system reboots.

Also, I powered down the system and unplugged all the external drives. the boot results were the same as previously reported

/Edit

After your comment about this loader not processing EFI strings I removed them from my Boot.plist and inserted Natit.kext in my boot 132 ramdisk. once I got that running correctly I used it to build the EFI partition. The Extensions folders on both the EFI partition and the boot132 CD have the same content. i.e.,

bash-3.2# ls -l /Volumes/EFI/System/Booter/Extensions

I have re-formatted and re-constructed the EFI partition at least three times - including the fdisk and dd command portion - always with the same result.

I am going to include information about my internal hard drive in case you can see something there.

/dev/disk0
  #:					   TYPE NAME					SIZE	   IDENTIFIER
  0:	  GUID_partition_scheme						*298.1 Gi   disk0
  1:						EFI						 200.0 Mi   disk0s1
  2:						EFI						 10.0 Gi	disk0s2
  3:				  Apple_HFS Production			  110.0 Gi   disk0s3
  4:				  Linux LVM						 50.0 Gi	disk0s4
  5:				  Apple_HFS Maintenance			 70.0 Gi	disk0s5
  6:				  Apple_HFS Data					57.3 Gi	disk0s6

Partition 2, which started life as FAT32, is formatted as type 83 - native linux. Partition 2 showed as fat32 until it was reformatted as native linux. With pc-efi-v8 installed as the boot loader the partition menu shows 2 as a foreign os and partitions 2,3 and 5 are bootable. Partitions 3 & 5 are OS X systems.

All my drives are partitioned as GUID. I don't run Winxx on this system - except for the one under Parallels. there are two firewire external drives. One is storage for TimeMachine and the other is my general work area.

I know I must be doing something wrong -I just can't locate what it is.

kennyp · September 23, 2008

Anybody know how we might keep an offending kext from loading that is in the vanilla install?

The problem I am having (same with iATKOS) I can install Retail fine, boots back up fine. Then the 10.5.5 update replaces my ATI video driver. The screen goes to funky shapes, and colors upon reboot.

The only way I could get it to work is delete all ATI related kext, and install a modded driver pkg, same thing happened with iATKOS.

I can get it to work, but it blows the vanilla concept.

Try adding it to the disabler kext. In the Disabler info.plist there are entries like the following for each kext to be disabled

			   <key>IntelCPUPMDisabler</key>
			<dict>
					<key>CFBundleIdentifier</key>
					<string>net.osrom.kext.Disabler</string>
					<key>IOClass</key>
					<string>Disabler</string>
					<key>IOMatchCategory</key>
					<string>AppleIntelCPUPowerManagement</string>
					<key>IOProbeScore</key>
					<integer>1000</integer>
					<key>IOProviderClass</key>
					<string>IOResources</string>
					<key>IOResourceMatch</key>
					<string>IOKit</string>
			</dict>

Make such an entry for your problem kext

Hey, munky.

Congrats for your great job and your thrilling last findings!

I know I might look annoying, but I have been trying everything and I am still not able to make a boot CD for the phase 0 of my installation. I have burned 950 times the same CD-RW with different kexts. So you are my only hope, at the moment!

I have an old P4 630 3,00GHz (capable of x64, though), on a P5GL-MX Asus motherboard with Intel 915GL and Intel ICH6 Chipset and a NVIDIA 7600GT 256Mb graphic card. Of course I disabled GMA900 from my BIOS. As a network card, I have a realtek8139. I have GUID formatted Sata HD. I run iDeneb v1.1 and it goes perfect with 10.5.4.

In my last CD, I have put the following kexts:

ACPIPS2Nub

AppleAHCIPort

AppleAPIC

AppleGenericPCATA

AppleNForceATA

ApplePS2Controller

AppleVIAATA

dsmos

IntelCPUPMDisabler

SMBIOSEnabler

System

How come I keep getting errors and the usual "waiting for root device"????

Should I try to install Chameleon DFE for Hard Disk or something similar?

Can you help me?

Thank you in advance.

munky · September 23, 2008

b612: please post the exact string you enter at the boot prompt. Remember for pre-Core CPUs u need to specify a patched kernel on ur ramdisk and a boot uuid or rd to boot. If you have not done this, please read my boot132 on pre-Core thread which is the first link in my sig.

Bladerunner: sounds to me like you are booting not from the EFI partition but from an existing chameleon on some other partition. Could u possibly disconnect all drives except one test one for Leo, and make sure you completely destroy all partitions on ur test drive before u start.

The reason I suspect you are not booting from efi is that bt(0,0) refers to the boot device, so provided you have the correct kernel name (and it's in the root of efi) it should definitely find it, unless efi is NOT the boot device, which is what I think is going on.

munky, thank you for your reply.

The string I enter is:

rd(0,1)/mach_kernel.modbin -legacy -v rd=disk3s0

Then I see the boot of the retail DVD in verbose mode, but before starting the real installation, while loading the kexts, I get the "still waiting for root device" message.

Of course I have read everything you have written and many more things written by others, otherwise I wouldn't have disturbed you.

Do you have any ideas?

jokinawa · September 23, 2008

B612 if you have not tried see if your motherboard supports AHCI and enable/disable it.

OK, I'll try to disable and let you know. Thanks!

munky · September 23, 2008

afaik two things can cause this:

1) missing chipset/ATA drivers. im not too sure about these. what chipset does your mobo have? what southbridge?

2) specifying the wrong rd=. try booting the retail DVD again, and open Disk Utility. click on the partition to select your install and click the blue I information button. find the 'Universal Unique Identifier' string and write this down on a piece of paper.

now try booting with boot-uuid= instead of rd=diskXsY and post ur findings.

I guess my chipset is ICH6?

2) if my "rd=" was wrong, could I be able to start the DVD in verbose mode etc? Wouldn't it stop before the process to begin? (before inserting "rd=disk3s0", I checked the info button in Disk Utility)

Do you think I could try using a different kernel, like TOH? It would be a shame, though, because I am actually using 9.4 modbin on my iDeneb installation.

Thank you!

PS: @jokinawa: disabling AHCI didn't work. Thank you anyway
