boot with the dvd

open a terminal and type

diskutil list

diskutil unmount /dev/diskXsY

cd /volumes/"YourVolumeNameHere"/pc_efi_v80

umount -f /dev/diskXsY

./startupfiletool /dev/rdiskXsY ./boot_v8

dd if=./guid/boot1h of=/dev/rdiskXsY bs=512 count=1

diskutil unmount /dev/diskX

Here's another tutorial for EFI, which works for amd AND intel:

diskutil list

diskutil unmount diskXsY

cd /Volumes/bootloader/pc_efi_v80

./startupfiletool /dev/diskXsY ./boot_v8

dd if=./guid/boot1h of=/dev/diskXsY bs=512 count=1

dd if=./guid/boot0 of=/dev/diskX bs=400 count=1

there is a difference between Puttabong and the other guid: the one make rdisk the other one only disk
whats right now?

@Puttabong: u were right, there is a difference between Master and Slave on Sata! the board is looking for the right connectivity and switch between master/slave. i'm definitely on master now!

Puttabong;
Will EFI be installed automatically with Rev 2, or will it be an optional install at boot time? Also, does it really make a big difference to smoothness and stability? I personally feel that Leopard doesn't quite seem as 'solid' on my x86 hardware as it does with my other, lower powered PPC Macs.

Puttabong, any comments to my previous post, the difference between the 2 guides?

R0GUE, it's optional, you can choose EFI during the install process, but I'd recommend it.
I have experienced much better system performance with EFI. I know the reason why.

With the use of EFI, RC2 is able to use the apple stock kernel and kexts, and they work very well
together, as they are concerted. Selecting GUID + EFI and the proper chipset and graphic
settings, will give many systems a perfect out of the box install.

Also, read some other posts about EFI that I posted into the Discussions, I think I was talking about
improvements compared to PCBIOS. :)

Original by Netkas (about GUID)

Code:



 Fixed version

This arcticle will describe how to use guid partition table for OSX on your machine.

Making bootable guid:



1) get a harddrive and format it using Disk utility, use guid partition disk. Make as

much partitions as u want.

and OSX can be installed to any partition under 2TB on disk.

On guid disk u can have up to 128 partitions .

bootloader will boot first hfs+ type partition.

After u created partition, choose your drive in disk utility, press Info, and

remember value for disk identifier



e.g. if it disk2  - then X = 2 (X will be used later)



For all commands use root account

After it, go to terminal and type diskutil list

find there your guid drive

and find there device name for first hfs+ partition

e.g.



#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *55.9 Gi disk1

1: EFI 200.0 Mi disk1s1

2: Apple_HFS OSX 10.0 Gi disk1s2

# is your Y, so in this case, Y = 2, remember it



Now umount  your diskXsY partition (umount -f /dev/diskXsY ), did u forget your X or Y ? (look above if so).



cd to/folder/where/you/unpacked/pc_efi_v80/



./startupfiletool /dev/rdiskXsY ./boot_v8



dd if=./guid/boot1h of=/dev/rdiskXsY bs=512 count=1



now unmount all partitions on your guid drive (with disc utility e.g.)



imortant step(PRIVET)



dd if=./guid/boot0 of=/dev/diskX bs=400 count=1



your guid drive should be ready for booting now

reboot and try to boot from yout guid drive (with choosing bootable hard drive in bios e.g.)



if it boots and shows  /com.apple.boot.plist couldn’t be found - or smth like that, then it’s installed correct



if you doesn’t see any messages on such boot - repeat step PRIVET, or make this step from linux system,



using another drive name for of=

Migration step



U can also migrate with any utility u want(maybe, using another way to migrate,

u will have to repeat steps with installing boot1/boo0/pc_efi_v8 ), or u can just

install new leopard on fuid-ready disk(it will requires repeating bootlaoders installing

steps. here is simple example of migrating.

now boot your osx again,

and using root account make this



cp -Rfp /Volumes/MYOLDLEO/* /Volumes/MYNEWLEO/



where MYOLDLEW is name of partition where u have leopard isntalled

and MYNEWLEO is a name of partition (on guid disk) where u want to copy your installed leopard



this operation will take a time, depends on size of your leopard partition

after it u should be able to boot this partition with pc_efi installed to your

guid drive (boot from guid drive).



here is example of commands to install pc_efi_v8, this in the only EXAMPLE



./startupfiletool /dev/rdisk1s2 ./boot_v8



dd if=./guid/boot1h of=/dev/rdisk1s2 bs=512 count=1



dd if=./guid/boot0 of=/dev/disk1 bs=400 count=1

so the guy made a mistake with disk and rdisk ? http://forum.osx86scene.com/viewtopic.php?f=16&t=2520
on line: ./startupfile........................

need rev2 asap :) to many problems playing around with rev1 ! ! !
zeph go for it! (maybe someone give a more or less date-tipp when it will be released? or the status what u all working on or plan to release with rev2)

Xan: if you are still getting just the flashing cursor on boot this worked for me

download gparted live cd and boot it
changed osx drive to Boot
