UPDATE 14 July 2008:

Can Darwin Bootloader boot another disk?

No, only the first 4 partitions where Darwin is installed.
EDIT: you can boot other Mac Disks wit boot-uuid flag: http://forum.insanel...howtopic=115636

Can I select Darwin Bootloader Default Boot Partition?

No, the default boot is the active partition.
It can not be changed with any configuration file, you can modify the source code if you want a different behaivor.

Which option does the Darwin Bootloader has?

See link: xnu-1228 / Boot Arguments

10x as usual for macgirl :D
I started to feel already about the fact that active partition is always default, getting chain0 file and using it in winxp boot.ini and changing the active partition to xp is a decent workaround. Second workaround is grub or lilo.

Typically Darwin/Mac OS can't work with Extended/Logical partition, but I seen some that have a working installation on them.

After Acronis Bootloader (need it for my wife and her vista). Ive got my darwin bootloader for my Leo4All v3.
Ive got 4 partitions 2 of the are active partitions (0,2 vista / 0,3 Leopard). But when darwin start up ask me to choose the system and always the default partition is 0,2 Vista Ntfs.

How do I change default startup disk to 0,3 Leopard??

And, after doing that, how do I turn darwin bootloader off (in case I need it afterwards).

I have perfectly installed Vista and Leopard with acronis bootloaded. (after more than 10 attemps!)
I cant screw my vista partition or anything else.

Can anybody help me with this??

Thanks a lot.

It is impossible to have 2 active partitions, if your partition manager says so it's weird, http://en.wikipedia....ter_boot_record

If you want to make Leopard the main OS when boot make the Leopard partition active.

If you want to do it within Leopard check this: http://forum.insanel...showtopic=22844

For dual Vista + Leopard: http://forum.insanel...showtopic=39253

I hope I am in the right place with my question. I have been reading throughout this forum but havent seen my same problem yet.
After I partitioned (FAT32) my (new) drive I rebooted to the (Kalyway 10.5.1 ) DVD and it loaded about 5 minutes , then flashed the white screen with a big grey apple for about a half second at most, then machine reboots. I have tried this more than once with the same result. I have tried it with -v although I don't get much chance to look at what the last thing loaded is due to the machine restarting .Do you have any suggestions? Any help you could offer me would be greatly appreciated. Thankyou for your time.

Thank your for information

I have just one question: How is it possible to reinstall darwin-booloader?

Why i ask this?: I've recovered my files to my boot-drive with "TimeMachine". (TimeMachine Backup was stored on the second partition) After recovering the system is not booting - it hangs while loading bootsector.
What can i do?

TIA

i have a triple booting situation with 2 xp and 1 macosx on the active partition...
it works with darwin boot loader...by default it boots mac if i want to boot xp i should press a key and then select another partition then i enter the xp boot.ini and select again which one xp i want...

problem is that i use xp much more then osx (i use osx only for 1 program) so i tried to change the active partition to the xp partition (apparently this is the only way to change the default boot in darwin until someone will edit the code, hopefully soon..)
then i tried again and ...darwin disappeared no more chance to boot osx....
so i modified the xp boot.ini with the chain0= system and now i have a first boot option menu from windows then i select mac osx , then enter darwin and then i have to press any key and then select AGAIN mac osx...

i wonder if there is any more clean solution with just one menu...ok not that big deal but still....

thanks
matteo

Dear All,
i am trying to clone my MAC OS X Partition before i am updating my system as a backup, i do this using super duper or carbon copy, as i have both.

i do the cloning on my USB2 external hard drive on MBR Partition which i erased it with 0 security option before the cloning.
my problem now that when i finish the cloning and try to restart from the external drive, i got this error

Boot 0 = MBR
Boot 0 = MBR
Boot 0 = MBR

Boot 0 Error

and i do not know how to fix this error

Thanks for helping

hey does anybody know how to extend the time for darwin to boot?
I'm trying to enter the flags in, but for some reason, it goes straight to loading OS X.

In /Library/Preferences/SystemConfiguration you should edit the com.apple.Boot.plist file. There is an option in the file for Timeout.

Just change the value between the <string> and </string> tags to how many seconds you want to wait.

Just a small detail:

I have a DualBoot Intel PC and Vista Boot loader works as default. This is only because it's the only way how i get it work.

And also, i must set Vista as flagged from fdisk.

When i boot, and choose Mac OSX from Vista boot loader, i come to Darwin. That's good, but how can i change Darwin's (Chameleon) behaviour so that it will boot choice number 1 (OSX) instead of choice number 2 (Vista and Flagged).

If i make OSX active, Vista wont boot at all.


Kari
