Hi.

I googled a bit but could not find any information on this topic.

Which files configure the Darwin Boot Loader? I want to reduce the wait time ( 8 seconds actually) and change the default partition from Mac OS X to Windows.

Does anyone know which files I have to look at or where I can find information regarding this topic?

Greetings and thanks in advance,

Shizo

To set the timeout time, go to "/Library/Preferences/SystemConfiguration" and edit "com.apple.Boot.plist".

Add this before the </dict> tag:

<key>Timeout</key>
<string>#</string>

Where # is the number of seconds you want.

You can also add other boot parameters here (like platform and Quiet Boot) but I don't know if there is one for setting the default partition.

For the default partition, you might want to look into...

changing the text:
   <key>Kernel Flags</key>
    <string></string>
to be:
   <key>Kernel Flags</key>
    <string>rd=disk0s1</string>

from the same file in
/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

I have not personally tried this, so post your results if you try it out.

Thank you both for your answers.

the boot option "rd=..." doesn't work. it just brings up the mac start streen with an error message.

Isn't this for selecting the root partition, ie. where OSX is, or which one to boot?

boot with leo disk is, than F8, and enter in single user mode by pressing '-s' without the quotes.

from dere use the fdisk string to flag your appropriate partition.

I have 2 installs of osx, one works perfectly, the other is a copy of it on another disk, made with super duper.

the darwin boot loader sees the copied version as being a foriegn os and not bootable

how do I change this? I need to make bootable backups as a routine thing!
