Change startup ?


2 posts in this topic

I would like to know how I can modify the startup. Now I have to wait 5 seconds before it starts loading Leopard, and I would also like to set it to start in verbose mode as default (-v).


Thanks in advance.

Open Terminal from the Utilities Folder, then run this:

sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

the system ask for your password, then add the flag you want: (taken from the osx86 wiki)


To automatically use a certain graphics mode

<key>Graphics Mode</key>


Note: If your video card is using VESA 2.0 drivers, leave out the '@85' part as it only works on VESA 3.0 will cause the system to reset before getting anywhere.

If you need to specify a platform

<key>Kernel Flags</key>

<string>platform=X86PC</string> or <string>platform=ACPI</string>

If you experience stutter like (shutter) syndrome; usualy on dual core processors

<key>Kernel Flags</key>

<string>idlehalt=0</string> or disable one core <string>cpus=1</string>

If you don't want to see the Darwin text on boot - HINT: You can get the prompt back by holding "ctrl" at boot.

<key>Quiet Boot</key>


If you want to show the Logo with spinning Boot Graphics

<key>Boot Graphics</key>


To put in switches (-v, -x, -s, etc)

<key>Kernel Flags</key>


Speed up Darwin's timeout count-down



Replace 8 (default seconds) to a new value.

To set Darwin to boot from a particular partition:

<key>Kernel Flags</key>


Where X is your hard drive number and Y is the partition number (BSD naming scheme)

if you are unsure about the rd value open Aplications>Utilities>Disk Utiliy, click on the partition with OSX installed and click on info, the right "rd" value is the value from "Disk Identifier"
