edmoncu Posted January 28, 2007 Share Posted January 28, 2007 Hi there, I have tried searching from the forum but came up empty handed... As I remember, someone posted switches available to use on the Darwin bootloader. I hope someone could help me at this. Thank you very much in advanced! :pirate2: Link to comment Share on other sites More sharing options...
user1453 Posted January 28, 2007 Share Posted January 28, 2007 -s to go into single user mode (a comand line interface -v to go into verbose mode (tells you what it's doing whilst loading the os -f to go into safe mode Link to comment Share on other sites More sharing options...
gotoh Posted January 28, 2007 Share Posted January 28, 2007 -F will force boot without using extension caches (so it will rebuild it) -x is safe mode... Link to comment Share on other sites More sharing options...
Neonkoala Posted January 28, 2007 Share Posted January 28, 2007 http://neonkoala.co.uk/content/view/33/34/ Quite a lot of information on using the bootloader there. Link to comment Share on other sites More sharing options...

edmoncu Posted January 29, 2007 Author Share Posted January 29, 2007 (edited) quoting your article... it says... * -f - This forces rebuilding of extensions cache * -s - Boots into a single user command line mode * -v - Verbose, boots in text mode showing all debug info and errors * -x - Boots into safe mode * "Graphics Mode"="1024x768x32" - Tells VESA to boot with this resolution, the x32 is bit depth and is only compatible with VESA 3.0 and up * rd=disk0s1 - Tells Darwin to boot from a certain partition specified in BSD format. Disk 0 specifies first HDD and s1 specifies first partition as 0 is the MBR. * cpus=1 - Tells the system how many CPUs or cores to use, useful for Core Duo users. * platform=X86PC - Can be used if problems with normal booting, ACPI is another option here * -legacy i have a question though... you said that the switches can be made permanent by accessing terminal and typing sudo -s nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist if for example, i am to save the setting "-cpus=1" to the said file, would i enter this on the said file? <key>cpus</key> <string>1</string> or if i want the kextchache to be always rebuilt at startup, i add this code? <key>f</key> also, should i enter all entries inside the <dict> part? and are they all case-sensitive? awaiting for your feedback here. thanks again! thanks.

Neonkoala Posted January 29, 2007 Share Posted January 29, 2007 <key>Kernel Flags</key> <string>cpus=1</string> <string>-f</string> That should take care of it. Make a backup just in case though. Link to comment Share on other sites More sharing options...
edmoncu Posted January 30, 2007 Author Share Posted January 30, 2007 <key>Kernel Flags</key><string>cpus=1</string> <string>-f</string> That should take care of it. Make a backup just in case though. i see... does it have to be inside or outside the <dict></dict> or <plist></plist> portion of the config file? thanks Link to comment Share on other sites More sharing options...
edmoncu Posted February 2, 2007 Author Share Posted February 2, 2007 btw, may i know what does the -legacy option do? Link to comment Share on other sites More sharing options...
edmoncu Posted February 6, 2007 Author Share Posted February 6, 2007 it seems this sheds a little bit light to the problem... Link to comment Share on other sites More sharing options...
jaminmc Posted February 6, 2007 Share Posted February 6, 2007 btw, may i know what does the-legacy option do? It boots in 32bit mode instead of 64bit. Will make OSX run slower. Link to comment Share on other sites More sharing options...
