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 https://www.insanelymac.com/forum/topic/40213-darwin-bootloader-switches/ 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 https://www.insanelymac.com/forum/topic/40213-darwin-bootloader-switches/#findComment-287092 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...

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.

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 https://www.insanelymac.com/forum/topic/40213-darwin-bootloader-switches/#findComment-288949 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 https://www.insanelymac.com/forum/topic/40213-darwin-bootloader-switches/#findComment-291466 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 https://www.insanelymac.com/forum/topic/40213-darwin-bootloader-switches/#findComment-295220 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.
