Darwin’s promt: * -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 * -F Ignore configurationfile * 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 Boots OS X in 32bit mode rather than 64bit if 64bit is used due to a 64bit processor * idehalt=0 May stop stuttering * “Graphics Mode”=“WIDTHxHEIGHTxDEPTH” (e.g. “1024x768x32”) For VESA 3.0 graphics, you may append a refresh rate after an “@” character (e.g. “1280x1024x32@75”)
