jrrjrr Posted February 15, 2007 Share Posted February 15, 2007 I have a new MBP. I used Boot Camp to install Windows XP on it. Now, I would like to do some experimenting with the OSX portion and I can't figure out how to get a "boot:" prompt so I can pass boot options (like -v or mach_kernel.test) like I can do on my Hackintosh. I tried editing com.apple.Boot.plist to add in QuietBoot=No and Timeout=5, but it still boots into OSX without showing a text screen for a few seconds where I can hit a key and then enter boot options. Best I can do so far is hit Command-s after the chime and boot into single user mode, but I really would like to be able to pass it alternate kernel names at this step also. Any ideas???

jrrjrr Posted February 15, 2007 Author Share Posted February 15, 2007 From doing some Googling, I think what I am looking to do is access Open Firmware when it boots. That normally gets you to a prompt where you can issue a "load" command for the kernel you want it to boot with and then a "boot" command to continue on booting it. The way to get into the Open Firmware is command-option-O-F from what I am reading, but that is not doing anything for me. I think some of this gets mucked with because of Boot Camp being in place. So still seeking help -- A way to pass an alternate kernel for it to boot with when you are a Boot Camp user? Link to comment Share on other sites More sharing options...

Open Firmware was cast out with PPC when the upgrade to Intel occurred. Link to comment Share on other sites More sharing options...
asap18 Posted February 15, 2007 Share Posted February 15, 2007 i think the best you can do is get to an efi shell. Install refit for that. Link to comment Share on other sites More sharing options...
jrrjrr Posted February 16, 2007 Author Share Posted February 16, 2007 Thanks for the Open Firmware to EFI info. It actually dawned on me that there was no more Open Firmware about 2 minutes ago. I can get cmd-v and cmd-s working now. I guess I had the wrong timing in attempts before. Also c to boot off a CD and t to boot into Target Disk mode work. But nothing I have tried gets me to any place to feed it boot options and the change to EFI must have depreciated a lot of the options that you used to be able to set in com.apple.Boot.plist.

jrrjrr Posted February 16, 2007 Author Share Posted February 16, 2007 Thanks for putting all these key commands in one place. I'm going to save this info for the future. I had not found half of the ones you've listed. Link to comment Share on other sites More sharing options...
