Gringo Vermelho 1,064 Posted February 22, 2013 Share Posted February 22, 2013 For anyone with a stuck boot-flag, you can do this;sudo nvram -d boot-args Or, while at the Chameleon GUI press the TAB key. Then remove any undesired boot args or flags from the command line and press enter to boot normally.Click here for more information. Also see here (thanks nyolc8). 2 Link to post Share on other sites More sharing options...
theconnactic 1,109 Posted February 22, 2013 Share Posted February 22, 2013 Just adding to what Gringo Vermelho said: or just start typing something at the boot menu, then the stored boot flags will appear and you can just delete them with the backspace key, finally typing the ones you want to use (or none at all, but in this case you'll need to do it every boot). I just learned it's fixed. Link to post Share on other sites More sharing options...
nyolc8 138 Posted February 22, 2013 Share Posted February 22, 2013 With this version, my autogenerated ROM value is became this: "i%1b(%e0%96%00" This is nothing related to my MAC address, none of the characters are in my MAC address, and what the hell is that "(" in it? Bug in the auto ROM value generator? Link to post Share on other sites More sharing options...

nyolc8 138 Posted February 22, 2013 Share Posted February 22, 2013 Really? I thought it's the MAC address... but is that "(" character good there? It looks really strange. Link to post Share on other sites More sharing options...
meklort 118 Posted February 22, 2013 Share Posted February 22, 2013 It's a random number. If it happens to be equivalent to an ascii printable character, it'll print out as that char (such as the '('). If not it'll print out as hex (%NN) The value is the the same either way, it's just how nvram is printing it for human readability. Link to post Share on other sites More sharing options...

If it's that way for the sake of aesthetics (because it's not readable either way in the end), i really think printing as a hex string is a better choice. Best regards!

mitch_de 304 Posted February 24, 2013 Share Posted February 24, 2013 Sorry, but i am a bit a "noob" for that nvram usage If i use nvram -p command - without that module installed - to show variables i get : GA_EP35:~ andreasm$ nvram -p SystemAudioVolume 0 fmm-computer-name GA_EP35 If i would use / install that nvram module (with chameleon 2181+) what new variables would exist / what would be changed / what things may work better? Or, if no new nvram variables are automaticly created by the module, which variables maybe usefull to create + use? Link to post Share on other sites More sharing options...

ameris_cyning 255 Posted February 26, 2013 Share Posted February 26, 2013 A little feedback: Something is wrong. My Wifi no longer connects to a wifi network when it hits the desktop (it connects a few seconds after hitting the desktop). Not only this I have to wait between 45 seconds to a minute for my bluetooth dongle to work when I hit the desktop. Link to post Share on other sites More sharing options...

Or, if no new nvram variables are automaticly created by the module, which variables maybe usefull to create + use? Here's how I understand that (If I'm wrong please correct me): OS X saves some settings in NVRAM (Non-Volatile RAM). PC doesn't have that. So every boot these settings are restored to default values. This module writes and restores them from a file created in /Extra directory. So for example, after reboot it will remember your volume settings, brightness value (on a laptop), etc. It can fix iMessage issues, probably also Find My Mac.

rcork 31 Posted February 26, 2013 Share Posted February 26, 2013 Any chance the module will ever be able to detect when the boot-args stored in the plist differ from those in org.chameleon.boot.plist and give precedence to the boot.plist? Link to post Share on other sites More sharing options...
meklort 118 Posted February 26, 2013 Share Posted February 26, 2013 The boot-args are in addition to whatever is in the plist. If you don't want one, just set it using nvram boot-args="-v other flags" or delete it with nvram -d boot-args. Alternatively you can update the boot args in chameleon by updating the command line.

I get what you're saying but most people are used to updating boot args by editing org.chameleon.boot.plist. This module changes that process and it would be good if the module obeyed what has always been the way to set boot parameters instead of forcing users to learn a new way. If its technically not possible based on the chameleon module architecture then that's one thing but if possible, it would be good to have the option. You could always open source the module and let other developers add that capability ;-) Link to post Share on other sites More sharing options...
meklort 118 Posted February 27, 2013 Share Posted February 27, 2013 We do plan on eventualy releasing source for the module, however those plans are not for the immediate future. In any case, enough information is distributed with the module to modify and extend it's behavior. We include the FileNVRAM.h header in the distribution to allow for any developer to create a module that extends this one. Three API function are defined, get, set, and delete NVRAM variable. Using these functions you can do things such as check if the machine has been locked by FMM, check the default partition that was set by the Startup Disk utility in os x, or anything else that you can think of. In the case of boot-args, the FileNVRAM module registers for a notification to the BootOptions hook. If you wish boot-args to not be set (or to be set to a specific value), you can pose as the original caller of that hook and inject your own data.

meklort 118 Posted March 6, 2013 Share Posted March 6, 2013 are the chameleon boot loader project dead ? cosmo1t and I do not have much time to work on chameleon and took ourselves off of the project. There are still users with commit access who can develop it as needed, however commit activity is very low. i got this plist in the extra folder nvram.ffffffff-ffff-ffff-ffff-001xxxxxxx.plist. what does these ffff meaning? The UUID was read directly out of the machine's SMBIOS, it's whatever your computer's manufacturer set it to be. Link to post Share on other sites More sharing options...
