    Default How to enable/disable verbose boot (just for fun of course)
    Okay, so you're a geek like me and you like watching all your gear boot up in verbose mode....

    Option 1 - auto boot in verbose mode using terminal
    - launch terminal
    - type
    Code:
    nvram boot-args="-v"
    - press return
    - type reboot

    to disable
    - launch terminal
    - type
    Code:
    nvram boot-args=
    - press return
    - type reboot

    Option 2 - using tapp to enable/disable
    -launch tapp
    -enter the above commands on seperate tapp lines
    -enter reboot on a third tapp line
    -click save
    -click execute mode
    you can now enable/disable verbose boot with tapp

    If anyone knows of anyway to slow down the output...please let me know!

    Really? No one enjoyed watching this fly across their screen during boot?

    What ever you do... don't change the autoboot parameters to false....

    Nate true captured this on video: http://cre.ations.net/blog/post/ipho...tured-on-video

    He also typed it by hand so you can read it.

    Saw that, but this is different. His video is of a verbose restore mode. My instructions will just do a verbose boot every time you turn on/reboot your phone.

    no use really, as opposed to his verbose restore.

    I just think a verbose boot looks cool.

    it will be useful to store the lines on a file to read them and fixing errors... there is a way to do this?

    the iphone stores the boot logs somewhere? (I haven't found on log and Logs folders)

    First il leave a warning that Amnesia must have had amnesia about when he posted. Break your nvram on a mac and you will have a brick, so I am going to safely say that the iphone is similar I don't think any firmware update from apple will fix a broken nvram (Please correct me if im wrong anyone) so be careful and type slow.

    So after reading this, I decided I wanted to dig deeper and see if we can do anything else with nvram.

    Seems like we might be able todo more then just enable verbose mode.
    If you run this command: nvram -p
    in terminal on the iphone you will get something similar to this im sure. (This is mine after adding the -v)
    This is all the variables already set in nvram.

    backlight-level 40
    bootdelay 0
    filesize 14474
    auto-boot true
    boot-args -v

    You might be able to use the following command to slow down bootup and see errors and etc: nvram bootdelay="3"
    I am too much of a wuss to try it, but I don't see any reason it would hurt anything.

    I also found this site, http://www.mamiyami.com/document/ore...ac/ch08_03.htm with a listing of mac nvram variables.

    Theres a bunch in here we might be able to use such as, boot-device we might be able to change this and boot off a USB device, default-client-ip plus a few other variables to enable diskless booting, or oem-logo and oem-banner to show our own logos at bootup.

    Edit:
    Ohh and just found a site for making oem-logos
