problems with live/boot cd

Postby Huntered67 on Sun Apr 06, 2008 12:22 am

ok so here is the thing, iwas having problems with my mint 4.0 distro, so i booted my cd of Gparted and got rid of all my partitions.

im trying to reinstall or even at least run mint on my computer and the CD is not booting correctly. it gets past the part where i choose safe mode or not, all the way until right after the loading bar part with the mint logo.

it says something about microcode5 (and some letters and numbers) failed, then it stops sending a video feed to my monitor and sits there doing nothing. any help?

(im pretty sure its not my computer, because im posting this whil im running Ubuntu from a liveCD

This may be a tricky error...
First - have you checked the md5sum and burned slowly. It may well be a bad CD
Second - do you have a Broadcom wifi chip? This is an error to do with the firmware/driver of bcm43xx
If your CD is OK we may have to be a bit geeky to solve the problem
Boot into recovery mode with the live cd. To do that, press F6 when you see the first splash
Delete "quiet splash --" at the line that appears and add "ro single" (no quotes)
Then start the boot - you will end up in Recovery mode as root
In here you will have to do some editing - it's not as hard as it seems, but if you are not used to a pure CLI environment it's a bit strange. Do the following (sudo not needed)
nano /etc/modprobe.d/blacklist
(Use the arrow keys to navigate)
Last in the file add
blacklist bcm43xx
Now continue - type
exit
(All commands in CLI to be followed by "Enter")
This should stop the driver from being loaded and boot should succeed

ok, i tried what you suggested, i added it to the blacklist etc etc

but every time i reboot, it just deleted it off, ive gone it several times and tried different options (write out, etc). i removed the wireles card i ahd in, just as a little extra precation seeing as i dont use it anyhow.. it has however stopped giving me the message that it failed to load anything, but after the loading bad is donw after the first splash screen, my monitor starts displaying "no input" then "out of range" and it switches back and forth on that a few times before just stopping alltogether

This is a live CD - you can't save anything....
You have to follow the guide I wrote each time
If you have the monitor out of sync there's things to about that too

Errg... I hate Broadcom drivers. So hard to reverse engineer, not to mention get able to work.

My first post describes how to - hopefully - fix this by blacklisting the driver so you can boot normally
