Help Ubuntu 11.04 broke my macbook6,1 NO FIX

[zaebo]

Question, were you trying to access fs0 through the EFI Shell or while booted on Mac or booted on a Mac install disk?

Through the EFI Shell. I reinstalled rEFIt, after deleting it at the beginning.

Do I first need to mount the required partitions?

And can't I use my mac partition as the target location for the text-output?
Or what kind of output will it be?

I'm sorry, all of this is new for me and a mixture of missing knowledge and fear

[zaebo]

Ah, ok.
It worked.

Hey guys,
I have the same problem as zaebo iMac(10,1).
I tried bless flashing the firmware from /usr/standalone/i386/. No dice.

I tried to do
dmpstore BootFFFF > fs0:\bootffff

but I don't know how to get the dump file to show you guys.
I will be monitoring this thread and happy to do anything to sort this out..

[zaebo]

First of all...I'm sorry to read that

As johnmurrayvi said, fs0 direct the output to the hidden EFI partition.
So what I did to get it was:

(taken from here: https://bugs.launchpad.net/ubuntu-re...89/comments/94)

1. While in MacOS, create a folder to mount the EFI partition to.
For example, I created it on my desktop, but you can also create it elsewhere:

sudo mkdir /Users/Your-Username/Desktop/efi

2. Use the folder as mount point for the EFI partition and mount it:

sudo mount -t msdos /dev/disk0s1 /Users/Your-Username/Desktop/efi

3. Then you can access the EFI partition and copy the output file.

4. Umount the partition:

sudo umount /Users/Your_Username/Desktop/efi

The unmounting can take a few seconds...at least with my mac..

Thanks.
attached is the output.

I think I will run Ubuntu on my old peecee until this thing is sorted out. I have a working Macbook 2,1 and would like to keep it that way.

I'm sorry you guys are having issues, but thank you so much in posting here. I will keep this thread bookmarked in case someone finds a good solution.

I just restarted my iMac today and it started doing some sort of firmware thing!
Grey progress bar below apple logo.

It didn't seem to finish but booted into Lion....and then showed me the login screen (I never set the login screen in my preferences I think firmware changes some settings). When I logged in, there were all these weird graphical errors.

I restarted to see if it was fixed...but then it went back to normal...long beep button pressing game and no login screen.

[zaebo]

That sounds strange!

Do you still have the same ROM-version? Mine (with Snow Leopard) is:

IM101.00CC.B00

Just checked out if there is an EFI update availible, but
can't find anything. Neither in the software-update-app nor
on the apple homepage.

I'm hoping that soon some of the better informed poster are finding
back to this thread

[edwinorc]

Yep same Boot Rom.
Maybe around December I will have time to take my iMac to the apple store...

I REALLLLLY hope this issue gets worked out soon!

I ruined my MacBook 6.1 today by trying to install Ubuntu on it.. I even wiped my hdd, and reinstalled OS X... I also tried a different hard drive. Still takes 5 tries to boot up.

I'm so upset! $999 POS
