Hi Charles,

Yes, I see your point. The thing is that still being newbieish to
both Linux and OS X, I don't fully understand this. Here is what I know:

Hi,

I am also very uncomfortable with macintoshes, but I have some
experience of debian. Maybe you can post your answer to this mail on the
mailing-list again, because there are experts reading it. But experts
are busy, they need to grasp quickly the informations to get in the mood
for a quick answer :)

What kind of mac do you have ? What is the result of cat /proc/ cpuinfo ?

1) I can boot into the Ubuntu HD with both drives connected.

How are they connected ? Master / slave ? Are they all SATA ?

Ubuntu (sda) is master, OS X (sdb) slave


2) Holding down the command-option-o-f keys all together after
pressing the power-on button does not bring up an OF prompt.

That somewhat strange. What about trying to press them all before
swiching on, and releasing them only when you see some text on the
screen ?

Yep, it was a keyboard issue. I have now changed the keyboard.

3) I can't bring up the graphic OF interface. Do you know the key
command combo? I thought it was just "o", but that didn't work.

I think it is just the apple key alone. Or the option one. But only
one.

It is the option key. Working now as per # 2. This is the only way that I can boot OS X with both drives connected at this time.

4) I mounted my OS X partition under Ubuntu and simply couldn't find
the kernel for some reason.

Why do you want to find the kernel ? Are you sure that you need to know
where the osX kernel is to boot osX ?

Just seemed to be the right thing to do when OF didn't seem to be able to find it.

I was looking on what is "sdb3" for me.

What is the result of /sbin/cfdisk -P t /dev/sda ? /sbin/cfdisk -P t
/dev/sdb ?

I think there was something wrong with the command variables wasn't there? Here are the results:

$ sudo /sbin/cfdisk -P t /dev/sda
Password:
FATAL ERROR: No partition table.

~$ /sbin/cfdisk -P t /dev/sda
FATAL ERROR: Cannot open disk drive
$ sudo /sbin/cfdisk -P t /dev/sda3
FATAL ERROR: Bad signature on partition table
$ sudo /sbin/cfdisk -P t /dev/sda
FATAL ERROR: No partition table.

$ sudo /sbin/cfdisk -P t /dev/sda2
FATAL ERROR: No partition table.

$ sudo /sbin/cfdisk -P t /dev/sdb
FATAL ERROR: No partition table.

$  /sbin/cfdisk -P t /dev/sdb
FATAL ERROR: Cannot open disk drive


5) I have created and "mnt/hfs" folder in Ubuntu, I just don't
remember how to get the partition (sdb3) to mount automatically.

Me neither :) Maybe you would better mount it manually for the moment.
Is it listed in /etc/fstab ?

The only other thing I can think
of is when I do get an OF prompt, to try a string like: boot: sd:3,/
vmlinux root=/dev/hda3 ro. That assumes that "sd" stands for a SATA
drive in OF.

I am getting confused : do you want to boot linux or osx ?

My problem is getting OS X to boot.

Cheers,

Brian
