Re: MacOSX & Debian dual boot questions...
I have Debian and Panther on a G4/350, but I have the luxury of having 2
internal HDs, which might be more difficult with a PowerBook. Anyway, I
first installed Panther on hdb and used Disk Utility to wipe hda clean of
all partitions. Then I unplugged hdb so that there was no way the Debian
installer could *$!@ with it, and installed from a set of 14 Sarge testing
CDs. After reconnecting hdb, the small bootstrap partition on hda is still
the first blessed partition on the system, so yaboot is loaded first and I
get the dual-boot menu.
The main reason I'm writing this note is because I got into a little bit of
nastiness when I needed to upgrade OS 9, which I use 99% of the time from
the Classic environment in Panther. In order to update QuickTime in OS 9,
I had to use the "Startup Disk" control panel and choose the OS 9 system
folder to reboot into pure OS 9. The problem is that this process
"unblessed" the bootstrap partition on hda, and I no longer had the
dual-boot menu to get into Linux.
I found a "bless" shell command in Panther, but found its man page
confusing and I didn't really want to fry my whole system. I'm not even
sure if this command would bless a non-Apple OS partition, anyway. So I
booted from the first Debian install CD, started the installer, and went
through to the partitioning phase. At that point, I chose manual
partitioning, and told it NOT TO TOUCH any of the existing Linux (or
Panther) partitions except swap, then went to the next step, which is, I
think, the point where you must give the final OK to install the base
system. At this point, I kept selecting "Go Back", until I had the option
to abort the installation, which I did. After that, I rebooted, and voila!
the bootstrap partition was re-blessed, and I had my dual-boot menu
I admit that the process is a little hairy, and I probably wouldn't have
done it if I had anything really important on that machine. Does anyone
out there know of a "less hairy" way to reliably re-bless a bootstrap
partition? New-world macs, as far as I know, won't boot from an external
USB floppy drive, so the only way I can think of is to make a bootable
Debian CD with yaboot on it, set to boot the root partition on the HD. Any
hints on how one would create such a "rescue disk"?
I am wanting to install Debian on my PowerBookG4 but I am confused...
Should I (in OSX) repartition and leave a blank partition (for Debian),
reinstall MacOSX, then install Debian? If so how does my Mac know to use
yaboot instead of proceeding down OSX's 'boot path'? I have intalled just
Debian on a G5 and it works GREAT but I am confused and apprehensive about
doing a dual boot install w/ OSX. Any suggestions and insights are much
Thanks in advance as always!!!!
