A few weeks ago, I finally made the transition to OS X Tiger on my B&W.
I did it by sticking a new, SCSI, hard drive in the Mac and installing
Tiger on it. I left the old OS 9 disk untouched.

Today, for the first time, I needed to boot back into OS 9 (there's a
CAD app that I use which won't run past 9.0.4, so it won't work in
Classic).

Using the "Startup Disk" panel, the boot back into OS 9 worked fine, and
when I was done, I opened "Startup Disk" to go back to Tiger.

The disk containing OS X was not an option!

Tried booting with "option" depressed -- didn't do anything useful; just booted from the OS 9 disk again. I did not see the "choose a disk"
screen that I've seen on my Pismo.

Tried booting from an OS 9 CD -- the OS X disk was not listed.

Finally, annoyingly, I had to unplug every disk except the OS X one, and
after a looooong delay, the Mac finally decided to boot from it.

Now, that's just not a very nice way to implement "dual boot". And I
know I'm going to need that CAD program again.

I suppose I should mention that while in OS 9, the OS X disk did not
mount; I don't know why.

What can I do to fix things?

Read the instructions for that setup: You need the _latest_ OS9 Startup
Disk panel, which will recognize the OS X disk as a valid startup disk.
For obvious reasons, versions before that didn't know about OS X and
wouldn't recognize it as a valid system.

See, e.g.: <http://docs.info.apple.com/article.html?artnum=106225>,
which begins: "You should update your Mac OS 9.1 Startup Disk control
panel to version 9.2.1 or later. Updating to Mac OS 9.2.2 is recommended
for best Mac OS X compatibility (applicable when both are installed on
the same computer)."

You can set the startup-disk in open firmware.

For an example see:
http://www.bombich.com/mactips/openfirmware.html

Snippet from this page:
" 1. Boot into Open Firmware (OF) by holding down the
Command+Option+O+F keys during startup.
2. Type "printenv" at the prompt
3. look for the boot-device setting. Write this down. Be
accurate, the command line is unforgiving.
4. Type the following, assuming
"mac-io/ata-4@1f000/@0:2,\\:tbxi" is your current setting:
5. setenv boot-device mac-io/ata-4@1f000/@0:2,\System\Library\CoreServices\BootX
6. then hit return. The only thing I changed was the "\\:tbxi"
at the end, everything else stays the same. Also note that these are backslashes, not forward slashes!
7. Type "mac-boot"
8. Rejoice, because you're booting into X. Hopefully everyone
gets to this step.
9. Now GO TO THE STARTUP DISK PREF PANE AND SET YOUR STARTUP
DISK. You'll notice that it is still set to the OS 9 System Folder.
That's because the GUI isn't designed to understand how we've tricked
it. Just set the startup disk to your X disk. If you typed "nvram -p"
in the Terminal before/after setting the startup disk, you'd see that
it removes the \System\Lib... stuff and replaces it with \\:tbxi."

But be carefull, what you are doing. You can really harm your system
while playing in open firmware.

Kind regards, Herlind

I just tried Startup disk v 9.2.6 (which was installed in my OS 9.2.1
folder). It could not see the OS X disk either.

One possibility is that there's no OS 9 driver on the new OS X drive.
Mac OS 9 and earlier loads the disk driver from a special hidden driver partition on the disk it's trying to read. Mac OS X no longer needs this driver, but if you format a drive using OS X's Disk Utility there is an
option to include it so OS 9 systems can still read the disk.

You can check if the driver is present with Disk Utility. In the disk
pane select the hard drive (not the disk volume under it, but the icon
with the hard drive model name) and click the Info button in the tool
bar. It should have 'Mac OS 9 Drivers Installed: Yes'.
