Boot Process for older computers...
...also, the boot process for older computers doesn't allow for pressing "option" at startup. Unfortunately, the only Macs that do allow are all of the newer AGP-flavored variety, but I could be wrong. All I know is that hitting option does not work on my B&W G3/450 at home or my iMac (rev. 3?) at work.
Quickly setting boot device on Mac OS X
There are a few Open Firmware variables that control booting. The ones I know get changed (which exact ones depend on your Mac model) are 'boot-device', 'boot-command', and 'boot-args'.

Argh, sorry, there should be only two backslashes there (\\:tbxi). Turns out you need 4 backslashes per backslash in preview, but only 2 in post.
Don't just copy this!!! It differs from system to system.
These values can differ wildly based on your drive setup, the revision of the machine, and whether the ROM is new world (everything with AGP) or old world (everything not AGP).
Use the nvram -p command in the terminal to find out the differences.
Here is a link to a thread at macosx.com where I detail this process.
