i have had this external hard drive set up a while ago with bootable partitions of 10.6, 10.5, and Disk warrrior. Though i recall many new macs will no boot to it due to some firmware changes apple has been making. I am wondering if anyone who is knowledge on this topic could tell me what machines stopped supporting external boot devices (unless its the apple restore CD)

thanks guys

None, you just need to keep your 10.6 install updated. Update it to 10.6.6 and it will boot all Intel Macs, past and present.

art i meant to say so the computer would be able to boot of the device, and be used as an installer / disk utility, not used solely as an additional boot option to operate the OS.

Am I making sense?

I know what you meant. My answer still applies. Apple has not changed the firmware of current Macs to disable booting from an external drive. You need to have at the minimum the same version of the OS as what the Mac shipped with.
