Hey there! Basically... my dad has a very old and fragile machine running 10.3, the internal hard drive is on its last legs so he wants to boot from an external drive. We've got a bootable external hard drive set up, and we select it in Startup Disk and restart.... is there any way to verify it's actually booted from the external drive? In later OS X the boot drive can be found in "About this Mac" but not so in 10.3 .... so is there anything in terminal that can help? Should be an easy answer to this, I just dont know what it is! Thank you!!
