I have a Western Digital external drive hooked up with firewire 800

it for the start up drive, another drive will boot. If I use T on
startup I get a blue screen with a dancing nuclear icon. What am I
doing wrong?
You're booting into Target Disk Mode which effectively changes your
entire G4 into an external HD so that its HD can be mounted on another
Mac. You've got two external HDs attached to each other with no Mac to
boot from.
What you need to do is use the Option key at startup to select the
FW800 HD as the boot drive. You could also boot normally and use
Startup Disk to designate the FW800 HD. This will only work IF the G4
came with built-in FW800, you normally can't boot from an add-in FW800
PCI card.
