Guys, here's what you need to do; go to: http://www.freebsd.org/handbook/kerneldebug.html Basically you need to compile a kernel with: options DDB options BREAK_TO_DEBUGGER #a BREAK on a comconsole goes to then when it hangs at boot one might be able to to hit ctrl+alt+esc to get into the kernel debugger, then hit 't' (i think, it's been a while :) ) to get a traceback. Tell us what you see. Another simpler option is interrupting the boot countdown and typing 'boot -v' to get a more verbose boot then give us more information than just "isa0: <ISA bus> on motherboard". :) Please let us know what you find out. thanks, -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."
