IIRC the SCSI port of the 2400c can basically kill the powerbook if you hot plug a device into it. I'd be willing to bet you fried your I/O board. A SCSI device chain requires all devices to be powered off while devices are added to the bus. The exception is specific hot-swappable items, but they usually have a hot-plug subsystem that is independant of the main SCSI bus that connects them to the host computer. regards, -- --chuck goolsbee geek wrangler, digital.forest inc, bothell, wa <http://www.forest.net> list mom, mac-mgrs mailing list... <http://www.mac-mgrs.org>
