Hello,
A BlueSCSI PowerBook edition installed in a PB 550c will not reset properly at system shutdown or reboot if an external device that provides termination power is connected and powered up. Duplicate by installing a BlueSCSI device, then connect a CD-ROM or other external device that provides SCSI termination power (termination power is required for external SCSI devices). The system will boot, but after a shutdown or reboot, the dreaded disk with a question mark appears. Cycling power on the external device while the PB 550c is shutdown is a workaround. Apparently a device that provides termination power keeps the internal BlueSCSI alive after a system shutdown, and whatever process the PB 550c uses at startup to reset the SCSI bus (in Mac OS 8.1) isn't enough to reset the BlueSCSI device.
