D.2 Bugcheck Packets
Bugchecks occur because of some kind of software detected fatal failure. For
example, a hardware failure, or an internal system consistancy failure might cause a
bugcheck. These events cause Bugcheck packets to be written into EEROM. Refer to
Figure D-2 for the detailed packet layout. The most important information is the
error code. The more common ones are listed in Table D-2. A full listing is not given
here because most are not meaningful without a detailed knowledge of the firmware
design. Analysis of the other informtion saved in an EEROM Bugcheck log entry
also requires in-dpth internal firmware knowledge to interpret and attempt to
determine if the cause was external (e.g. a bad SCSI bus cable, improper
termination, etc.), an ECM or drive fault, or a firmware bug.
