Peter Wendt did the first incarnation of this page, but I am trying
to make it better.
This section provides an explanation of the encoded SCSI
and non-SCSI POST errorcodes and detailed information about each code.
Error messages are displayed on the screen as three, four,
five, eight, twelve or thirteen digits. An X in an error message can be
any number. Some digits will represent different information for SCSI errors
versus non-SCSI errors.
The Slot-Number is always given on the 12-digit errorcodes
for adapters; the Bus-code is shown on device errors in 8-digit error-codes.
The Slot-number is then omitted.
The most important and complete infos about the nature
of an SCSI-error is however given from the Advanced Diagnostics.
As an example, if you have SCSI error code 021050A0, each digit decodes
as follows:
