How to find a specific UEC
The first hex digit of the UEC indicates the error severity, e.g. Fxxx codes are for hard/unrecoverable errors, 1xxx codes are for
soft/recoverable errors, etc. The second hex digit indicates the grouping, e.g. interface, media, servo, etc. types of errors. The
table is sorted without regard to the first hex digit; instead, sorting is by the least significant three hex digits.
