Sample System Error Report (Uerf) - DEC 4000 AXP Service Manual

4.4.10 Sample System Error Report (UERF)

Example 4–2 provides an abbreviated UERF-generated error log for a processor
machine check, SCB 670 ( ).
The low quadword of the error field register, ERROR FLAG1 ( ), has two bits set.
The corresponding bit-to-text translations may not be provided for some versions
of DEC OSF/1. The high quadword of the error field register, ERROR FLAG2 ( ),
has no bits set.
The following analysis of the error field is helpful in finding the
corresponding bit-to-text translation in Table 4–2.
ERROR FLAG1 corresponds to quadword 0; ERROR FLAG2 corresponds
to quadword 1.
The error field bits are arranged in four-character words (0–3, right to
left); for example,
ERROR FLAG1 x|0000|0008|0000|0005
