NOTE:
The shadowing verification method used for 80386 systems does not do a
complete RAM checksum. It only clears a special magic area in the
Standby SPE’s memory and then updates that area by shadowing. It then
verifies the value in that magic area based on the Active SPE’s value. Thus,
the test is not as comprehensive in terms of testing the memory aspect of
shadowing as is the 80286 method. The reason for this is the inability to
shadow flash memory.
