NOTE
The 82596 is not Dump compatible
with the 82586 because of the 32-bit
internal architecture In 82586 mode
the 82596 will dump the same number
of bytes as the 82586 The compati-
ble data will be marked with an aster-
isk
These bytes are not user defined
results may vary from Dump com-
mand to Dump command
