DUMP
This command causes the contents of various 82596 registers to be placed in a memory area specified by the
user. It is supplied as a 82596 self-diagnostic tool, and to provide registers of interest to the user. The format
of the DUMP command is:

where:
LINK ADDRESS,
EL, B, C, I, S
D As per standard Command Block (see the NOP command for details).
OK
D Indicates error free completion.
Bits 19–28
D Reserved (0 in the 32-bit Segmented and Linear Modes).
CMD (Bits 16–18)
D The Dump command. Value: 6h.
BUFFER POINTER
D In the 82586 and 32-bit Segmented modes this is the 16-bit-offset portion of the
dump area address. In the Linear mode this is the 32-bit linear address of the dump
area.
Dump Area Information Format
#
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 compatible data will be marked
with an asterisk.
#
In 82586 mode the dump area is 170 bytes.
#
The dump area format of the 32-bit Segmented and Linear modes is described in Figure 35.
#
The size of the dump area of the 32-bit Segmented and Linear modes is 304 bytes.
#
When the dump is executed by the Port command an extra word will be appended to the Dump Area. The
extra word is a copy of the Dump Area status word (containing the C, B, and OK bits). The C and OK bits
are set when the 82596 has completed the Port Dump command.
