3.1.1 DZ Explanation In Configuration Table
The DZ has six 8-digit numbers that contain lhe status of the four serial
lines, the keyboard, and the mouse or tablet. Any 8-digit number other than
00000001 for the four serial lines and the keyboard indicates a failure on that
line. A status code of 00000000 for the keyboard indicates that the keyboard is
disconnected. The sixth 8-digit number is for the mouse or tablet and any other
code
than
000012AO (good status) or 00000000 (nothing connected) indicates
a failure in the device connected. Figure 3-2 shows what each 8-digit number
represents.

3.1.2 MEM Explanation In Configuration Table
The code for MEM in the configuration table indicates the amount of memory
available if no errors are detected. For example, 0010.0001 indicates that 16
Mbytes of memory are available (10 in hexadecimal
=
16). The second MEM
line in the configuration table contains two 8-digit codes, one of which is
not displayed when no errors are detected. The first code repeats the amount
of memory
in
the system and the second code (displayed only if an error is
detected) contains the location of the failed memory.
Figure 3- 3 shows the second 8-digit number of the MEM display in the
configuration table. The 3 in the last digit indicates the error is on the system
module. A code other than 0 in the last digit indicates an error on the system
module. A code other
t.
h an 0 in the other seven digits indicates an error on a
memory option module.
