===============================
1 ATTACH
           The ATTACH command is  used  for  specifying  descriptions  of
           devices existing on the system under test.  A device cannot be
           accessed by a diagnostic program  unless  it  has  first  been
           attached.

           Attaching a device generally consists  of  issuing  a  set  of
           ATTACH  commands  so that a series of links can be established
           from the processor to the device.  The link that is closest to
           the  processor  is  a  pseudo-connection  known as "HUB".  All
           devices must be ultimately linked to  HUB.   This  concept  is
           illustrated by the example below.

1 SELECT
           Selects devices for testing.  A diagnostic program  will  only
           test  devices  which have been selected.  Devices specified in
           the SELECT command must have been previously ATTACHed.

     Format:

           SELECT DAA, DAA0, DAA1

1 DEVICES
       EVRMB supports DA devices

1 EVENT

       If event flag 2 is set, then the operator will be prompted
       for number of retries and whether to continue the test or
       abort the program and also questions to include area tested
       in some tests.

1 HELP

The RC25 front end host diagnostic (EVRMB) is designed to test the
RC25 disk drive subsystem.  Tests are performed to verify that:

a) The processor can properly communicate with the controller thru
   the adapter card.

b) The RC25 drive can seek and head select properly.

c) The RC25 conforms to the specified seek and rotational times.

d) The RC25 controller can perform certain basic functions in
   response to MSCP commands.


For each of the folowing parameters, type "HELP EVRMB parameter"


1 QUICK
There is no quick flag usage employed by this program.

1 SECTION
Defines the formatter sections (/SECTION qualifier on RUN or START)
which this formatter supports.  This formatter host code supports 
only the DEFAULT program section.

1 UNIT
One RC25 unit (UUT) is defined as a single platter. There are two
platters on one spindle in an RC25 drive. The RC25 controller may
have either one or two drives (two or four platters). The unit
number for the RC25 platters come in pairs. The removable media 
has an even number and the fixed media has the sequentially following
odd number. A maximum of 16 units can be tested in sequence.

2 DEFAULT
This section will run all tests with the exception of manual test.

To run this section type:

        RUN EVRMB                       or
        RUN EVRMB/SECTION:DEFAULT       or

or you can type:
   
        LOAD EVRMB                      then
        START                           or
        START/SECTION:DEFAULT           or

2 CRD
This section will run tests intended for CRD.

To run this section type:

   RUN EVRMB/SECTION:CRD
or you can type:

   LOAD EVRMB
   START/SECTION:CRD

2 MANUAL
This section will run operator intervention test. This test is not
implemented in this revision.

1 SUMMARY
   EVRMB does not give summary report.
