DFS D3.0

May 29, 1992

DFS release D3.0

*  This revision allows selftest to pass without a XE1201 modem chip installed.

*  User interface is now menu driven
  
*  New program TOMBSTONE for viewing tombstone files from the DFS
    invoked by using "x tombstone" from the "CLI>" prompt.
  
*  New program REWRITE for refreshing all data on a disk from the DFS
    invoked by using "x rewrite" from the "CLI>" prompt. For details and 
    a copy of the standard help dialogue, see below.
    
*  New IOP Kernels for 300C, 300S, 400C and 400S are provided. The following
    bug(s) was(were) fixed:
    
    PRS =>  9123690-0165-8/2,       
            9123690-0164-4
    CSR =>  5559 

    Software flow control om port 16 has been repaired.

*  New file created in DFS (200/300/400) which contains the date codes
   of the EEPROMS.  File name is EEPROM_REVS and can be read by using
   the DFS.COPY command,

    Dfs.Copy (Dfs_Filename => "EEPROM_REVS",
              Env_Filename => "EEPROM_REVS",
              Allow_Overwrite => False);

   which will copy the file to the local context, where it can then be viewed.

  REWRITE                

    This DFS program is used to rewrite a disk drive. It will attempt
to rewrite every header and data field on the disk in place thereby not
only refreshing the data but the header as well. Normally, the header is
only written at format time when running the DFS RECOVERY program.
The program allows for 2 modes of operation:
    rewriting a single disk    ( interactive mode )
    rewriting multiple disks   ( unattended mode )
    
When running in single disk mode, as correctable errors are encountered, the
program stops and prompts for user directions. In multiple disk mode, all
drives are configured to run at the beginning of the program and the user
can 'walk away' while the program ripples thru the specified drives.

A single drive dialogue follows, note that when really running, the 
cylinder line will increment as the program proceeds thru the drive.

The following is an example of running the multiple option and shows a typical
error report for an unrecoverable error. In the case of an unrecoverable read 
error, the sector is just left as it is. For correctable errors, the error is
corrected before the sector is rewritten. The true elapsed time may deviate 
from the estimated time based on the number of bad blocks encountered.
