                      2: Testing of read access with Dosemu
                      3: ==================================
                      4: 
                      5: 
                      6: I describe the method I use for my drives, you may need to change some names.
                      7: I have a DOS filesystem on /dev/hda1, I usually mount it on /DOS.
                      8: This drive is seen as c: from DOS when starting.
                      9: Stacvol file is c:stacvol.dsk. When config.sys is executed
                     10: stacvol.dsk is swapped and becomes c: and old c: is d:.
                     11: 
                     12: Prepare dmsdos package in /usr/local/src/dmsdos-x.y.z/src
                     13:   rmmod dmsdos      # for changes from next compilation
                     14:   make clean
                     15:   make
                     16:   insmod dmsdos
                     17:   cd /DOS
                     18:   mount -r -t msdos -o loop stacvol.dsk /mnt  # important: mount READ-ONLY!!!
                     19: 
                     20: Now you should see the root of your DOS drive in /DOS directory and
                     21: under /mnt the root of your stacker drive.
                     22: In the syslog you can see the parameters of all mounted stacker drives.
                     23: If you have dutil compiled, you can proceed the next test
                     24: 
                     25:   dutil /mnt checkfs
                     26: 
                     27: If there are errors you can see them in the syslog as DMSDOS: ...
                     28: Now you can make the read test.
                     29: Configure Dosemu for readonly access to the full hard drive or partition.
                     30: 
                     31:   disk { partition "/dev/hda1" readonly }  # must be first to boot from it
                     32:   disk { image "/var/lib/dosemu/hdimage" } # or something similar
                     33:        # you need this to have access to dosemu utilities
                     34: 
                     35: You must include somewhere in config.sys line
                     36: 
                     37:   device=<hdimage_drive>:\emufs.sys /
                     38: 
                     39: Now run Dosemu by command
                     40: 
                     41:   dos -C
                     42: 
                     43: If it does not work try to find out if stacker can see its stackvols.
                     44: There may be differences if you have some other organization of the drives
                     45: under DOS. 
                     46: Now you can see or change redirections to the Linux filesystem
                     47: 
                     48:   <hdimage_drive>:lredir 
                     49: 
                     50: For comparing you can use the dos utility cmpdisk.exe, which tries read all
                     51: files from two drives. One should be the drive managed by regular
                     52: dos stacker and the second by the Linux dmsdos driver.
                     53: 
                     54:   cd <stac_drive>:\
                     55:   cd <redirected_linux_drive>:\mnt
                     56:   cmpdisk <stac_drive>: <redirected_linux_drive>:
                     57: 
                     58: If some file is read differently from one drive, cmpdisk waits
                     59: for a keystroke. Then it continues. Parameters of cmpdisk can
                     60: be in form:
                     61: 
                     62:   <drive_letter>:[\]<directory>\ 
                     63: 
                     64: for example
                     65: 
                     66:   E:\mnt\
                     67: 
                     68: Any differences are suspected to be dmsdos bugs!
