- When Merge is installed, it automatically tries to link /dev/dsk/dos
- to the UNIX device that is the primary DOS partition, which is normally
- /dev/dsk/0s5 on SVR4.0 systems. Some versions of UNIX have trouble
- connecting a device file (such as /dev/dsk/0s5) to the DOS partition,
- expecially when the DOS partition was created/formatted after UNIX was
- installed. For this problem you need to call the UNIX support.
-
- Merge automatically uses /dev/dsk/dos for drive E:. If /dev/dsk/dos is
- linked to a properly working UNIX device name for the DOS partition, with
- the correct permissions, then it will work.
- If you have other DOS partitions then you can also attach those to
- any drive letter from E to I.

- This is not quite correct. The default is "+amouse +ae:=/dev/dsk/dos".
- (Which is held in the /etc/dosenv.def file, and you use the "dosopt"
- utility to view and change the settings in this file.)
- The "+amouse" causes the mouse to be used via the UNIX console driver,
- thus it automatically follows the current VT. Using "+adcom1" is not
- recommended for using the mouse. As long as /dev/dsk/dos is linked
- properly to the DOS partition device, then it will be automatically
- available. Unless these defaults have been changed by the user, the mouse
- and DOS partition should be automatically available without needing to
- use the command line parameters.

-
- It sounds like the permissions are wrong on /dev/dsk/dos. If they
- have the same major and minor numbers, then they connect to the same
- device. The actual name does not matter, but the permissions do.
