FIX for DMDRVR.BIN, or others


        There are some block device drivers which do not set the "units" byte 
in the device header.  This is not necessary for DOS or for the driver itself 
but it is necessary for The $25 Network.  Fortunately this byte should always
be unused so it is possible to alter it in the program code on disk.  This byte 
is not changed by DOS as the Technical manual says.  DOS does alter this byte 
in its own internal device drivers but not in external user device drivers.

        FIX.BAS is a BASICA/GWBASIC program which will fix your device driver.
The only driver known to need this fixup is DMDRVR.BIN which is shipped with 
some large Seagate hard disk drives.  You will know your driver needs this 
fixup if  The $25 Network cannot use or skips over the drives which the device 
driver in question supports.  Type:

                GWBASIC FIX

You will be asked for the name of the driver to be fixed, then if it exists in 
the specified path you will be asked how many drives (ie, letters) the device 
driver is supporting.  For DMDRVR.BIN this number is the number of added 
partitions on the physical disk since DOS handles the first partition normally.
If the driver is not a character device driver the "units" byte is modified on 
the disk.  Reboot to test.
