+----
+
+Like CP/M 3, ZPM3  exists in an experimental state and is started
+just like CP/M 3 above.  Just use the zpm_hd.img file to create
+your CF or SD Card.  There is an issue with the ZPMLDR app used
+to start ZPM.  Instead, just use CPMLDR which works exactly the
+same way.
+
+Note that ZPM3 seems to be completely constrainted to use drive
+A: as the boot drive.  So, the RomWBW adaptation of ZPM3 will
+"swap" the initial drive A: (typically RAM drive) with the
+ZPM3 boot drive at startup.

+This is a generic ZPM3 adaptation for RomWBW.
+
+To start ZPM3, first boot into CP/M 2.2 or ZSystem.  Then
+switch to the drive that contains the ZPM3 hard disk image
+and run CPMLDR.  You will be prompted for the disk unit
+of the ZPM3 image.
+
+You may notice that there is a ZPMLDR application on the
+hard disk image.  This application is equivalent to CPMLDR,
+but it has some issues with the number of drives that
+RomWBW supports.  So, as indicated above, use CPMLDR to
+launch ZPM3.
+
+I have not found a way to make ZPM3 start up with any drive
+other than A: as the system drive.  So, during the load
+process, the boot drive and drive A: are "swapped" so that
+the boot drive is always drive A:.  Use the ASSIGN
+command after starting ZPM3 to see how the drives get
+mapped.
+
+Per ZPM3 standard, files are distributed across different
+user areas depending on their usage.  Normal applications
+are in user 15.  Help files in user 10.  Configuration 
+files in user 14.
+
+In addition to the applications provided in the ZPM3
+distributio, the normal CP/M 3 files are included in user
+area 15.  A few typical ZCPR utility programs are also included
+in user area 15:
+
+ - ALIAS
+ - ARUNZ
+ - ERASE
+ - HELPC (named ZHELP)
+ - LBREXT
+ - SALIAS
+ - SETPATH
+ - VERRROR
+ - VLU
+ - ZCNFG
+ - ERASE (named ZERASE)
+ - ZEX
+ - ZFILER
+ - ZP
+ - SHOW (named ZSHOW)
+ - ZXD
+
+It is a bit confusing, but the ZPM3 system file is called CPM3.SYS.
+This is the ZPM3 default configuration and I guess it is done this
+way to maximize compatibility with CP/M 3.  You will notice that
+the startup banner will indicate ZPM3.
