Release Testing WIP

The STARTZPM and STARTZCM startup alias files include commands to set the ZCPR path with "$$" as one of the parameters.  The '$' characters were not escaped.

Thanks and credit to Joao Miguel Duraes for identifying this issue and Wayne Hortensius for the solution.

+This file contains information useful to those upgrading to a new
+release of RomWBW.
+
+All Versions
+============
+
+- Please review the "Upgrading" Section of the RomWBW User Guide.
+
+- Many RomWBW-specific applications are locked to the ROM version
+  being used.  After upgrading your ROM, you will need to upgrade
+  your disk-based RomWBW applications and OS boot files.
+
+Version 3.5
+===========
+
+- RomWBW is now more strict with respect to hard disk partition
+  tables.  If your hard disk media was created using any of the
+  pre-built disk image files, this will **not** affect you.  Otherwise,
+  you may find you are unable to access slices beyond the first
+  slice.  If so, use FDISK80 to reset the partition table on the
+  disk.  This will restore normal access to all slices.  **Only** do
+  this if you are having an issue.
+
+- For those building custom ROMs that are overriding `DEFSERCFG`, note 
+  that this setting has been moved to a `#DEFINE` instead of an equate 
+  (`.SET` or `.EQU`).  You will find this `#DEFINE` at the top of all
+  standard config files.  You will need to change your setting to a
+  `#DEFINE` at the top of your config file and remove any `.SET` or
+  `.EQU` lines for `DEFSERCFG`.
+
+- Combining config settings `AUTOCON` and `VDAEMU_SERKBD` causes issues
+  at the boot loader prompt.  So, all config files have been changed to
+  consistently enable `AUTOCON` and disable `VDAEMU_SERKBD` (`$FF`).  If
+  are want to use `VDAEMU_SERKBD`, you need to set it in your config
+  file as well as disabling AUTOCON.

+
+## Primary Features
+
+By design, RomWBW isolates all of the hardware specific functions in the
+ROM chip itself. The ROM provides a hardware abstraction layer such that
+all of the operating systems and applications on a disk will run on any
+RomWBW-based system. To put it simply, you can take a disk (or CF/SD/USB
+Card) and move it between systems transparently.

+Supported hardware features of RomWBW include:

+listed below. Please contact the author if there are any other such
+projects that are not listed.
+
+Z88DK
+
+Z88DK is a software powerful development kit for Z80 computers
+supporting both C and assembly language. This kit now provides specific
+library support for RomWBW HBIOS. The Z88DK project is hosted at
+https://github.com/z88dk/z88dk.
+
+Paleo Editor
+
+Steve Garcia has created a Windows-hosted IDE that is tailored to
+development of RomWBW. The project can be found at
+https://github.com/alloidian/PaleoEditor.
+
+Z80 fig-FORTH
+
+Dimitri Theulings’ implementation of fig-FORTH for the Z80 has a
+RomWBW-specific variant. The project is hosted at
+https://github.com/dimitrit/figforth.
+
+Assembly Language Programming for the RC2014 Zed
+
+Bruce Hall has written a very nice document that describes how to
+develop assembly language applications on RomWBW. It begins with the
+setup and configuration of a new RC2014 Zed system running RomWBW. It
+describes not only generic CP/M application development, but also RomWBW
+HBIOS programming and bare metal programming. The latest copy of this
+document is hosted at http://w8bh.net/Assembly for RC2014Z.pdf.

+==========================================================================
+              CopySlice Utility v0.2 for RomWbW computers
+                   written by Mark Pruden (Sept 2024)
+==========================================================================
+
+Purpose:
+--------
+
+The purpose of this utility is to allow the copying of whole disk slices
+from one disk slice to another slice
+
+Background
+----------
+
+This tool is only supported by RomWBW HBIOS, it uses HDIOS for all its 
+disk IO. UNA UBIOS is not supported by this tool. 
+
+This tool is running on CP/M 2.2 or 3.0 and has access to full 64kb of
+RAM, with a minimum of 48kb TPA
+
+This tool only works with hard disk devices, other media types like 
+floppy, are not supported at this time. This tool works across different 
+hard disk device types, even of different physical type
+
+Both hd1k and hd512 are fully supported, however copying from one layout 
+type to the other is not supported.
+
+During operation data is copied in a single read/write pass, data is not 
+verified by default. If there is a write error, it will be reported, and
+operation will stop.
+
+General Usage
+-------------
+This tool operates at the disk level via RomWBW, thus all disk identifiers 
+are in the RomWBW <disk>.<unit> format
+
+The syntax (similar to copy) for the command is:
+
+  COPYSL <destunit>[.<slice>]=<srcunit>[.<slice>] [/options]
+  
+E.g.
+  
+  COPYSL 3.3=2.10 /U
+
+Means copy from slice 10 on disk 2, onto disk 3 slice 3. This is in 
+unattended mode, so you will not be asked to confirm the copy operation.
+
+Options
+-------
+F - Full disk copy. Copies the complete disk slice, all sectors.
+U - Unattended. Will complete copy without confirmation from the user.
+V - Verify. Does an additional read and verify after write.
+
+Description
+-----------
+
+When run COPYSL will perform command line argument validation and display 
+an error if they are illegal. Also any disk IO errors will cause COPYSL
+to exit.
+
+When specifying slice number(s) a check is made that the slice number is 
+valid, i.e. not too large that it would extend past the end of the 
+partition (hd1k), or the end of the media (hd512). For hd512 a check is
+also performed to ensure that the slice would not extend into the first 
+defined partition.
+
+The copy operation will be faster if the source disk has been formatted
+with the CP/M file system, since during copy the CP/M directory is scanned, 
+and unused blocks are not copied. 
+
+If a filesystem is not found, (or the /F option is chosen) all data is 
+copied.
+
+Verification (if option chosen) will do an aditional read (after write)
+and compare the data read matches what was written. This compare is only
+on every 32'nd byte. This is done for efficiency. 
+
+During copy dots "." will be displayed to indicate progress of the copy.
+Each "." represents 16 kBytes of data. Each line of "." 's is 1 mBytes.
+
+Testing
+-------
+This tool has been writen and tested on a SC126 computer. Testing been on both 
+SD and CF media types, and with both hd1k and hd512 formats
+
+History
+-------
+* v 0.1 Initial Release
+* v 0.2 Added the /v command option to read and verify after write
+
+Future
+------
+* support ability to read and write from image files stored in CP/M filesystem
+* maybe the verify options could allow more complete verification.
+  This would be at the cost of performance
+* ability to abort once the copy has started <ctrl><c>
+
+

+; REBOOT - Allows the user to Cold or Warm Boot the RomWBW System
+; Version 1.0 12-October-2024
+;==============================================================================
+;
+; Author: MartinR (October 2024)
+;    Based **very heavily** on code by Wayne Warthen (wwarthen@gmail.com)
+;______________________________________________________________________________
+;
+; Usage:
+;   REBOOT [/C] [/W] [/?]
+;     ex: REBOOT	Display version and usage
+;         REBOOT /?	Display version and usage
+;         REBOOT /C	Cold boot RomWBW system
+;	  REBOOT /W	Warm boot RomWBW system
+;
+; Operation:
+;   Cold or warm boots a RomWBW system depending on the user option selected.
+;
+; This code will only execute on a Z80 CPU (or derivitive)
+;
+; This source code assembles with TASM V3.2 under Windows-11 using the
+; following command line:
+;	tasm -80 -g3 -l REBOOT.ASM REBOOT.COM
+;	ie: Z80 CPU; output format 'binary' named .COM (rather than .OBJ)
+;	and includes a symbol table as part of the listing file.
+;______________________________________________________________________________
+;
+; Change Log:
+;   2024-09-11 [WBW] Release of RomWBW CPU Speed Selector v1.0 used as the basis
+;   2024-10-12 [MR ] Initial release of version 1.0
