I started by copying all of the files from the distribution (contained in zsdos2.zip) into Support\ZSDOS.  From there I tested, modified, updated, and customized as documented below.  Finally, I cherry picked files that made sense to include on the ZSystem ROM disks.

 2. STAMPS.DAT has been replaced with an updated version.  The update was called STAMPS11.DAT and was found on the Walnut Creek CP/M CDROM.  The original version has a bug that prevents RSX (resident system extension) mode to load properly.

+==========================================================================
+              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.

+| --------------------|---|
+| ROM-based           |No |
+| Disk-based          |Yes|
+
+The purpose of this utility is to allow the copying of whole disk slices
+from one disk slice to another slice
+
+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.
+
+#### Syntax
+
+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.
+
+#### Usage
+
+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.
+
+#### Notes
+
+This tool has been tested on both SD and CF media types and with hd1k and hd512
+formatted media.
+
+You cannot copy slices between different hard disk formats (hd512 and
+hd1k) because the slices are incompatible.
+
+#### Etymology
+
+The `COPYSL` application was custom written for RomWBW and contributed
+by Mark Pruden.

+| ROM-based           |Yes|
+| Disk-based          |Yes|
+
+The `REBOOT` application is used to restart a running system from an
+operating system prompt.  It can invoke either a warm or cold restart
+via command line switches.
+
+#### Syntax
+
+| `REBOOT /W`
+| `REBOOT /C`
+| `REBOOT /?`
+
+- /C initiates a cold restart
+- /W initiates a warm restart
+- /? displays command line usage
+
+#### Usage
+
+Entering `REBOOT` with no parameters will display the usage and
+version information.  Use /C or /W to immediately initiate a 
+cold or warm restart.
+
+#### Notes
+
+A warm restart just returns to the Boot Loader menu.
+
+A cold restart will reinitialize the system as though power had
+been recycled.
+
+#### Etymology
+
+The `REBOOT` application was custom written for RomWBW by MartinR. All 
+of the hardware interface code is specific to RomWBW and the application
+will not operate correctly on non-RomWBW systems.
+
+The source code is provided in the RomWBW distribution.

+# Disk Layout
+
+RomWBW supports two hard disk layouts: the Classic layout used by 
+RomWBW with 512 directory entries per slice and a Modern layout with 
+1024 directory entries per slice.  These layouts are referred to as
+hd512 and hd1k respectively.
+
+WARNING: You **can not** mix the two hard disk layouts on one hard 
+disk device.  You can use different layouts on different hard disk 
+devices in a single system though.
+
+RomWBW determines which of the hard disk layouts to use for a given 
+hard disk device based on whether there is a RomWBW hard disk 
+partition on the disk containing the slices.   If there is no RomWBW 
+partition, then RomWBW will assume the 512 directory entry format for 
+all slices and will assume the slices start at the first sector of 
+the hard disk.  If there is a RomWBW partition on the hard disk 
+device, then RomWBW will assume the 1024 directory entry format for 
+all slices and will assume the slices are located in the defined 
+partition.
+
+RomWBW supports up to 256 CP/M slices (0-255).  Under hd512, the slices
+begin at the start of the hard disk.  Under hd1k, the slices reside
+within partition type 0x2E.
+
+RomWBW accesses all hard disks using Logical Block Addressing (pure
+sector offset).  When necessary, RomWBW simulates the following disk
+geometry for operating systems:
+
+- Sector = 512 Bytes
+- Track = 16 Sectors (8KB per Track)
+- Cylinder = 16 Tracks (256 Sectors per Cylinder, 128KB per Cylinder)
+
+If one is used, the FAT Partition must not overlap the CP/M slices.
+The FAT partition does not need to start immediately after the CP/M
+slices nor does it need to extend to the end of the hard disk.  Its
+location and size are entirely determined by its corresponding
+partition table entry.
+
+Drive letters in CP/M are ASSIGNed to the numbered slices as desired.  
+At boot, RomWBW automatically assigns up to  8 slices to drive letters 
+starting with the first available drive letter (typically C:).
+
+Microsoft Windows will assign a single drive letter to the FAT partition
+when the CF/SD Card is inserted.  The drive letter assigned has no 
+relationship to the CP/M drive letters assigned to CP/M slices.
+
+In general, Windows, MacOS, or Linux know nothing about the CP/M slices 
+and CP/M knows nothing about the FAT partition.  However, the FAT 
+application can be run under CP/M to access the FAT partition 
+programmatically.
+
+A CP/M slice is (re)initialized using the CP/M command CLRDIR.  A CP/M 
+slice can be made bootable by copying system image to the System Area 
+using SYSCOPY.
+
+The FAT partition can be created from CP/M using the FDISK80 application.
+
+The FAT partition can be initialized using the FAT application from CP/M
+using the command `FAT FORMAT n:` where n is the RomWBW disk unit 
+number containing the FAT partition to be formatted.
+
+## Modern Disk Layout (hd1k)
+
+![Modern Disk Layout](Graphics/hd1k)
+
+The CP/M filesystem on a Modern disk will accommodate 1,024 directory 
+entries.
+
+The CP/M slices reside entirely within a hard disk partition of type
+0x2E.  The number of slices is determined by the number of slices that
+fit within the partition spaces allocated up to the maximum of 256.
+
+## Classic Disk Layout (hd512)
+
+![Classic Disk Layout](Graphics/hd512)
+
+The CP/M filesystem on a Classic disk will accommodate 512 directory 
+entries.
+
+The CP/M slices reside on the hard disk starting at the first sector
+of the hard disk.  The number of CP/M slices is not explicitly recorded
+anywhere on the hard disk.  It is up to the system user to know how
+many slices are being used based on the size of the hard disk media
+and/or the start of a FAT partition.
+
+A partition table may exist within the first sector of the first
+slice.  For Classic disks, the partition table defines only the
+location and size of the FAT partition.  The Partition Table does
+not control the location or number of CP/M slices in any way.
+
+The Partition Table resides in a sector that is shared with the System 
+Area of CP/M Slice 0.  However, the RomWBW implementation of CP/M takes 
+steps to avoid changing or corrupting the Partition Table area.
+
+The FAT partition can be created from CP/M using the FDISK80 
+application.  The user is responsible for ensuring that the start of the
+FAT partition does not overlap with the area they intend to use for 
+CP/M slices.  FDISK80 has a Reserve option to assist with this.
+
+## Mapping to Media ID
+
+HBIOS has a definition of "Media ID", which defines the type and physical
+properties of disk media provided by an underlying storage device. For a 
+complete list of Media ID's please see the following section
+
+[Disk Input/Output (DIO)]
+
+There are two important Media ID's relating to Hard Disk Layouts:
+
+| **Media**  | **ID** | **Format / Meaning**                                        |
+|------------|-------:|-------------------------------------------------------------|
+| MID_HD     |      4 | Classic Disk Layout (hd512) *--and--* HBIOS Hard Disk Drive |
+| MID_HDNEW  |     10 | Modern Disk Layout (hd1k)                                   |
+
+HBIOS typically does not understand the format of data on a device,
+instead just treating all hard disks as raw sectors. `MID_HD` is the typical
+Media ID used by HBIOS to describe high capaity hard disk media
+
+When the Modern Disk Layout was added, the `MID_HDNEW`, was added to
+differentiate (at the oerating system level) between the Classic and Modern layouts.
+
+However HBIOS itself typically does NOT make this distinction, since the use 
+of these two formats is determined by the operating system based on the 
+partition table on the media. 
+There are two important HBIOS functions that deal with Media ID.
+
+* [Function 0x18 -- Disk Media (DIOMEDIA)]
+
+* [Function 0xE0 -- Calculate Slice (EXTSLICE)]

-; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE
-; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY.  THIS FILE CONTAINS
-; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS.  IT IS INTENDED THAT YOU MAKE
-; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS.
-; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY
-; YOUR FILE IN THE BUILD PROCESS.
+; THIS FILE DEFINES THE DEFAULT CONFIGURATION SETTINGS FOR THE PLATFORM
+; INDICATED ABOVE.  THESE SETTINGS DEFINE THE OFFICIAL BUILD FOR THIS
+; PLATFORM AS DISTRIBUTED IN ROMWBW RELEASES.
 ;
-; THE SETTINGS BELOW ARE THE SETTINGS THAT ARE MOST COMMONLY MODIFIED FOR THIS PLATFORM.
-; MANY OF THEM ARE EQUAL TO THE SETTINGS IN THE INCLUDED FILE, SO THEY DON'T REALLY DO
-; ANYTHING AS IS.  THEY ARE LISTED HERE TO MAKE IT EASY FOR YOU TO ADJUST THE MOST COMMON
-; SETTINGS.
+; ROMWBW USES CASCADING CONFIGURATION FILES AS INDICATED BELOW:
 ;
-; N.B., SINCE THE SETTINGS BELOW ARE REDEFINING VALUES ALREADY SET IN THE INCLUDED FILE,
-; TASM INSISTS THAT YOU USE THE .SET OPERATOR AND NOT THE .EQU OPERATOR BELOW. ATTEMPTING
-; TO REDEFINE A VALUE WITH .EQU BELOW WILL CAUSE TASM ERRORS!
