 ## Coding Style
 
-Due to the nature of the project, you will find a variety of coding styles.  When making changes to existing code, please try to be consistent with the existing coding style.  You may not like the current style, but no one likes mixed styles
-in one file/module.

+styles.  When making changes to existing code, please try to be
+consistent with the existing coding style.  You may not like the current
+style, but no one likes mixed styles in one file/module.
 
-Be careful with white space.  RomWBW is primarily assembly langauge code.  The use of tab stops at every 8 characters is pretty standard for assembler.  If you use something else, then your code will look odd when viewed by others.

-In most cases, the use of `<cr><lf>` line endings is preferred.  This is standard for the operating systems of the era that RomWBW provides.  Also note that CP/M text files should end with a ctrl-Z (0x1A).  This is not magically added by the
-tools that generate the disk images.

+
+## Hints for Developers
+
+- The majority of RomWBW is assembled with TASM (and it's compatible
+  equivalent sz80as).  These tools have quirks that are very subtle.  For
+  example, TASM does not evaluate expressions in the standard way.  It
+  uses a left to right approach.  Check the TASM documentation carefully.
+
+- The following two Z80 instructions highlight a common issue with the
+  Z80 assembler syntax.  Parens in operands frequently indicate an
+  indirect reference.  To treat the operand as an expression, use the
+  second format.
+
+```
+	LD	A,(5+5)		; Load A with the value at address 10
+	LD	A,0+(5+5)	; Load A with the value 10
+```
+
+- The RomWBW documewntation in the Doc directory is generated with a
+  process outside of the normal build process.  To update documentation,
+  please update the .md files in Source/Doc.  Those are the Markdown
+  source files for the documentation.  The PDF files will be updated
+  offline from those.

+; 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.
+;______________________________________________________________________________

+#### Compressed ROM Image File: RCZ80_ez512_std_64k.rom
+
+The RomWBW utility program 'compress' is designed to squeeze the 
+compiled RomWBW 128K file 'RCZ80_ez512_std.upd' into a 64K ROM. As there
+are many areas in RomWBW with repeating bytes of the same value, it is 
+possible to compress the 128K file to fit into a 64K ROM.
+
+The compression program looks for two or more consecutive bytes of the 
+same value (any values of $00 to $FF). If it finds duplicates, it leaves
+two of the duplicate bytes followed by a byte count, n-1 (n <= $FF), 
+where n is the total number of duplicates. If the program succeeds in 
+compressing the input file to fit into the available space, the file 
+'RCZ80_ez512_std_64k.rom' is constructed, along with a short Z80 
+decompression program that will be stored in the last 256 bytes of the 
+ROM. The constructed 64K file is saved and the unused storage space is 
+output in bytes. Should compression fail to fit the input file into 
+available space, only an error message and the overrun in bytes is 
+output.
+
+The decompression program, located at $FF00, is executed at startup via 
+the 3-byte jump at location $0000, decompressing the stored code in ROM 
+into the computer's RAM. When decompression finishes, control is passed 
+to RAM location $0000, which in turn starts execution of RomWBW.
+
+The 64K ROM Layout:
+
+* The first 3 bytes are always $C3 $00 $FF, a jump to the Z80 
+  decompression code located at $FF00 in the ROM.
+
+* Locations $0003 up to, and including, $FEFF are available to store 
+  the compressed 128K input file.
+
+* Location $FF00 up to, and including, $FFFF, is where the Z80 
+  decompression program is stored.

-## Disk Operations/Commands
-
-With some understanding of how RomWBW presents disk space to the
-operating systems, we need to go over the options for actually setting
-up your disk(s) with content.
-
-### Preparing Media for First Use
-
-You can initialize the media in-place using your RomWBW system.
-Essentially, this means you are creating a set of blank directories on
-your disk so that files can be saved there.
-This is somewhat analogous to partitioning of a hard disk
-or doing a low level format of a floppy disk.
-
-Initilizing a Floppy disk is covered in the section [Floppy Disk Formatting],
-or for a Hard disk the section [Hard Disk Preparation] covers the steps to 
-manually setup a hard disk for first use. 
-
-### Clearing (Formatting) Drives 
-
-This is somewhat analogous to doing a FORMAT operation on other systems.
-
-With RomWBW you use the `CLRDIR` command to do this.
-This command is merely "clearing out" the directory space of the drive
-referred to by a drive letter and setting up the new empty directory.
-
-Refer to $doc_apps$ for more information on use of the `CLRDIR` command.
-
-Since `CLRDIR` works on drive letters, make
-absolutely sure you know what media and slice are assigned to that
-drive letter before using `CLRDIR` because `CLRDIR` will wipe out any
-pre-existing contents of the slice.
-
-After `CLRDIR` completes, the slice should be ready to use by the operating
-system via the drive letter assigned.
-Start by using the `DIR` command on the drive.
-This should return without error, but list no files.
-
-Here is an example of using `CLRDIR`.  In this example, the `ASSIGN`
-command is used to show the current drive letter assignments.  Then
-the `CLRDIR` command is used to initialize the directory of drive 'G'
-which is slice 2 of hard disk device IDE0 ("IDE0:2").

+; 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.
+;
+; ROMWBW USES CASCADING CONFIGURATION FILES AS INDICATED BELOW:
+;
+; cfg_MASTER.asm			- MASTER: CONFIGURATION FILE DEFINES ALL POSSIBLE ROMWBW SETTINGS
+; |
+; +-> cfg_<platform>.asm		- PLATFORM: DEFAULT SETTINGS FOR SPECIFIC PLATFORM

+;         +-> Config/<plt>_<cust>.asm	- USER: CUSTOM USER BUILD SETTINGS
+;
+; THE TOP (MASTER CONFIGURATION) FILE DEFINES ALL POSSIBLE ROMWBW
+; CONFIGURATION SETTINGS. EACH FILE BELOW THE MASTER CONFIGURATION FILE
+; INHERITS THE CUMULATIVE SETTINGS OF THE FILES ABOVE IT AND MAY
+; OVERRIDE THESE SETTINGS AS DESIRED.
+;
+; OTHER THAN THE TOP MASTER FILE, EACH FILE MUST "#INCLUDE" ITS PARENT
+; FILE (SEE #INCLUDE STATEMENT BELOW).  THE TOP TWO FILES SHOULD NOT BE
+; MODIFIED.
+;
+; TO CUSTOMIZE YOUR BUILD SETTINGS YOU SHOULD MODIFY THIS FILE, THE
+; DEFAULT BUILD SETTINGS (Config/<platform>_std.asm) OR PREFERABLY
+; CREATE AN OPTIONAL CUSTOM USER SETTINGS FILE THAT INCLUDES THE DEFAULT
+; BUILD SETTINGS FILE (SEE EXAMPLE Config/SBC_user.asm).
+;
+; BY CREATING A CUSTOM USER SETTINGS FILE, YOU ARE LESS LIKELY TO BE
+; IMPACTED BY FUTURE CHANGES BECAUSE YOU WILL BE INHERITING MOST
+; OF YOUR SETTINGS WHICH WILL BE UPDATED BY AUTHORS AS ROMWBW EVOLVES.
+;
+; PLEASE REFER TO THE CUSTOM BUILD INSTRUCTIONS (README.TXT) IN THE
+; SOURCE DIRECTORY (TWO DIRECTORIES ABOVE THIS ONE).
+;
+; *** WARNING: ASIDE FROM THE MASTER CONFIGURATION FILE, YOU MUST USE
+; ".SET" TO OVERRIDE SETTINGS.  THE ASSEMBLER WILL ERROR IF YOU ATTEMPT
+; TO USE ".EQU" BECAUSE IT WON'T LET YOU REDEFINE A SETTING WITH ".EQU".
