-# Overview
-
-RomWBW software provides a complete, commercial quality implementation
-of CP/M (and workalike) operating systems and applications for modern
-Z80/180/280 retro-computing hardware systems. A wide variety of
-platforms are supported including those produced by these developer
-communities:
-
-- [RetroBrew Computers](https://www.retrobrewcomputers.org)
-  (<https://www.retrobrewcomputers.org>)
-- [RC2014](https://rc2014.co.uk) (<https://rc2014.co.uk>),  
-  [RC2014-Z80](https://groups.google.com/g/rc2014-z80)
-  (<https://groups.google.com/g/rc2014-z80>)
-- [Retro Computing](https://groups.google.com/g/retro-comp)
-  (<https://groups.google.com/g/retro-comp>)
-- [Small Computer Central](https://smallcomputercentral.com/)
-  (<https://smallcomputercentral.com/>)
-
-A complete list of the currently supported platforms is found in the
-\[Installation\] section.
-
-General features include:
-
-- Z80 Family CPUs including Z80, Z180, and Z280
-- Banked memory services for several banking designs
-- Disk drivers for RAM, ROM, Floppy, IDE ATA/ATAPI, CF, SD, USB, Zip,
-  Iomega
-- Serial drivers including UART (16550-like), ASCI, ACIA, SIO
-- Video drivers including TMS9918, SY6545, MOS8563, HD6445
-- Keyboard (PS/2) drivers via VT8242 or PPI interfaces
-- Real time clock drivers including DS1302, BQ4845
-- OSes: CP/M 2.2, ZSDOS, CP/M 3, NZ-COM, ZPM3, QPM, p-System, and
-  FreeRTOS
-- Built-in VT-100 terminal emulation support
-
-RomWBW is distributed as both source code and pre-built ROM and disk
-images. Some of the provided software can be launched directly from the
-ROM firmware itself:
-
-- System Monitor
-- Operating Systems (CP/M 2.2, ZSDOS)
-- ROM BASIC (Nascom BASIC and Tasty BASIC)
-- ROM Forth
-
-A dynamic disk drive letter assignment mechanism allows mapping
-operating system drive letters to any available disk media.
-Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.)
-support the use of multiple slices (up to 256 per device). Each slice
-contains a complete CP/M filesystem and can be mapped independently to
-any drive letter. This overcomes the inherent size limitations in legacy
-OSes and allows up to 2GB of accessible storage on a single device.
-
-The pre-built ROM firmware images are generally suitable for most users.
-However, it is also very easy to modify and build custom ROM images that
-fully tailor the firmware to your specific preferences. All tools
-required to build custom ROM firmware under Windows are included – no
-need to install assemblers, etc. The firmware can also be built using
-Linux or MacOS after confirming a few standard tools have been
-installed.
-
-Multiple disk images are provided in the distribution. Most disk images
-contain a complete, bootable, ready-to-run implementation of a specific
-operating system. A “combo” disk image contains multiple slices, each
-with a full operating system implementation. If you use this disk image,
-you can easily pick whichever operating system you want to boot without
-changing media.
-
-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.
-
-A tool is provided that allows you to access a FAT-12/16/32 filesystem.
-The FAT filesystem may be coresident on the same disk media as RomWBW
-slices or on stand-alone media. This makes exchanging files with modern
-OSes such as Windows, MacOS, and Linux very easy.
-
-# Acquiring RomWBW
-
-The [RomWBW Repository](https://github.com/wwarthen/RomWBW)
-(<https://github.com/wwarthen/RomWBW>) on GitHub is the official
-distribution location for all project source and documentation. The
-fully-built distribution releases are available on the [RomWBW Releases
-Page](https://github.com/wwarthen/RomWBW/releases)
-(<https://github.com/wwarthen/RomWBW/releases>) of the repository. On
-this page, you will normally see a Development Snapshot as well as
-recent stable releases. Unless you have a specific reason, I suggest you
-stick to the most recent stable release. Expand the “Assets” drop-down
-for the release you want to download, then select the asset named
-RomWBW-vX.X.X-Package.zip. The Package asset includes all pre-built ROM
-and Disk images as well as full source code. The other assets contain
-only source code and do not have the pre-built ROM or disk images.
-
-All source code and distributions are maintained on GitHub. Code
-contributions are very welcome.
-
-# Installation & Operation
-
-In general, installation of RomWBW on your platform is very simple. You
-just need to program your ROM with the correct ROM image from the RomWBW
-distribution. Subsequently, you can write disk images on your disk
-drives (IDE disk, CF Card, SD Card, etc.) which then provides even more
-functionality.
-
-Complete instructions for installation and operation of RomWBW are found
-in the [RomWBW User
-Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20User%20Guide.pdf).

-
--   Z80 Family CPUs including Z80, Z180, and Z280
--   Banked memory services for several banking designs
--   Disk drivers for RAM, ROM, Floppy, IDE ATA/ATAPI, CF, SD, USB, Zip,
-    Iomega
--   Serial drivers including UART (16550-like), ASCI, ACIA, SIO
--   Video drivers including TMS9918, SY6545, MOS8563, HD6445
--   Keyboard (PS/2) drivers via VT8242 or PPI interfaces
--   Real time clock drivers including DS1302, BQ4845
--   OSes: CP/M 2.2, ZSDOS, CP/M 3, NZ-COM, ZPM3, QPM, p-System, and
-    FreeRTOS
--   Built-in VT-100 terminal emulation support
-
-RomWBW is distributed as both source code and pre-built ROM and disk
-images. Some of the provided software can be launched directly from the
-ROM firmware itself:
-
--   System Monitor
--   Operating Systems (CP/M 2.2, ZSDOS)
--   ROM BASIC (Nascom BASIC and Tasty BASIC)
--   ROM Forth
-
-A dynamic disk drive letter assignment mechanism allows mapping
-operating system drive letters to any available disk media.
-Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.)
-support the use of multiple slices (up to 256 per device). Each slice
-contains a complete CP/M filesystem and can be mapped independently to
-any drive letter. This overcomes the inherent size limitations in legacy
-OSes and allows up to 2GB of accessible storage on a single device.
-
-The pre-built ROM firmware images are generally suitable for most users.
-However, it is also very easy to modify and build custom ROM images that
-fully tailor the firmware to your specific preferences. All tools
-required to build custom ROM firmware under Windows are included – no
-need to install assemblers, etc. The firmware can also be built using
-Linux or MacOS after confirming a few standard tools have been
-installed.
-
-Multiple disk images are provided in the distribution. Most disk images
-contain a complete, bootable, ready-to-run implementation of a specific
-operating system. A “combo” disk image contains multiple slices, each
-with a full operating system implementation. If you use this disk image,
-you can easily pick whichever operating system you want to boot without
-changing media.
-
-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.
-
-A tool is provided that allows you to access a FAT-12/16/32 filesystem.
-The FAT filesystem may be coresident on the same disk media as RomWBW
-slices or on stand-alone media. This makes exchanging files with modern
-OSes such as Windows, MacOS, and Linux very easy.

-ACQUIRING ROMWBW
-
-
-The RomWBW Repository (https://github.com/wwarthen/RomWBW) on GitHub is
-the official distribution location for all project source and
-documentation. The fully-built distribution releases are available on
-the RomWBW Releases Page (https://github.com/wwarthen/RomWBW/releases)
-of the repository. On this page, you will normally see a Development
-Snapshot as well as recent stable releases. Unless you have a specific
-reason, I suggest you stick to the most recent stable release. Expand
-the “Assets” drop-down for the release you want to download, then select
-the asset named RomWBW-vX.X.X-Package.zip. The Package asset includes
-all pre-built ROM and Disk images as well as full source code. The other
-assets contain only source code and do not have the pre-built ROM or
-disk images.
-
-All source code and distributions are maintained on GitHub. Code
-contributions are very welcome.
-
-
-
-INSTALLATION & OPERATION
-
-
-In general, installation of RomWBW on your platform is very simple. You
-just need to program your ROM with the correct ROM image from the RomWBW
-distribution. Subsequently, you can write disk images on your disk
-drives (IDE disk, CF Card, SD Card, etc.) which then provides even more
-functionality.
-
-Complete instructions for installation and operation of RomWBW are found
-in the RomWBW User Guide.

+OVERVIEW
+
+
+RomWBW software provides a complete, commercial quality implementation

 **`X`** - Exit the monitor program back to the main boot menu.
 
+## RomWBW System Configuration
+
+System Configuration (`SYSCONF`) is a utility that allows system configuration to 
+be set, dynamically and stored in NVRAM provided by an RTC chip.
+
+(`SYSCONF`) is both a ROM application ('W' Menu option), and a CP/M utility.
+Noting however the CP/M utility is not included on an disk image, it is found in
+the `Binary/Applications` folder of the RomWBW distribution.
+
+The $doc_user$ has additional information on the use of NVRAM to set your
+system configuration.
+
+### Basic Operation
+
+The application is an interactive application; it does not have a command line syntax.
+Instead commands are executed from within the application in a command line structure.
+
+When you first start the (`SYSCONF`) utility it will display the current switches
+followed by a command listing.
+
+When you first run the (`SYSCONF`) utility the NVRAM will be uninitialised, and can 
+be initialised using the (R)eset command, which writes default values to NVRAM.
+
+Updates are done immediately to NVRAM as you enter them, i.e. there is no confirm
+changes step. If you make any incorrect changes, you simply need to enter a new
+command to set the Switch value correctly.
+
+Once a change has been made it is available, however it may not take effect until
+the next system reboot. This is dependent on the Switch itself.
+
+If no NVRAM is provided by your hardware, then running this application will just
+report the missing hardware and exit immediately.
+
+To exit from the application use the (Q)uit command.
+
+### Commands and Syntax
+
+The following are the accepted commands, unless otherwise specified a "Space" 
+character is used to delimit parameters in the command.
+
+| Command    | Argument(s)      | Description                                   | 
+|------------|------------------|-----------------------------------------------| 
+| (P)rint    | -none-           | Display a list of the current switch value(s) | 
+| (S)et      | {SW} {val},...   | Sets an Switch {SW} with specific values(s)   | 
+| (R)eset    | -none-           | Reset all setting to default                  | 
+| (H)elp     | {SW}             | Provides help on the syntax (values)          | 
+| (Q)uit     | -none-           | Exit the application                          | 
+
+**Where**
+
+| Argument  | Description                                                          |
+|-----------|----------------------------------------------------------------------|
+| {SW}      | Switch ID, typically this is 2 character name to identify the switch |
+| {val},... | a "Comma" separated list of values to set into the switch            |
+
+### Switch Options
+
+#### Auto Boot (AB)
+
+This switch will define if the system will perform auto boot at the RomWBW boot prompt. 
+Enabling this will not prevent a user from typing a boot command, so long as the timeout is not
+exceeded. When configured this replaces the (`AUTO_CMD`) variable
+defined in build configuration.
+
+Making changes to auto boot has no affect until the next reboot.
+
+**Arguments**
+
+| Type     | Arguments  | Description                                            | 
+|----------|------------|--------------------------------------------------------| 
+| Enable   | 'E'        | Auto Boot. eg. "E,10" will auto boot, after 10 seconds | 
+|          | Timout     | Timeout in seconds in the range 0-15, 0 = immediate    | 
+| Disabled | 'D'        | No Auto Boot. e.g. "D" will disable autoboot           | 
+
+**Examples**
+
+| Command               | Description                                       | 
+|-----------------------|---------------------------------------------------| 
+| S AB E,10             | Enable Auto Boot with 10 second delay             | 
+| S AB D                | Disable Auto Boot                                 | 
+
+#### Boot Options (BO)
+
+This switch will define the boot command to be executed when auto boot is
+enabled.  When configured this replaces the (`AUTO_CMD`) variable
+defined in the ROM build configuration.
+
+Making changes to boot options has no affect until the next reboot.
+
+**Arguments**
+

+#### Usage (Bulk)
+
+The following describes how to assign drives in bulk without having to specify
+the identifiers of each drive being mapped. Instead bulk mode has a
+predefined set options (identified by single letter) which will map drives.
+Bulk mode works by assigning drives sequentially starting at A: until all
+drives are used, or there are no more options to process. Each option
+will typically map between 0 and N drives depending on the option
+and the available hardware in your system.
+
+`ASSIGN /B=`*`<option><option>`*... will perform bulk assignment .
+
+The following options will assign a small number of devices, typically you would
+place at beginning of an option list.
+
+| Option | Name     | Description                                 | Assigned |
+|--------|----------|---------------------------------------------|----------|
+| B      | Boot     | The boot device                             | 1        | 
+| A      | RAM      | Ram drive                                   | 0,1      |
+| O      | ROM      | Rom drive                                   | 0,1      |
+| F      | Floppy   | All floppy devices, with/without media      | 0,1,2,.. |
+| P      | Preserve | Skip and preserve the next drive assignment | 1        |
+| X      | Exclude  | Un-assign / Exclude the next drive          | 1        |
+
+A drive e.g. RAM, ROM, FLOPPY can only be assigned if it exists. if you system
+doesn't have the hardware that supports the device, then no devices will be
+assigned, and the next option will be processed.
+
+`B` assigns the boot device. If used the `B`oot drive should typically be
+assigned first.
+
+`P` will not make any changes to the next drive, it will skip over it. While the
+`X` option will un-assign the next drive, leaving a gap.
+
+The remaining options will fill drives mostly to end, from hard drive slices,
+generally choose 1 of the following:
+
+| Option | Name        | Description                                 | Assigned |
+|--------|-------------|---------------------------------------------|----------|
+| S      | Slices      | Assign slices from boot hard drive          | ...max   |
+| H      | Hard Drive  | Assign slices evenly from all hard drives   | ...max   |
+| L      | Legacy HD   | Assign slices from all hard drives (legacy) | 6,...max |
+| Z      | Exclude All | Un-assign all remaining drives               | ...max   |
+
+`S`lices assignment will map all remaining drives to slices from the boot device.
+If I have other hard drives present these will not be mapped by this option.
+
+e.g. `ASSIGN /B=BAOS`
+
+Will first assign drives `A:(Boot), B:(RAM), C:(ROM)` this leaves 13 drives
+which will be assigned to slices from the boot hard drive (D: thru P:),
+leaving no unused drives.
+
+'H'ard drive assignment will attempt to fill all remaining drive letters
+by splitting the number of drives remaining evenly across all.
+
+e.g. `ASSIGN /B=BAOH`
+
+Will first assign drives `A:(Boot), B:(RAM), C:(ROM)` this leaves 13 drives
+available. If I have 3 hard disks then (13/3) = 4 slices from each hard drive will
+be assigned to drives (D: thru O:), leaving a single unused drive (P:).
+
+`L`egacy hard drive assignment is identical to how the startup hard disk assignment
+works. ie. Attempt to assign up to 8 hard drives split across hard drives
+detected at boot.
+
+e.g. `ASSIGN /B=BAOL`
+
+Will first assign drives `A:(Boot), B:(RAM), C:(ROM)`. If I have 3 hard disks
+then (8/3) = 2 slices from each hard drive will be assigned to drives (D: thru I:),
+leaving 7 unused drives (J: thru P:).

+## Boot Recovery
+
+To assist users when driver faults or misconfiguration causes a boot 
+failure, RomWBW supports a limited recovery capability.  This is 
+achieved by allowing the user to reboot their machine, loading
+a minimal driver set.  Implementation of this feature requires a
+hardware input "BOOT RECOVERY" button to be available and 
+appropriate software configuration to be completed in the HBIOS.
+
+When implemented, holding the "BOOT RECOVERY" button in after a 
+reset or power cycle will cause the normal driver load process to
+be skipped in preference to a minimal set of drivers being loaded.
+
+Typically this would be: Serial communication, RAM disk and parallel
+port IDE interface drivers.
+
+Platforms supporting this option currently are the MBC, Duodyne and
+latter version of the SBC.
+ 
+# Configuration
+
+## RomWBW NVRAM Configuration
+
+On systems with RTC devices (that have Non-Volatile RAM), RomWBW supports storing
+some limited configuration option options inside this RAM.
+
+Several configuration options are currently supported; these are known as Switches.
+The following switch ID's are defined, and described in sections below.
+
+| Switch Number | Name         | Description                                   |      
+|---------------|--------------|-----------------------------------------------|

+| 0x02          | -n/a-        | -n/a- high order byte of previous switch      |      
+| 0x03          | Auto Boot    | Automatically boot enabled without user input |
+| 0x04 - 0xFE   | -future-     | Future general usage                          |
+| 0xFF          | Status Reset | Get Status or Reset Switches to Default       |     
+
+RomWBW uses bytes located at the start of RTC NVRAM, and includes a Parity check of
+the bytes in NVRAM to check for authenticity before using the configuration.
+
+| NVRAM Byte  | Name         | Description                       |

+| 0x04        | Parity Check | Checksum byte to check integrity  |

+The above data is copied into the HBIOS Configuration Block (HCB) at startup at 
+the location starting at CB_SWITCHES.

+### Setting NVRAM Options
+
+On systems with RTC devices (that have Non-Volatile RAM), RomWBW supports storing
+some limited configuration option options inside this NVRAM.
+
+Several configuration options are currently supported, these are known as Switches
+
+* Specify Automatic boot at startup, after an optional delay (AB)
+* Define the Disk or ROM App to be booted at for automatic boot (BO)
+
+RomWBW uses bytes located at the start of RTC NVRAM, and includes a checksum of 
+the bytes in NVRAM to check for integrity before using the configuration.
+
+Initially NVRAM has to be reset (with default values), before it can be used.
+As well as setting defaults, it also writes the correct checksum, and allows the
+NVRAM to be accessed and to store the RomWBW config.
+
+This is an explicit step that must be done, as any existing data stored is overwritten.
+If you are using NVRAM for other purposes, then you can continue to do so
+so long as you do NOT perform this Reset step.
+
+NVRAM may also need to be reset in these circumstances:
+
+* When there has been a loss of power to the NVRAM.
+* When upgrading to a new RomWBW version, or a RomWBW version that has new switches.
+* If the NVRAM has been overwritten by another application.
+
+If you want to continue to use NVRAM in your applications you may want to consider storing
+your data above the RomWBW Switch data.
+
+To configure these options an inbuilt ROM application is provided which can be accessed
+by the command "`W`" from the RomWBW boot menu.
+
+This application is also built as a CP/M utility, but is not included on an disk image, 
+it is found in the `Binary/Applications` folder of the RomWBW distribution.
+
+For further guidance on using this application please see the section 
+"RomWBW System Configuration" in the $doc_apps$ document.
+
+If your system has both a [Front Panel] as well as NVRAM, be aware that
+the Front Panel switches take precedence over the NVRAM configuration
+settings.
+
+Note that the WizNet class of Network devices also contain NVRAM which is
+entirely separate from the RomWBW configuration NVRAM described here.  A
+separate utility is used to set the WizNet NVRAM (see [CP/NET Client Setup]).

+#### Example 3 : Copy image using partition
+
+In the previous examples, the hard disk is addressed as a raw disk
+device and we took steps to calculate the assumed start of the RomWBW
+partition.  However, as long as the hd1k format is in use, it is
+also possible to just point `dd` directly to the partition itself.
+
+To do this, you must first determine the name that your operating
+system is using for the desired partition.  Frequently, partitions
+are named by simply adding a number after the name of the hard disk
+device.  For example, if the hard disk is /dev/sdg, the first
+partition is frequently /dev/sdg1 or /dev/sdgp1.
+
+Taking advantage of this, it is safer and easier to calculate the
+offset of a slice within the partition.  It is simply the slice
+number \* 8MB.  Example 2 above, could now be performed as:
