 **`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                                   |      
+|---------------|--------------|-----------------------------------------------|

+| 0x01          | Boot Options | ROM or Disk Boot Settings                     |      
+| 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                       |      
+|-------------|--------------|-----------------------------------|

+| 0x01 - 0x03 | Switch Data  | Actual Switch Data                |      
+| 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.
+
+### Boot Options (NVSW_BOOTOPTS) 
+
+16 bit Switch defining the ROM application or Disk device to boot if
+automatic booting is enabled.

+
+| Bits 7-6 | Bit 5                  | Bit 4    | Bits 3-0                             |

+| -unused- | 0 = Auto Boot Disabled | -unused- | -undefined-                          |     
+
+### Status Reset (0xFF)
+
+The Status Reset switch is not a general purpose switch, it is a control mechanism
+to allow the global status of all switches to be determined. The meaning of the switch
+is different for Read (Get Status) and Write (Reset NVRAM)
+
+#### GET (Get Status)
+
+The read Get Status of switches. This returns very specific values from the function call.
+
+| Status                                       | A Register | Z / NZ Flag  |
+|----------------------------------------------|------------|--------------|
+| NVRAM does not exist                         | A=0        | NZ flag set  |
+| NVRAM exists, but has not been initialised   | A=1        | NZ flag set  |
+| NVRAM exists, and has been fully initialised | A='W'      | Z flag set   |
+
+#### SET (Reset NVRAM)
+
+Reset NVRAM to default values. This will wipe any existing data and set default
+values into NVRAM.

-### Changing Console and Console speed
+### 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]).

+In the previous examples, the hard disk is addressed as a raw disk

+also possible to just point `dd` directly to the partition itself.

+To do this, you must first determine the name that your operating

+; 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

+;
+; 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

+; 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
