-## 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                                   |

-### 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.

-Partial writes can be completed with 39SF040 chips. Other chips require entire flash to be erased before being written.
-An SBC V2-005 MegaFlash or Z80 MBC required for 1mb flash support. The Updater assumes both chips are same type
-Failure handling has not been tested.
-Timing broadly calibrated on a Z80 SBC-v2

+| --------------------|---|
+| ROM-based           |Yes|
+| Disk-based          |Yes|
+
+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 utility ('W' Menu option), and a CP/M application.
+Noting however the CP/M application is not included on an disk image, it is found in
+the `Binary/Applications` folder of the RomWBW distribution.
+
+The section "Setting NVRAM Options" in the $doc_user$ has additional information 
+on the use of NVRAM to set your system configuration.
+
+#### Syntax
+
+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.
+`SYSCONF` command takes no arguments.
+
+| `SYSCONF`
+
+#### Usage
+
+When you first start the (`SYSCONF`) utility it will display the current switches
+followed by a command listing. e.g.
+
+```
+RomWBW System Config Utility
+
+Current Configuration: 
+  [BO] / Boot Options: ROM (App = "H")
+  [AB] / Auto Boot: Disabled
+
+Commands:
+  (P)rint - Display Current settings
+  (S)et {SW} {val}[,{val}[,{val}]]- Set a switch value(s)
+  (R)eset - Init NVRAM to Defaults
+  (H)elp [{SW}] - This help menu, or help on a switch
+  e(X)it - Exit Configuration
+  
+$
+```
+
+When you run (`SYSCONF`) for the first time 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)          |
+| e(X)it    | -none-           | Exit the application                          |

+| {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.
+

+| 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           |

+Full game documentation can be found here <https://infodoc.plover.net/>
+
+The game files are a virtual machine code commonly known as Z-Machine, they
+are portable and will run on any machine that has a Z-Machine interpreter.
+
+* All the Z3 games come with the official CP/M interpreter (the `COM` file) 
+  version C last updated by Inforcom on 5th Feb 1985. You can simply run the
+  game by running it from the `COM` program  
+* All latter games Z4, Z5,.. and above, (Marked as * in the listing above)
+  are more sophisticated and require a better interpreter. i.e. VEZZA. 
+
+#### VEZZA (User Area 15)
+
+Vezza is a modern Infocom/Inform/Z-machine text adventure interpreter for 8 bit
+z80 based computers.  What makes it modern is that it is written in hand-crafted
+z80 assembler for maximum speed, and can load not only the classics such as
+Zork 1,2 and 3 but also the later games.
+
+It can run Z1 up to Z8 inform format interactive fiction game files. To run 
+a game with Vezza just type Vezza followed by the game you want to run. e.g.
+
+`VEZZA ZORK0.Z6`
+
+**Note:** One of the bigger constraints is available RAM. An OS such as ZPM
+since it uses banked RAM does have a good amount of available RAM and was 
+used to test these games work.

-## 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").
-
-```
-B>ASSIGN

-   A:=MD0:0
-   B:=MD1:0

-### Checking Disk Layout
-
-If you are not sure which disk layout is used for your existing
-media, you can use the CP/M 2.2 `STAT` command to display information
-including the number of "32  Byte Directory Entries"
-for a drive letter on the corresponding hard disk.  
-
-- If it indicates 512, your disk layout is legacy (hd512).

-#### Adding Slices to Combo Image
+There are two approaches you can use to create custom hard disk
+images with multiple slices.
+
+- You can add/modify a configuration file and run the RomWBW
+  build process.  This requires running the RomWBW build process, but
+  will cause your custom hard disk images to be created with every

+  or `cat` (Linux/MacOS).  This does not require running the RomWBW
+  build process, but will require manually recreating your custom
+  hard disk images when you upgrade to new releases of RomWBW.
+
+The following sections provide more detail on each approach.
+
+#### Building Custom Hard Disk Images
+
+The RomWBW build process builds the disk images defined in the
+`Source/Images` directory.  The resultant images are placed in the `Binary`
+directory and are ready to copy to your media.
+
+These aggregate disk images are defined using .def files.  You will see there
+is a combo.def file in the Images directory that defines the slices for the
+Combo disk image.  You can create your own .def files as desired to
+automatically create custom aggregate disk images.  When the RomWBW
+build process is run, it will automatically look for all .def files
+in the `Source/Images` directory and create aggregate disk images for
+each using the same base name as the .def file.
+
+There is an example of this in the `Images` directory called 
+`all.def.example`.  You can remove the ".example" suffix so that the 
+file is called `all.def`.  Now, if you run the RomWBW build process, it 
+will automatically generate `hd512_all.img` and `hd1k_all.img` files in 
+the `/Binary` directory. This example creates an aggregate disk image 
+with all of the possible slices.
+
+You could also modify the contents of the Combo disk image by simply
+modifying the `combo.def` configuration file.  However, it is recommended
+that you leave the Combo image alone and simply define your own.
+
+NOTE: All of the `hd1k_xxx.img` aggregate disk image files created in
+this way (including the Combo disk image) will already be prefixed with 
+`hd1k_prefix.dat`, so you do not need to add the prefix file.  They are 
+ready to write to your media.

+# Native CH376 Driver
+
+The native CH376 HBIOS driver is written in c, using z88dk's zcc compiler.
+
+The build process, is a 3 stage process.
+
+1. Compile all the C code to assembly files (.asm)
+2. Translate the produced .asm files syntax to compile with the RomWBW assembler (.s)
+3. Assemble the driver .s files as per the standard HBIOS build process
+
+The original C code and produced/translated .s files are all committed units in the repo. But it is
+expected, that only the c files are to be modified/updated.  
+
+The .s files are checked in, so builders do not require the C compiler tool chain (z88dk) to be installed.
+
+The c compiling/translating process is only supported on linux, as the script to translate the .asm files
+to .s files is a linux bash script.  (Although the script can be easily run within Windows's Sub-system for linux)
+
+## Compiling the C code
+
+> Requires linux with docker installed.
+
+> The C code only needs to be recompiled if and when you change any of the `.c` source files.
+
+To compile the `.c` code to generate updated `.s` files:
+
+Within the `Source/HBIOS/ch376-native` directory:
+
+```
+make
+```
+
+The make script will search for z88dk's `zcc` compiler, if not found, will attempt to use a docker wrapper.
+It will not work if z88dk or docker is not installed.
+
+## USB Native Driver systems
+
+The default builds of RomWBW do not enable the CH376 native usb drivers.  These drivers take a reasonable chunk of ROM space.  As such you
+will need to build a new HBIOS image customised for your platform.  Please familiarise yourself with the HBIOS/RomWBW build and configuration process.
+
+The usb driver is divided into a few sub-system, which can be individually enabled within the standard HBIOS config files.
+
+For activating the full native USB support, the non native CH365 drivers need to be disabled and the relevant `CHNATIVE` drivers enabled
+
+Example:
+
+```
+CHENABLE       .SET    FALSE    ; CH: ENABLE CH375/376 USB SUPPORT
+CH0USBENABLE   .SET    FALSE    ; CH375: ENABLE CH375 USB DRIVER
+CH1USBENABLE   .SET    FALSE    ; CH376: ENABLE CH376 USB DRIVER
+CHNATIVEENABLE .SET    TRUE     ; CH376: ENABLE CH376 NATIVE USB DRIVER
+CHSCSIENABLE   .SET    TRUE     ; CH376: ENABLE CH376 NATIVE MASS STORAGE DEVICES (REQUIRES CHNATIVEENABLE)
+CHUFIENABLE    .SET    TRUE     ; CH376: ENABLE CH376 NATIVE UFI FLOPPY DISK DEVICES (REQUIRES CHNATIVEENABLE)
+CHNATIVEEZ80   .SET    FALSE    ; CH376: DELEGATE USB DRIVERS TO EZ80'S FIRMWARE
+CHNATIVEFORCE  .SET    TRUE     ; CH376: DISABLE AUTO-DETECTION OF MODULE - ASSUME ITS INSTALLED
+```
+
+As the USB driver is a fairly large, you may need to disable other HBIOS drivers in your configuration.  As such, it is
+recommend to only enable drivers for your platform's hardware configuration - for example, enable only the serial driver
+required for your system.
+
+```
+DUARTENABLE   .SET    FALSE     ; DUART: ENABLE 2681/2692 SERIAL DRIVER (DUART.ASM)
+UARTENABLE    .SET    FALSE     ; UART: ENABLE 8250/16550-LIKE SERIAL DRIVER (UART.ASM)
+ACIAENABLE    .SET    FALSE     ; ACIA: ENABLE MOTOROLA 6850 ACIA DRIVER (ACIA.ASM)
+SIOENABLE     .SET    TRUE      ; SIO: ENABLE ZILOG SIO SERIAL DRIVER (SIO.ASM)
+```
+
+You may also need to disable other storage drivers:
+
+```
+FDENABLE      .SET    FALSE     ; FD: ENABLE FLOPPY DISK DRIVER (FD.ASM)
+IDEENABLE     .SET    FALSE     ; IDE: ENABLE IDE DISK DRIVER (IDE.ASM)
+PPIDEENABLE   .SET    FALSE     ; PPIDE: ENABLE PARALLEL PORT IDE DISK DRIVER (PPIDE.ASM)
+```
+
+### base-drv `CHNATIVEENABLE`
+
+The `base-drv` system contains the core code to discover, enumerate, and communicate with USB devices.
+
+It also includes the driver code to enumerate and operating USB devices through a USB hub.
+
+### scsi-drv `CHSCSIENABLE`
+
+The `scsi-drv` system can be enabled with the HBIOS config `CHSCSIENABLE`
+
+When activated, access to most USB mass storage devices (thumb drives, magnetic usb drives) is enabled.
+
+### ufi-drv `CHUFIENABLE`
+
+The `ufi-drv` system can be enabled with the HBIOS config `CHUFIENABLE`
+
+When activated, access to 3.5" Floppy USB devices will be enabled.
+
+### keyboard `TMSMODE_MSXUKY`
+
+The `keyboard` system can be enabled with the inferred config entry `USBKYBENABLE`
+
+This config item is not to be directly set, but is activated via the TMS keyboard driver
+
+Example configuration, combined with the TMS VDP module driver.
+
+```
+TMSENABLE    .SET   TRUE              ; TMS: ENABLE TMS9918 VIDEO/KBD DRIVER (TMS.ASM)
+TMSMODE      .SET   TMSMODE_MSXUKY    ; TMS: DRIVER MODE: TMSMODE_[SCG|N8|MSX|MSXKBD|MSXMKY|MBC|COLECO|DUO|NABU|MSXUKY]
+TMS80COLS    .SET   FALSE             ; TMS: ENABLE 80 COLUMN SCREEN, REQUIRES V9958
+TMSTIMENABLE .SET   TRUE              ; TMS: ENABLE TIMER INTERRUPTS (REQUIRES IM1)
+```
+
+When activated, usb keyboards can be used as input devices.
+
+### Force activation `CHNATIVEFORCE`
+
+The CH376 module, during a cold power on boot, can take many seconds before it will
+respond to the CPU.  As such, the CPU may fail to detect the presence of the module.
+
+A manual reset (without power cycling) generally enables detection.  The config entry
+`CHNATIVEFORCE` can be enabled to force the CPU to always wait for the module to come online.
+
+
+### eZ80 support `CHNATIVEEZ80`
+
+If you have the eZ80 CPU installed with onboard USB firmware support, you 
+can gain performance by delegating HBIOS to the firmware implementation.  To enable
+delegation, enable the config entry `CHNATIVEEZ80`
