== Firmware ==
Updating (or downgrading) a firmware is done by unpacking the update zip file to the root directory of the microSD card (from a PC). Then insert to the M4 and powercycle the CPC/M4 board, after about 20 seconds it should be updated. Verify with |version command.
Latest firmware version can always be obtained via |upgrade command (no need to use PC, as long as CPC is setup to the internet).

'''Please notice, on M4 boards shipped after 2016-10-01:'''

Due to a new flashchip on the wifi-board, do not use firmware versions lower than v1.0.9. If done by accident, use v1.0.9 or higher to restore it.

'''Modified lower ROM for CPC6128''' users, who cannot override AmsDOS (ROM 7) with the M4 ROM, using this patched lower ROM, M4 ROM must be in ROM slot 6.
It will be initialized instead of rom 7 and provide better compatibility with games and higher himem.
It's recommended to upload the original AMSDOS (or Parados) rom to rom slot 6, then it will be available when typing |M4ROMOFF.

[[CPC M4 xfer tool]]: Command-line tool that allow to send files and receive from an M4 Board. Possibility to add an AMSDOS header too.

[[M4reconf]]: A native CPC program to write romslots.bin and romconfig.bin with the romboard (to use other M4 rom configuration).

[[Media: M4 Board relay rom.zip | M4 Board relay rom ]]: When moving M4rom out of position 1-7 / 1-16 it will no longer be initialized, therefore this rom should be placed at rom7 or lower. This is if you want to use 32 roms of XMEM and map M4 romboard after it. You should program the XMEM or other romboard with M4 bootrom in pos 1-7, it will look for M4 rom from 1-127 and initialize it + pass commands through to it. '''NOTE THIS IS OUTDATED, only use for early versions of the M4 firmware (v1.0.1)'''

== Technical information ==
Structure for romslots.bin & romconfig.bin under m4 directory are: 
romslots.bin 
Contains 32x raw rom data (no headers). To locate a rom in the file, use: 
offset = slot * &4000 

romconfig.bin 
Header: 

<code>int totalRoms; // 32 (early versions of the firmware had only 16)</code> 
<code>int m4RomNum; // M4 rom to map rom number 0-255</code> 
<code>int m4RomEnable; // M4 rom enabled</code> 
<code>int romRangeStart; // start mapping roms from</code> 
<code>int lowerEnable; // lower rom replacement enabled</code> 
<code>int lowerSlot; // which slot maps lowerrom (0-31)</code> 
<code>unsigned int reserved[2]; // set to zero for now</code> 
 
Then for each rom (repeated 32 times): 
<code>char updateflag; // 0 = no rom present (or disabled), 1 = rom present (enabled), 2 = New rom will be flashed into M4 internal flash, 3 = remove rom</code> 
<code>char name[32]; // name of rom to be displayed in webinterface</code>

'''Modified lower ROM for CPC6128''' users, who cannot override AmsDOS (ROM 7) with the M4 ROM, using this patched lower ROM, M4 ROM must be in ROM slot 6.
It will be initialized instead of rom 7 and provide better compatibility with games and higher himem.
It's recommended to upload the original AMSDOS (or Parados) rom to rom slot 6, then it will be available when typing |M4ROMOFF.

[[CPC M4 xfer tool]]: Command-line tool that allow to send files and receive from an M4 Board. Possibility to add an AMSDOS header too.

[[M4reconf]]: A native CPC program to write romslots.bin and romconfig.bin with the romboard (to use other M4 rom configuration).

[[Media: M4 Board relay rom.zip | M4 Board relay rom ]]: When moving M4rom out of position 1-7 / 1-16 it will no longer be initialized, therefore this rom should be placed at rom7 or lower. This is if you want to use 32 roms of XMEM and map M4 romboard after it. You should program the XMEM or other romboard with M4 bootrom in pos 1-7, it will look for M4 rom from 1-127 and initialize it + pass commands through to it. '''NOTE THIS IS OUTDATED, only use for early versions of the M4 firmware (v1.0.1)'''

== Technical information ==
Structure for romslots.bin & romconfig.bin under m4 directory are: 
romslots.bin 
Contains 32x raw rom data (no headers). To locate a rom in the file, use: 
offset = slot * &4000 

romconfig.bin 
Header: 

<code>int totalRoms; // 32 (early versions of the firmware had only 16)</code> 
<code>int m4RomNum; // M4 rom to map rom number 0-255</code> 
<code>int m4RomEnable; // M4 rom enabled</code> 
<code>int romRangeStart; // start mapping roms from</code> 
<code>int lowerEnable; // lower rom replacement enabled</code> 
<code>int lowerSlot; // which slot maps lowerrom (0-31)</code> 
<code>unsigned int reserved[2]; // set to zero for now</code> 
 
Then for each rom (repeated 32 times): 
<code>char updateflag; // 0 = no rom present (or disabled), 1 = rom present (enabled), 2 = New rom will be flashed into M4 internal flash, 3 = remove rom</code> 
<code>char name[32]; // name of rom to be displayed in webinterface</code>

Duke: /* I/O Port Summary */

This is a list of all known I/O ports of the Amstrad CPC, including all [[Peripherals]]. For a list showing only the built-in standard addresses see [[Default I/O Port Summary]]. The original list of I/O ports was taken from the [[FutureOS]] handbook.

== More Ports ==

Some more I/O addresses (which aren't included in the above list yet) are here:
* [[Schneiderware Summary]]

== Other I/O Ports ==

A number of peripherals connect to the joystick/printer ports, and so, they do not include "own" I/O addresses. This includes hardware ''other than joysticks/printers'' - for example, mice, robots, audio devices, and simple network adapters. For a more complete list, see corresponding sections on [[Digital Joysticks|Digital Joystick]] and [[Printer Port]] pages.

Aside from I/O addresses, there are some other important I/O signals, for example: [[NMI]] or [[External Interrupt|INT]].
