This package contains precompiled .hex files of MIOS V1.9g for various PIC
derivatives.


Note that in most situations, only **one** .hex file needs to be 
uploaded via MIDI. Please read this README carefully in order to 
select the right binary.

Oversight:
   A) Update MIOS V1.9 to v1.9g
   B) Virgin PIC18Fxxx, own PIC programmer available
   C) Update a PIC with Bootloader V1.1 and MIOS V1.8 or older

-------------------------------------------------------------------------------
A) you've already installed MIOS V1.9f, and want to update to MIOS V1.9g

Thats the common case, you have to upload one of these files 
via MIDI as described on the http://www.ucapps.de/mios_bootstrap.html page
depending on the PIC derivative you are using.

PIC18F452:
   -> pic18f452\midi\mios_v1_9g_pic18f452.hex

PIC18F4620:
   -> pic18f4620\midi\mios_v1_9g_pic18f4620.hex

PIC18F4685:
   -> pic18f4685\midi\mios_v1_9g_pic18f4685.hex

-------------------------------------------------------------------------------
B) You have a virgin PIC18Fxxx device and want to burn the bootloader with your
   own PIC programmer.

This step isn't required if you got a preburned PIC from SmashTV or Mike!

Burn:
   -> pic18f452\burner\bootloader_v1_2_pic18f452.hex
resp.
   -> pic18f4620\burner\bootloader_v1_2_pic18f4620.hex
resp.
   -> pic18f4685\burner\bootloader_v1_2_pic18f4685.hex

into the PIC with your programmer.

Thereafter upload MIOS via MIDI as described under step A)

-------------------------------------------------------------------------------
C) Update a PIC with Bootloader V1.1 and MIOS V1.8 or older

This MIOS release doesn't contain a special binary for bootloader
update V1.1->V1.2 anymore. If you still use a PIC with old bootloader
(which is obsolete since more than 3 years now), please contact
tk@midibox.org to get individual informations about the update path
(files are not officially released to avoid unnecessary confusion).
