[Coco] fpga coco3 sdcard os9 boot

[tim franklinlabs.com]

   Camillus,
   From my time spent over the last week trying to get this to work, it's
   not ready for prime time yet. Several files needed are
   not (as of today) posted. I will e-mail you the files if you want and
   if Brett or Gary give me the permission too. I'm sure they
   will. But, they are not 100% working. You still have to be connected to
   Drivewire for it to work. At least with the files I got
   from Brett. I saw Gary completely disconnected from DW at the fest but
   he hasn't released it yet.
   As for the step-by-step instructions, I'll give it a go...
   These instuctions assume you have general knowlege of programming the
   DE-1 FPGA. Many details were left out. If you need
   further help, read the quartus manuals.
   Step 1     Install the CoCoFPGA core CoCoFPGA.POF onto the DE-1 program
   flash (not the 4M flash). (Need to send this file)
       Note: The version of the POF is unknown as this file was sent to me
   by Brett.
       a. Put the DE-1 in write mode (switch on unit)
       b. Use the Quartus II programmer to "burn" the firmware to the FPGA
   system.
       c. Put DE-1 back into write-protect mode (switch on unit)
   Step 2    Install Brett's ROM image at location &H31000 in the DE-1
   Flash.
       Bretts code acts like a ROM pack and is located in one of the
   virtual MPI slots of the DE-1
       a. Install the DE-1 Control Panel (DE1_USB_API.sof) using the
   Quartus II Programmer
       b. Run DE-1 Control Panel application DE1_Control_Panel.exe
       c. Erase the FLASH.
       d. Burn file _DE1_FLASH.BIN to the flash at offset $00000
   (Important: file length switch ON)
       e. Burn file _ROM.BIN to the flash at offset $3fc000 (Important:
   file length switch ON)
   Step 3    Burn the SD Card image to the SD card at offset $000000.
       Note: This step, you are on your own. I did this using some custom
   software I wrote for my company a few years back.
   Step 4    Connect Drivewire with some dummy disk file installed. It
   doesn't matter which format.
   Step 5    Enjoy.

   If you want me to send you the files, I will after I get the OK from
   Brett or Gary.

     Hi all,

     I'm trying to follow the Nitros9 SD booter thread, but I got lost a
     long time ago.

     Can someone pls get this all in a step by step instruction guide,
     for us starters...lol

     The jargon in the mails is gibberish for me.

     So anyone please?
