100 Ohms. They go to pins 1,3,5,7,9 and 11 on the DB's pins.

Pin 25 is the actual ground connection of the printer port connector. You solder 18 -25 together to maintain a good ground condition through the printer cable.

first of all, i ant thank everybody in this forum especially in this topic. i was so happy to read everything wroten here.

i succeeded to run the DOS jitag program. i've used commands to read my dreambox information and to change my MAC address. At the end of the process i getthis:

Tuner Type alps
Erase Flash done

nothing happens after that.

now i want know what should i do to write the alps flash throught DOS program.

Could you help me in this plz??

thank you in advance.

Hi all,
thanks for the info, I finally managed to bring my DM500 to life again.
Following a quick summary of my way doing it:
1) the 100Ohm scheme is correct, BUT cut your jtag cable as short as possible and less than 10cm in any case.
2) both win and dos initialized the cpu and flashed the box. But it seems I couldn't find the right alps image for the win prog so I used the dos one. After successful flashing with jtag_win the box just didn't want to light up, e.g. no green led.
3) I found it annoying matching the right sequence of pressing "Connect" and plugging the power cord with jtag_win, so I build a small switch with a piece of cable that worked just fine (seen on 2nd pic).
Also the LPT on my laptop didn't support ECP+EPP so I used my desktop.
4) in the dos app you can set your own MAC address by editing alps2.bat
5) If your box is alive again flash a new linux image right away. I didn't, so half an hour I had to grab the soldering iron again.

Some pics added.

JTAG for WIN is found here in the forum.

P.S: Mods, if linking like above is incorrect pls remove it, rest google for "jtagdm500aio.zip"

Hello,

I always get same errors, which I can still make this error do not come Erase Flash done

 

[hougie1962]

exactly what resistors do i need and where can i buy them cheers paul

 

[e.v.k]

does not have an idea which that are none

 

[sydnebluetoto]

pls help. i just want to know how many resistor i need, because i am so confuse, and which number i need to connect to those resistors.

 

[el paso]

i found eprom cmos programmer on ebay in u.s.

about $150.00. there are several to choose from to

suit your needs. it is easy to use.

Hello!

One of my dm500's jtag solder point has come off! Is it still possible to jtag the box? I cannot solder the wire to that point anymore!

Thanks
