Can we get a positive answer on the resister situation?
Can we get a positive answer on the resister situation?

No one has said positivly exactly how to short the resister pads for the onboard ide. We all know what the resisters look like and so forth, but to the poeple who have just shorted across ---> did you do it pad to pad or group all the pads together??

Don't short all of the signals together. Those are your HD connector signals!

That would be like soldering all of the pins on the back of your HD together.

I soldered very thin wire (cut to the appropriate length) to short the pads.

That helps a little bit.

I got my 2 ik resisters on.

Now there are 6 squares left, each square has 8 pads 4 across from the other 4. What you are saying is that I need to jump each pad to it opposite giving me 24 single jumps??? of 6 jumps total, on glob for each square to jump them together...

Damn.. I knew it couldn't just be easy for once. I suck big at soldering, and those little surface pads are small. It took me all damn day just to get the header in properly... Well, I'll be back in about 3 hours..

Peace Out. Thanks.

Pic of a WS with onboard IDE resistors soldered in:
http://linux-hacker.net/websurfer/images/ide-resistors1.jpg

I would use wirewrap wire if I were to short across them. I will try to indicate which way to jumper in the pic if I get time.

Easy way to tell, one side connects to the connector, the other to the controller, when you find 5 or more like that you get the general idea.

Look at "RN11" for a example, four traces come from the IDE connector, jumper them across to the controller side.

well first off they all called resistors...just so we all know hoe to spell them. second, who did the resistor pack install that's in that .jpg? it looks good and i'd like to attempt it myself but not sure what value/type of resistor pack to go with. who's a good source for those parts?

R99 and R100 are pull-ups to +5V, so anything between 1K and 20K would be OK for what we are doing. That would translate to "102" up to "203" in little tiny part numbers.

The packs can be from about 22 ohm to maybe 100? 33 was a good choice someone suggested, the IO uses 22 on their IDE. They add RFI "protection" and maybe if you plug it in backwards with power on it will save you.

That translates to "220" up to "101" in little tiny part numbers.

You can find these on old dead $1 swapmeet hard drives and boards if you look. That is why I am saying that the values can vary, it's not all that important since the cable run is very short. This is all 5V logic signals.

The ones you see are 33 and 1K, but engineers have this stuff laying around.

COM1 is attached and working in the pic, with the addition of U10, it's the same as U17. Same pinout at the connector as a normal serial.
