Home / I-Opener Areas / I-Opener Technical Info Reference (MODERATED) Program the V3 Sandisk from IDE Header w/IO Power Off Possible way to Mod V3 IO w/out removing bios epoxy

Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) iambarry Profile I haven't tried this yet, but it seems like the V3 IO Sandisk could be programmed by connecting a second PC to the IO IDE header with the IO's power off. The sandisk should get power from the IDE power pins, and all the data pins should connect up to the header. The second PC would see the Sandisk as a slave IDE device. We could then put linux (or whatever) on the sandisk, boot the IO, and re-program the bios. This may be how they program the Sandisks at the factory. I plan on trying this method out tonight. Anyone know any reason this shouldn't work? Will I fry some other components by connecting a second PC to the IDE header? --iambarry 05-03-2000 08:16:53

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) -pyr- how do you plan to power the sandisk? If you attach an adaptor you run the risk of frying it if you plub the power into a 12v power supply, but if you dont, there is no power to the sandisk. 05-03-2000 08:37:05

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) iambarry I have a 3.5 to 2.5 IDE adaptor. The extra pins on the 44pin IDE are power. I'm thinking that this should connect up to the Sandisk, and power it. Think this will work? --iambarry 05-03-2000 10:31:16

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) DKnight iambarry, it's possible but you have to ask yourself where else is that backfed power going ?, it may power up the whole io it may fry the controller, the sandisk doesn't necessarly get its power from the same location as the IDE header does, so it may work, or not and it may toast the IO. this is better tested by someone who has an already damaged IO, there are several who have posted claim's that they have a broken one. Here is an open request to all that have fried IO's :do any of you want to try it ? You have nothing to lose and several people have something to gain from the info. 05-03-2000 14:50:23

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) Dknight also,if anyone tries this,remember you HAVE to invert the pins BETWEEN the IO and the adaptor. most adaptors have lots of pins tied to ground! 05-03-2000 14:52:07

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) NoNo Before you get too excited, check the threads. This topic has been fairly hot until about four days ago when things came to a halt. There are some problems. The main one being that it did not really work between to old PC's (the tesbed of choice to avoid risk of damaging valuable hardware. The Sandisk will be even harder; better read the specs on the chip. You should not assume that it is precisely like an IDE drive; there are several modes to the Sandisk, including memory mapped. It has also been reported that shooting power into the IO via the Sandisk port will fry the IO. Tread carefully on this one, and get some experience first using two old pc's and a couple of cheap hard drives. 05-03-2000 22:07:36

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) SanDisky+OHIO iambarry You are in the 'Technical Info Reference Area (Moderated)' and are making unfounded claims and/or questions about something that should be hashed out in the 'Technical Area'. DKnight If the i-opener has been fried and does not power-up, then how does one go about testing the SanDisk? Your logic is irrational. How do you suggest eliminating contention from any support circuitry? If you can get this to work, I will give you a blowjob! BTW, that blowjob would consist of cleaning out my septic tank on the hottest day in August. 05-04-2000 16:53:11

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) iambarry OK; there is some good news and some bad news... The good news is, I'm not going to be cleaning out any septic tanks... The bad news is it looks like I fried the sansdisk. The IO still boots to the bios, but doesnt find any disks. --iambarry 05-05-2000 14:36:32

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) dknight sandisky+OHIO, I wasn't going to post to this thread again because you're right it IS in the wrong area,however I noticed that it was back at the top anyway so what the heck. First I do not know exactly (or even remotely) how the sandisk is wired to the controller however since it emulates a HD it is reasonable to assume that it MIGHT have been wired in parrelel to the IDE header just like a regular 2 device IDE bus. If that were the case it was possible that attaching to the 44 pin ide MIGHT have both provided power to the sandisk and allowed to read it with another pc. that is why I suggested a damaged IO, some of them have BIOS socket troubles or soldering mishaps. Second: I really didn't think it would work and I didn't know if iambarry was a troll,serious,kidding or a newbie. The main purpose of my post was to give imbarry the benefit of the doubt and discourage him from trying it on a good IO. While I was at it it made sense for someone with a damaged unit to give it a shot anyway as there would be little to lose in trying. Third : flames are expected on a BBS it's all part of the game,but man what you said was just not riiight, I mean dude,I was eating dinner when I read your post! 05-05-2000 15:53:35

RE:Program the V3 Sandisk from IDE Header w/IO Power Off (modified 0 times) dknight BTW,no offense ment to imbarry :) 05-05-2000 15:59:17
