Parallel port settings

[mondoguitar]

I just bought a new computer with an onboard parallel port. My old computer worked 100% of the time (until I fried it and bought a new PCI version) Then it was sparatic and would only work 30-40% of the time.

WELL... now I have a brand new computer and i'm STILL having issues of it only working from time to time.

Should I have the BIOS settings set to ECP+EPP, bi-linear or something else?

Any ideas would be much appreciated.

PS. I'm using a buffered jtag with 9V power supply.

Thanks.

how about just going into jkeys and set it to 0x378? we are gonna make a good tester out of you yet mondoguitar

Gee thanks M5runner! please tell me what the LPT address has to do with the Parallel Port mode at ALL?????

Don't be so quick to judge me dipshit. I may not have many posts on THIS forum, but I've been doing this for four years now and have helped my share of people without passing judgement. I don't see anything helpful in your post but critisism so keep it to yourself.

My question is, what possible reasons could be causing the on-board parallel port on my NEW computer to only work part of the time, when my old computer's worked ALL the time until it conked out? That simple. If you don't have any constructive ideas, then shut it. I've had it with these forums that pass judgement on people based on their number of posts!

I apologize if I already asked this question somewhere else in the forum. I posted it in a few other places and possibly lost track. But geez, relax, it's supposed to be a hobby not a place to take out your anger!

[m5runner]

dude first off you need to relax ok. it's what someone with personality calls a "joke". you think i give a shit about how many posts you me or any other guy on here has? fuck posts! if you want to take it personal then i can take it there. i can always ask you if you are brain dead or some shit to where you can't figure out why your LTP1 doesn't work and can't think of creative ways to test it. i won't shut my mouth for you or anyone in this forum. if you need help, i will help but don't come at me like i am supposed to care what you or anyone else here thinks of me.....i will still sleep real good tonight, trust me. get over yourself and fix your printer port. pan001438 posted pretty much the same thing i did. say something to him, he has over 1,000 posts....maybe he might care

M5runner, you didn't post ANY information, you said "start testing and fix your printer port", gee thanks!

pan001438 at least gave me somewhat of an answer to what I was looking for more specifically. Do you think I haven't already tried going into the BIOS and tried different things there and in device manager??? NOTHING works for me! So tell me how you want me to fix it! It's a brand new computer!

Anyways, could a MOD just shut this thread down, it's going nowhere useful!

For what it's worth I use ECP parallel port, with the "never use Interrupt" checked in device manager, using Windows XP Pro corp edition.
Done 300+ mods like that no problems.......

[mondoguitar]

Thanks skinnerd, that is what I have been trying. I can't figure out why it will read the flash chip at first... even erase it... but then when I go to program it, it gives me a "CPU register error". Usually unplugging the IRD and re-doing the process 3 or 4 times fixes it and it eventually kicks in for good.

I would just like to get to the bottom of it. Is it a power issue, or a conflict issue of some sort.

[m5runner]

the guy expects me to help after he flames me. what a guy. you will learn about me real soon. i am the bastard child of this forum. well if i were in your shoes, maybe i would find out what pin does what on the DB25 connector and who knows, maybe putting a meter to it. i would also look behind the connector on the mobo and look for anything that might be burned out, check the properties for IRQ conflicts, uninstall the port and let windows reinstall it, plug a printer up with a parallel connection and see if it works....get where i am going with this? well if you tested all these variables, maybe your port is bad and you should consider trading out the mobo or something.

GUY!!! I have tried all this crap!! comprende?? IT DOESN'T WORK! Yes a printer works fine! Yes the connections are all fine! And PLEASE quote me... exactly WHERE did I ask for more of your "help". You come off as a young smart ass who obviously knows it all.

No wonder you have so many posts if you're going around being sarcastic with people.

M5runner, I don't need your help, got it? :flipa: Good!

I thank the people that did give an attempt at some helpful advice for me.

How long are your jtag leads?? not all parallel ports are created equal, and jtag leads over 6 inches lond don't seem to work well at times....
I have very short jtag leads and sometimes if I let the jtag get too close to the power supply section of the receiver I will get erratic problems....

[m5runner]

now we are getting somewhere....printer works, get the properties of the port and see if they have those settings in jkeys. if i am not mistaken, i think you can type the address in manually. does it become LTP2 or what? disable the one u cooked (i don't even want to know how u did that) and see if the PCI card takes the properties and becomes the default LTP1. my posts suck huh? poor me...don't care about them

pretty good info flashf....you taught me some new shit today. keep up the good work. i think she got it to work though and she didn't even post what the problem was to help out the next guy that runs into the same shit.....go figure.

I've found some interesting info in this thread, aside from the bullshit and sharp jabs, but it didn't quite get to my problem, I've done lots of tsop reading and writing so everything is connected properly but I get the device not detected, when I do my port diagnostics I find no check mark in the tdo (pin 13) If I broke my parallel port can I fix it? If yes How? I'm an old man so please be gentle.

without looking at a DB25 port on a mobo ican tell you that there are a few resistors behind it (surface mount). see if you can get values on those with your meter. try uninstalling the port and reinstalling it first and foremost then check for damaged components on the mobo behind that connector. let me know what u find.

Thanks m5runner, I'll check it tomorrow and report my findings.

This is already posted, but I'll repeat for clarity, (I hope)
Probably the easiest way would be to dis-able the on board LPT port in the computer bios, then purchase an add on LPT port, relatively in-expensive, and configure it as your LPT1 port, relatively easy.

[borg1]

You phrase the question like your old computer had an ISA interface. You did not just image the old drive to the new one?

As an aside, the last 3-4 laptops I have connected to a JTAG have had LPT1 set to Bi-Directional in BIOS, and this setting has failed to connect every time. Set to EPP.

Also, the CPU register error does not read like
BAX-xxxxxx CAX=xxxxxx DAX=xxxxxx EAX=xxxxxx
does it?

If it does... you gotta bad processor. (an Intel?) [8 out of 10 odds, if not, it is the mobo]

[leebo]

Thanks for the trouble shooting tips, it's much better when you know where to aim. I found that by removing my parallel port and re-booting the check comes back in the tdo, also by simply refreshing it in device manager it comes back, the pc is fine, I connected a buffered jtag to a dish receiver and all is well, I haven't isolated the problem yet. (but I will) The receiver works, I'll build another jtag and try again. Maybe it's just being mean!! Thanks again.

[m5runner]

yup, no problem. sometimes uninstalling and re-installing things help. good to know it was just that
