abit an7 and prom1 boot problem - plz help!!

[dekkard]

ok, hello everybody! i know that this is a prom2 board but i beg your pardon and hope that somebody can help me...

i operated a prom1/nf7 combo for about 2 years without problems. now my old mobo died and i bought a new abit an7. this was where the fun started. after setting up the new system and booting for the first time, the prom seemed to be unable to hold the system in reset state, resulting in an immediate boot up of the system - not good

i rechecked the cables numerous times, but everything connected properly, even did a bios upgrade (1.8), but nothing worked. after pushing the powerbutton, the system boots immediatly.

2 more facts i noticed:

1. when i press the power or resetbutton, the system boots/resets not on pressing the button, but on RELEASING it. may this be the cause of the problem? and if, does anyone know how to solve it?

2. the prom1 itself seems to function properly, i clearly hear the relais' clicking sound at -33°C (when the system is supposed to be released from reset state) and the following reduction in fan speed.

so, somehow, the board gets no reset signal or misinterprets it... has anyone experienced such a problem or knows how to solve it??

every help appreciated, thx

If you can put up with the hastle - I've seen it suggested that you simply run the PC and Prom seperately - when the temp is right - then fire up your PC - it's a nause, but a good temporary fix!

thx for your reply, cavemanep.

i also thought about this, but how do i do this? if i just shorten the two "power pins" of the prom cable, nothing happens. it seems there must be some electricity in the cable, even in standby. this would be enough of a solution to me, if i could get it to work.

What I read was:

1. Power your PC as normal.

2. Run your promie as normal, but plug an old PSU into the 12V (I suppose you can use the old 'paperclip' trick to power on your old PSU.

(The guy who did this has a 12v transformer for the prommie, but I'd be a bit nervous about doing that unless I knew exactly what volt/amp etc was required!)

So, the order: Power up the old PSU - Power up the Prommie - wait for -33C, power up the PC

It's a pain, but a good temporary stop gap!

ok, silly me, in my hassle i didnt think of the other connector too having power anymore... problem is, i've got not old psu at hand atm, an this method also sounds a bit too annoying to me. sorry for being that demanding and thx for the help, but is there no other workaround for this?

If you press and hold the reset button on your new mobo what happens? (ie can you manually hold it in reset?) - not sure how it works, but might be worth a play - if you can just get away with holding down the reset button until it hits 33C you'll be laughing - not tried this, but might be worth a go?

I'll have a look around and see if I can find any other solutions - I've PM'd you with something that might help!

 

[dekkard]

that's exactly the problem. if i hold the reset button, nothing happens... just as i release it, the unit resets. so i would have to release it all the time to keep it in reset state...

Hmmm... as I mentioned in PM - probably easiest to flog the mobo and get a nice NF7-s ver2 - probably only lose about £10 all in if you shop around!

I'm sure you've seen it in the other post, but this might be a good solution for you as well:
