ok i'm an idiot first off. i don't have the manual for this motherboard, AND i lost the sheet of paper where i wrote down how everything was connected when i took it apart. and i forgot to plug in all the little colored wires: reset switch, turbo led, etc etc. so now i'm kinda f-ed cuz i'm not sure where some of these wires go, or which pins are hot and which are grounds, etc. i'm trying to get a hold of a manual that is (hopefully) for the same mobo, but i'd rather get it fixed now if possible.

anyway, if someone more experienced can give me a helping hand or just tell me to work harder to get the manual then i'd appreciate it.

the box is a p90 produced around 1995. it's in a midtower case

this is what the pin strips on the motherboard look like


T-LED, HDLED, KEYLOCK, RST
110 010110 111010 11

1101 0111 011101 011
SPKR, FAN, IR, SLEEP

Legend:
0: open hole, no pin
1: pin

the above is how the strips are oriented on my board, i even put the labels in the same place as they appear on the board. the first pin strip runs long the bottom of the motherboard in the front corner (front of the at case), and that is what they look like from upside down. the second strip runs along the front (again, front of the case) edge of the motherboard, and they run as if written along the edge from bottom to top of the case.

the wires that plug into them are fairly standard i think, but they are:

Speaker: 4 pin jumper with 2 wires, black and red

HDDLED: 2 pin black and red

TurboLED: 2 pin black and yellow

Keylock: 2 pin blue and black

TurboSW: 3 pin red, black, and green

PowerLED: 3 pin with two wires, green and black

RestSW: 2 pin black and white


I can't even get the damn thing to post right now.. though i thin if i can get the reset switch plugged in riht that might fix that, i'm not sure what other wires might be preventing it from doing anything. anyway, any help great or small would be much appreciated.

wow it really helps to have the power supply for the mobo fully seated http://www.linuxnewbie.org/ubb/biggrin.gif it'll post, i can boot off of a floppy now, but i still don't know where all these damn wires go... the bios gives me a "Disk not ready" error on the hdd.

Well, I have never had a problem with the "case doohickeys" (technical term) being connected or not.

Why not find out who made the mobo and what model it is, and see if they have a online manual?

Check the fcc id number, it will tell you the manufacturer - there are a few lookup sites online, but start with www.motherboards.org (http://www.motherboards.org)

well, yer right, i don't need any of the doohickeys hooked up, i had my secondar and primary ide cables flipflopped as well. so it works... i even got the speaker and the reset switch hooked up right... there's just no lights on the front.

i tried a couple look up sites, i couldn't figure out what kind it was. anyway, no big deal, s'usable now. now if i just had time to play with it more. sigh.

thanks though.

can't give specifics, and you might be less willing to experiment than i would be, but i can offer some observations.
i have yet to see a plug that fell off the side of the header; that is, if the plug has space for 4 pins, it'll likely occupy 4 pins of space on the header.
the speaker looks like it goes on the lower left of your diagram. polarity is not a great issue - if it doesn't work in one position, just twist the plug a half-turn and try again. the missing wires may be all the clue you need to orient the plug correctly the first time.
reset probably to the upper left - since it's just a momentary-contact switch polarity is not an issue.
LEDs are gonna need two pins and polarity does matter; if you plug one onto the header incorrectly it just won't light up - reverse the plug.
plugs should go onto the header in the order indicated on the mobo, going from left to right of your diagram. start at the left with the indicated plug and attach them in order at the first set of pins that match the plug for each plug.
note that this is only what i would do and i offer it only as a suggestion. i can offer no guarantee!
good luck http://www.linuxnewbie.org/ubb/smile.gif
