I posted this on a older thread I have and just wanted to make a new thread in the event that someone has some questions later in life this might be easier to come across.
Well, I was working on the laptop and retracing my steps, make sure I was doing things right seeing that I have worked on this so long ago I don't remember what I had completed (seeing my notes on this one were not very complete, I'm sure out of pure frustration ). So, I want to make sure I'm shorting this BIOS chip properly, I found a webpage that says you have to short either 2 & 7, 3 & 6 or 4 & 5... I have done all 3 of these combinations with no results! I believe I have found the schematics for this chip, but seeing the actual chip is obsolete I'm going off of an ROHS version that I think is the same. Also, I took a picture of the chip itself for ID purposes.
If someone could please help me and just run through the process of shorting the chip to verify that I'm doing this all properly and to make sure I have done the right pin combination, I would be in debt to you! lol! Thank you for all the help that everyone has provided thus far!
Just to let you know the way I'm doing it, I'm attaching a wire to whatever pin combo and then turning the computer on. Maybe I don't understand why these combos, from what the schematics shows, it really doesn't make any sense to me. Also, this laptop has NO BIOS battery but a larger surface mounted cap, I don't understand how the settings stay set if there is nothing there to keep power going to it. Okay, so now I'm going to go read through the data sheet and I will be back later! Thanks!
Thank you in advanced,
Peter
