Bios pin 35 - alternative place to connect? - segadreamcaster - 05.05.2012 19:19
Hi again,
Ok, this one is a long shot, but I damaged a dreamcast mobo when I initally attempted the bios upgrade and am now unable to attach pin 35 as the board there is too damaged.
Does anybody know if there is an alternative palce on the board I could attach a wire to?
Thanks again
Cheers

Ah, I feel your pain....with any luck someone might have a solution

Well, I found the solution to my problem anyway
With the help of this photo:
I was able to trace pin 35 which has another link under the chip (as you can see in the photo) to the other side of the board and then connect a wire...and bingo...working again
Unfortunately Gromber, I can't see an obvious solution for you as there is no visual trace of leg 22 on the picture
Goodluck with solving your problem

Well, here are two images of where I needed to attach pin 35 to. I did it by carefully matching up the terminal pattersn on each side of the board. It would have been easier to poke a tiny piece of wire through but that would have meant removing the chips entirely
