BIOS Updates forum

I have never tried desoldering relatively micro sized chips before. I have experience in soldering with just fixing simple circuit failures. Probably i would either ruin the board or the chip while desoldering. I really need more electric and electronic knowledge, pure softwate skills already proved ...

Thank you very much cp. You are indeed a Master Flasher. I've bought some related material, now looking for a suitable EPROM chip. I'm also thinking to buy a Willem Eprom programmer. Would you suggest it?

And also i'm thinking about other option due to i may not be able to find a suitable chip ...

I checked all the capacitors before, they all seemed to be ok in appearance. But thanks much for the link, it may become handy in the future.

It follows as :
SST
39SF020

Thanks for your reply cp, but i don't have any idea about which is the "chip enable pin" on this BIOS chip. I'll try my best and search for it. I'll also consider about gaining some soldering skills. By the way, wouldn't i harm the chip(or the data stored in) while soldering or desoldering it?

And ...

I like to play and modify hardwares. Recently i bought a faulty board, thinking i could fix it with some luck, to make some modifications and test some hardware on that. You know the starter of so-called revolutionary and life saving GA-BX2000 series dual-bios boards...

The board is a GA-BX2000 ...
