I am pretty new to this, and I am trying to learn about what specifications I should be looking for when doing a chip replacement.
For example, lets say I know 100% sure my BIOS chip is broken. And I would like to replace this broken chip with a blank chip, which I will later reprogram.
How do it know what empty chip to order on-line, cause there are many different specifications with every chip?
Lets say my original iMac uses this chip: MX25L3205D.
Does it mean that any blank chip which has 25l32 in it can be used?
