If you are doubting the need for EEPROMS for kickstart 3.1 Roms, then why are the two you just sent to me (A1200) EEPROMS ?

Also, I'm suspicious that the metal shield may have been the reason for the problems I had, what exactly does it do? Can anyone give a brief explanation of why it's needed?


The metal shiels acts as 1) a total grounding and 2) RF shield.. stops any RF interferance.
