I have a Digital Audio 733mhz and was given a Giga Designs CPU to use as an upgrade but without any instructions. When i opened the machine i saw a plastic cover over where i assume the CPU is - i have upgraded other machines but am unsure how to remove the plastic - also is there a firmware or any other action to be done before. thanks in advance - ronald -------------- next part -------------- An HTML attachment was scrubbed...
