DIY_EFI Digest V2 #261

[John Hess]

Reading the PROM is actually quite simple.  Get a PROM 
Reader/Programmer.  Get a dual inline header strip.  Bend the long 
pins outward so that they can be plugged into the Programmer socket. 
 Plug your Memcal onto the pins sticking up (the pinout for the Prom 
is the first (I think 28 pins) of the header.  Cut off the rest of 
them and you can read (and burn an erased memcal).  The trick is not 
reading or burning the EPROM;  but, in knowing where the various maps 
are on the PROM and what they are doing.

Agreed!!  Mr. Peterson didn't get rich by being stupid.

It was informative to me with details I didn't know.  I was unaware 
how
to read the prom.  Reading the prom has been mentioned on the list.
Someone has mentioned having files of various proms. Now I know one
method of doing it.  I also know I'll never have the resources to do 
it
myself.
