<trash me!>
I want to read a 2764 eprom by puting it in the pc's empty socket
and capturing the code with debug. Somewhere I read that the empty
socket is checked to see if it is really empty. If it returns garbage
DOS continues on its merry way. If it contains a signature then
some point in the prom gets the current instruction pointer control.
My problem is that I cant remember the details, so it is possible it came
to me in a dream! I cant find any reference to the F4000 start address
nor any other reference in the Tech Ref BIOS.
If someone in netland can set me straight and point me to the information
I'd be thankful. Feel free to post as followup, others may like to know.

[This line seems to be more of a tradition now than necessity} There was an article in SOFTALK about 3 to 6 months ago about the empty 5th ROM socket in non-XT pc's. Placement of a correctly programmed ROM will allow you to boot from a drive C hard disk via a built-in check that the BIOS does to code that is supposed to be there. Perhaps that is where you read it?
