EDD is short for 'Enhanced Disk Drive Services' and is an extension to the
BIOS that allows the BIOS to use drives larger than 8 GiB. ("Extended INT
13" and "packet interface" are just other names for the same thing.)
It was introduced in 1995, so almost all motherboards produced after 1995
will have support for it. You motherboard is thus probably much too modern
and not suitable for this purpose.
I believe that almost all Socket 7 mainboards (except possibly some of the
very earliest models) are too modern.
