Yes, if the image is <= 8kB. Configure your Ethernet card for a 8kB ROM
(64kbit), if not the next available size and hope for the best. There
is a discussion on this in the Ethernet HTML docs. Hope the EPROM is
fast enough; I've seen old 2764s with access times of up to 450ns. The
27C64s are usually fast enough though.
