(We know they're in there, but they're well-hidden.) Netboot ROMs are almost always EPROMs. In the case of a 16K netboot image, you want a 16K EPROM; one with a part number which maps well to '27128'. > A company we were referred to, LanWorks Technologies, who we > were referred to by 3Com, said that they know, but aren't about > to tell.
