So I’ve had this old Dell 4100 I’ve bought from the salvation army…
Anyways, if you look at the dell page..
You’ll see clearly that the networking component is a 3com 3c905c.
Instead, thanks to an OpenBSD cd-rom I was able to find out, that it is an Intel 82562 aka 100B.
Talk about way off the mark! And at least I’ve managed to get my OS/2 2.11 backup’d and restored onto the disk..!
