OT: Effective Speed of 10BaseT

Actually, I was wondering something similar myself :) I've got two old VAXstation 2000's that i've been trying to netboot and neither one of them are cooperating much.. They've both got lance boards that check out alright with the ROM diags ("t 0"), link up fine (link light on transciever and hub on), but when I try and netboot NetBSD on them, I get strange %VMB-F-ERR type messages and it bombs out... I tried pulling the box apart for inspection; the board looks like its OK.. I found a jumper on the lance board and tried moving it to the other position, but it didnt do anything toward resolving the problem. I get the same error with two different VAXstation 2000 systems, both with lance boards that check out OK in ROM diags.. Is there something I should know about configuring these little buggers or have both the boards died in some strange way? I'd appreciate any pointers anybody could give me on them!
