Specifically, the lnc driver declares NLNC softcs. Mark has an isa style ``device lnc0'' in his config and then uses vmware with two configured devices. Actually, PCI cards allocated their own softc dynamically, only ISA cards accessed the softc array. config kernel produces lnc.h which contains ``#define NLNC 1'' and if_lnc_pci.c dives in and starts writing to the second softc. I'll look at fixing this at some point if you don't have time Paul :-I Just got back from the Perl cruise, still catching up with things. This may have broken because Paul changed the softc decl from static to just global (so that the other if_lnc*.c modules can get at it) either that or Mark has been ``just lucky'' so far and the lnc driver has never worked properly with more than one device. This would neatly It was working with more than one device (one PCI and one ISA) the day I left, which was 19 May. I think the changes to the PCI and ISA compatibility code modified something relating to unit number allocation that caused the ISA driver to get a unit number NLNC whereas before the ISA instances would come first and the PCI instances would get unit numbers after the ISA cards, since the PCI part of the driver creates softc structures dynamically that worked fine.

This would neatly explain why he's seen funny errors in the past - one of them was a message to you Garrett saying that your npx.c modification to do no more than output a boot-time diagnostic seemed to screw up his kernel !!! -- Mark Knight PGP Public Key: finger [EMAIL PROTECTED] -- Brian [EMAIL PROTECTED]brian@[uk.]FreeBSD.org http://www.Awfulhak.org brian@[uk.]OpenBSD.org Don't _EVER_ lose your sense of humour !
