Hello Everyone, I found that on the newer IBM 4500R the AMD ethernet chipset version is an new version(which 'Am79C975'). The newer version does not have a freebsd driver. I did some investgation and found that in Linux the new driver didn't seem to do anything different from the previous version. (it had set the same vars, it just handled detecting of the new chipset version and setting the new chipset name.) But I didn't try to hack the driver in FreeBSD because I still don't understand the structure and what the driver does well enough. It seems that it could be added in, '/usr/src/sys/i386/isa/if_lnc.c' and in the header '/usr/src/sys/i386/isa/if_lnc.h' as a new 'Chip Type'. Any helpful hints, links to FreeBSD device drivers how tos, etc? The other thing that seems odd to me is that these drivers still live under ISA and not under the PCI tree, it doesn't seem to matter but I was wondering why.
