I did configure my kernel properly now.
Part of the verbose boot:
1042MB (2134305 512 byte sectors)
sd1(ncr0:6:0): with 3835 cyls, 4 heads, and an average 139 sectors/track
pci0:10: vendor=0x1050, device=0x0940, class=network (ethernet) int a irq 11
[no driver assigned]
map(10): io(ff40)
pci0: uses 67109120 bytes of memory from f8000000 upto ffbdffff.
pci0: uses 272 bytes of I/O space from fc00 upto ffff.
Probing for devices on the ISA bus:
In pci/ed*.c (forgot the exact name) I saw that a match is done for
PCI NE2000 clones on some 'type' value to be 0x802910ec. (Vendor
10ec.). I changed this match to 0x09401050. Result: the card is
'recognized' as ed2 (ed0,1 were in the config file) but immediately I
get a crash :-(
The linux kernel does probe it, but only after a special patch to the
latest stable kernel. From dmesg on Linux:
ne.c: PCI BIOS reports Winbond NE2000-PCI at i/o 0xff40, irq 11.
ne.c:v1.10 9/23/94 Donald Becker (becker@cesdis.gsfc.nasa.gov)
NE*000 ethercard probe at 0xff40: 00 40 95 00 57 83
eth0: NE2000 found at 0xff40, using IRQ 11.
The strange thing is that Winbond vendor is 0x10ad, and the device ID
is 0x0105 (instead of vendor 1050 and device 0940 as seen for pci0:10
on FreeBSD).
I hope someone can help me to get my NE2000 PCI clone to work under
FreeBSD.
