Hello Roger,
I have two SMC ISA NICs running in a 486 under FreeBSD 3.5-STABLE. The
chip number is only slightly different: SMC, UltraChip, 83C790QF, C9451,
6M61627-4.
The I/O and memory window address on my cards are jumper selectable.
My kernel configuration lines are as follows:
#
# SMC UltraChip 10-Base-T ISA
#
device ed0 at isa? port 0x280 net irq 3 iomem 0xd0000
device ed1 at isa? port 0x300 net irq 10 iomem 0xcc000
Edited dmesg output:
ed0 at 0x280-0x29f irq 3 maddr 0xd0000 msize 16384 on isa
ed0: address 00:00:00:00:00:00, type SMC8216T (16 bit)
ed1 at 0x300-0x31f irq 10 maddr 0xcc000 msize 16384 on isa
ed1: address 00:00:00:00:00:00, type SMC8216T (16 bit)
The source code for ed ethernet driver (/usr/src/sys/i386/isa/if_ed.c)
mentions the SMC 8216C:
case ED_TYPE_SMC8216C: /* 8216 has 16K shared mem -- 8416 has 8K */
case ED_TYPE_SMC8216T:
if (sc->type == ED_TYPE_SMC8216C) {
sc->type_str = "SMC8216/SMC8216C";
} else {
sc->type_str = "SMC8216T";
}
Good luck,
Aaron
