31.Sh NAME
32.Nm cs
33.Nd ethernet device driver
34.Sh SYNOPSIS
35.Cd "device cs"
36.Pp
37In
38.Pa /boot/device.hints :
39.Cd hint.cs.0.at="isa"
40.Cd hint.cs.0.port="0x300"
41.Cd hint.cs.0.irq="10"
42.Cd hint.cs.0.maddr="0xd000"
43.Sh DESCRIPTION
44The
45.Nm
46driver provides support for ISA ethernet adapters based on the
47.Tn Crystal Semiconductor CS8900
48and
49.Tn CS8920
50NICs. These devices are used on the
51.Tn IBM EtherJet ISA
52adapters and in many embedded applications where the high integration, small
53size and low cost of the CS89x0 family compensate for their drawbacks.
54.Pp
55The
56.Nm
57driver will obtain configuration parameters either from
58.Pa /boot/device.hints
59or from the card.
60At least the I/O port number must be specified.
61Other parameters specified in
62.Pa /boot/device.hints
63will be used if present;
64the card may be soft-configured so these may be any valid
65value. Adapters based on the CS8920 normally offer PnP configuration and the driver
66will detect the
67.Tn IBM EtherJet
68and the
69.Tn CSC6040
70adapters automatically.
71.Pp
72Note that the CS8900 is limited to 4 IRQ values; these are normally implemented
