iy0 at isa? port {port} irq ?
The iy device driver supports the EtherExpress PRO/10
  card, and might support other ISA cards using the same chip.
The different models of the supported boards come with some subset of RJ-45, BNC
  and AUI connectors. Supported media include:
  - AUI/DIX
- Standard 15 pin connector
- 10Base2
- BNC, also known as thin-net
- 10BaseT
- UTP, also known as twisted pair
 
The default port to use is the port the card autodetects at
    ifconfig up time. To choose an alternative port, an
    explicit medium can be specified to
    ifconfig(8) or in your
    ifconfig.iy? file.
The EtherExpress PRO card has no jumpers to set the address. Intel supplies
  software to set the address of the card in software. You have to hardwire this
  address in your kernel configuration file.
are great. There's so many to choose from.
