CCR_PCMCIA	If set, this is a PCMCIA bus. Otherwise, it is an ISA bus.
CCR_AUI	If set, the attachment unit interface (AUI) is available.
CCR_10B2	If set, the 10Base2 receiver is available.
CCR_ENDEC	If set, the internal encode/decode (ENDEC)
	loopback is used.
CCR_RESET	Reset adapter.
CCR_ENA	Enable adapter.

ACR_10BT	If set, the information transmission rate is at
	10 Mb/sec for the Ethernet unshielded
	twisted-pair cable wires.
ACR_10B5	If set, the information transmission rate is at
	10 Mb/sec for the Ethernet thick coaxial cable wire.
	The length between repeaters is 500 meters.
ACR_10B2	If set, the information transmission rate is at 10
	Mb/sec for the Ethernet thin coaxial cable wire. The
	length between repeaters is 200 meters.
ACR_ROMS	Represents the read-only memory size for the ISA bus.
ACR_ROMB	Represents the read-only memory base for the ISA bus.
ACR_ASE	Represents the autoselect mode.
