>Description:
	The AMD EasyNow! PC is a "legacy-free", integrated system
	based around an SiS motherboard.

	The major chips are the SiS 530 and SiS 960.

	One DIMM slot for PC100 RAM, maximum 128 megabytes.

	No PCI slots - all system expansion is done with USB.

	Available I/O devices are: one IDE disk, one IDE/ATAPI
	CD-ROM drive, a "winmodem" line interface (two RJ-11's,
	one marked for line, one for phone), four sound jacks (mic
	in, line in, headphones out, line out), an HD-15 VGA, five
	USB ports, and an RJ-45 for 10/100 Ethernet.

	The sip driver attaches to the SiS 900 core found on the
	internal PCI bus, but scans of the MII bus find no PHYs
	(bsmr for all PHY id's come back as 0xffff). According to
	the system manual, this computer supports both standard
	10/100 Ethernet through its RJ-45 jack, and HomePNA through
	the RJ-11 line interface, using an AMD 79c901 PHY (seen on
	the motherboard), so there must be at least two PHYs on
	the MII (or somewhere).

	NetBSD was installed on this system by preparing an IDE
	disk on another i386 system, and physically installing that
	disk in this system.

	I'd like to get the 10/100 Ethernet interface to work properly.
