>Organization:
The NetBSD Project
>Environment:
FreeBSD 4.6.2-RELEASE FreeBSD 4.6.2-RELEASE #0: Wed Aug 14 21:23:26 GMT 2002 murray@builder.freebsdmall.com:/usr/src/sys/compile/GENERIC i386
>Description:
FreeBSD 4.6.2 boots from CD-ROM and installs happily on this beast, but the built-in Ethernet (a SiS 900) does not work. The system description can be found here:

http://www3pub.amd.com/products/cpg/easynow/prodbrief.html

This system is "legacy-free" (i.e. no serial ports, no parallel port, no PC keyboard/mouse controller; that all is the province of USB). It also has no expansion slots, so adding in a supported PCI card is not poissible. Aside from the AMD K6-2, this system is built pretty much entirely of SiS support chips.
>How-To-Repeat:
Boot FreeBSD 4.6.2 GENERIC on the box. Observe:

sis0: <SiS 900 10/100baseTX> port 0xe400-0xe4ff mem 0xdd901000-0xxx901fff irq 11 at device 1.1 on pci0
sis0: Ethernet address: 00:30:67:03:3f:19
sis0: MII without any PHY!
device_probe_and_attach: sis0 attach returned 6

observe that neither ifconfig nor netstat -i see the device once single user mode is achieved.
