Running OpenBSD 2.7 (and later) apm mostly works. To

get "halt -p" to work, you must set the sysctl variable

machdep.apmhalt to 1 (you need OpenBSD 2.8-current with

sources from mid-January, or later). The unit goes into

suspend mode when top is closed. Restores nicely

when top opened.

Built in modem is a winmodem... ignore it. Actually it is on

a `mini-pci' card so it can probably be removed.

Audio works, but you have to turn off PCI sleep mode in the BIOS.

OpenBSD X11 supports this machine as of 2.8, but there is lots

of visual noise at 32bpp. Image is fine at 16 bpp. XF4 config

file for OpenBSD 2.9 can be found
