Thought you might care to hear if it's not already known:  NetBSD
4.0_BETA2 installs fine on a Jetway Hybrid C7 1.5G motherboard.
I've got a 512MB stick of "Samsung PC2-4200" from NCIX in it.

  Jetway Hybrid C7 JF2WE1G5D-OC-LF
  CN700 north bridge
  VT8237R+ (VT 8237RP) south bridge

I'm not sure how to read the BIOS version, but something in this
should say:

  V6.00PG

  V.J7F2WE/J7F2W A02 04-27-2006

This is my second motherboard of this model.  The first was
basically DOA.  When I returned it I saw that the folks I'd bought
it from had a stack of maybe a couple dozen returns out of a couple
hundred builds...  Anyway, _this_ one is working nicely.

I also got a 3 network adapter (rtk) daughterboard and it works
fine.  The onboard network adapter (vr) works fine.  Firewire
configures, but I haven't tested it.  The audio (auvia) configures,
but I haven't tested it.

I have an extra EPIA CN10000EG that I won't be using (long story)
and plan to return.  If anyone cares to have that tested, let me
know.

dmesg on the Jetway looks like this:
