The Good:
I am VERY pleased with this board. Yeah I am still tweaking it in the car, mostly because of other new stuff, but wow what a difference in speed and capability vs. the old tried and true MII 10000. I could never run VIS now I can with only 38%-45% CPU usage (G-Force vis).
Flash is now an option, just running Road Runner it sits at a nice 20% Usage. The screens are almost instant, much more responsive. The devices seem to be more responsive as well, much faster - once the system is up and running (boot up time is slightly slower).
Power usage is extremely low.
The Bad:
The other side of things, some USB devices are a handful getting them to boot and hold drivers properly. I called Opus on this perhaps an over usage of the 5v rail, but Opus said "no way" They too are very impressed by the Little Valley board.
The drive home, all the devices held so perhaps its fixed
Bios is very simplistic, need more options. I did not find a setting for LCD/CRT in the bios for example, perhaps there is one but did not see one on Intel's website from the bios glossary.
The 800x480 capability is there, however you can not "tweak the width or height" Therefore I am running into issues where the desktop/Road Runner etc. is too wide on the 7" lilli. All I am left with right now is the settings on the monitor itself which is maxed out so it still needs to shrink, there should be settings for the SIS on board graphics for the simple things like width and height of the desktop. There maybe one, but I have yet to find it.
S3 or lack there of, well its not a big issue for me as I always turn my computer off.
USB Headers, will get back to you on this one, pluged a USB 2.0 Engenius Wifi adapter into it and only read it as a 1.0 device and would not work at all. The USB's on the back are reading as 2.0 and the Engenius worked "sort of fine" there. I installed a 4 port USB PCI card until I see what is up with the headers, I have ordered replacement header connectors to make sure its not that. It could also be a Bios setting, if it is they should set it up for 2.0 as default.
Getting cold here nights are -3 or so C. The real test will be in 2-3 months where its -30. So far no issues on temps.
I can not comment on the sound as I use an Audigy 2 NX.
For 70 bucks, incredibly pleased, I will never spend 3x the cost just for an EPIA VIA mobo again, there is no reason for it. The issues are very minor, there is always something that needs to be tweaked anyway. This board is probably the best thing I have ever purchased as far as price/performance for a car computer.
Lets hope one day someone makes a VGA LCD monitor with the same price/performance quality.
