Hi Vince.

I cut up your post and Paul's response so badly that I'll mix my comments
into what's left of these.

The 2.xx series of BDI does have some issues with these all in one boards.
I've never tried the TV stuff but the onboard graphics display will work,
even with 2.04.

Never tried this. Sounds way beyond what I want to invest. I'd swap
boards first.

I don't have a 1280 monitor here but 1024 works just fine. I've not seen
a case where the generic cyberblade driver couldn't handle this. With
2.20b I set the frame buffer memory in the bios to 2m rather than the
default 8m. I don't think the stock install handled it well so I had to
go back and use setup -> Xconfigurator. This found cyberblade just fine
but does not like most display drivers. I use custom and all of the
default values except interlaced. Non-Interlaced 1024x768 works on all
three of the Mini ITX EPIA boards that I have here.

Yes and they do not update the display as well as a dedicated graphics
card but I've not seen any degredation of EMC's motion using them here.
This is the motherboard that I used to run Cardinal's Bridgeport with
BDI-2.16 for the HSM articles. It is the same motherboard that WalMart
put in their el cheapo Lindows machines that both Joe Martin and I used
to develop the Sherline version. (We replaced the Lindows with BDI-2.18)

No 3D is required or desired. These are the kinds of display drivers that
will cause issues with the older drivers in 2.xx

With TNG, I've found that the display refresh is even slower. I use 8 bit
graphics here. You'll have to be careful how you set background color on
the desktop but the EMC stuff will work fine because it uses less than 8
bit colors.

Hope this helps
