And read Nick Barker's "EPIA-M-HOWTO" (might be obsolete).
Module named 'MVPSD_15.rom' is exactly the pure VGA BIOS file. Let's extract Via BIOS

+
        $ awardeco via.rom -x
+
 
+
Well, video rom size is precisely 64000 bytes. You can pad it with zeroes to 64k boundary or leave as is.
+
Just don't forget to reduce payload size at Config.lb. And read Nick Barker's "EPIA-M-HOWTO".

X-server perfomance with EPIA-M and coreboot

1) The VGA BIOS which used along with Via EPIA motherboards is located inside BIOS (Basic Input/Output System). Instead of capturing it from inside running system you can extract it from BIOS itself. Read the BIOS with

# flashrom -r via.rom

Then follow the description in VGA support

And read Nick Barker's "EPIA-M-HOWTO" (might be obsolete).

2) In order to get high resolution screen you have to grab X-drivers from unichrome.sf.net project. Otherwise the largest screen could be like this: 640x480x4 ("vga" videodriver). Unichrome drivers distributed as in binary form as well as source code. Using the latest version is more then just an advice. For instance, "unichrome_X_r20-debian_sarge_xfree86-4.3.0" appeared to work properly but had internal bugs whilst initializing "xv" video-output with MPlayer.

Essential note! Don't forget to enable "NoAccel" option in "Device" section (shown below). All other options can be used freely.

Section "Device"
    Identifier  "MyVideo"
    Driver      "via"
        # unsupported card

#    Option     "VideoRAM"              "16384"
#    Option     "UseBIOS"               "yes"
#    Option     "IgnoreEDID"            "yes"

I've done some benchmarking with x11perf command to measure X performance. All tests had been run at resolution 1024x768x16.
