MWNZ, as per
http://www.viaembedded.com/en/products/boards/1570/1/EITX-3002.html an
update is available for your BIOS (v1.04). If you update to this, does
it change anything?

If not, could you please both specify what happened, and provide the output of 
the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

** Description changed:

  I have an EPIA M910 (VX900 chipset) board with the latest BIOS (BIOS
  1.01 2012/02/17 I2100101.zip). I have a Seagate SATA ST32000542AS drive
  installed and a SATA PIONEER BDR-207D Blu-Ray burner installed for
- backups. I have no IDE devices (the IDE slots on the mobo are empty).
+ backups. I have no IDE devices (the IDE slots on the mobo are empty). In
+ the latest BIOS, the options to select SATA or IDE modes have been
+ removed. When booting into Linux, these are clearly set by the BIOS to
+ IDE mode and this cannot be changed. The kernel driver also
+ unfortunately identifies the fictitious IDE cables as 40-wire, which
+ reduces the speed from UDMA/133 to UDMA/33. This  seriously negatively
+ impacts on the usability of this machine. A selection of the relevant
+ portion of the dmesg output is appended to illustrate the problem. It
+ looks like this might be an issue in the pata_via driver. The fictitious
+ IDE "cable" should rather be detected as 80-wire to enable the UDMA/133
+ mode. Ideally, it would be useful to be able to select SATA mode through
+ a kernel option and not have to rely on that option being set in the
+ BIOS, but I am unsure of whether that would be possible. I have
+ confirmed this issue with Ubuntu 12.10 as well.
