Hi Steve,

        I have an FIC PA2007 mobo with the VIA Apollo2 chipset. This chipset
supports UDMA. I have a WD Caviar 2.1 GB EIDE installed as a master on the
first IDE channel and a WD 3.2 GB UDMA installed as the slave on the first
IDE channel. When my computer boots, it shows the 2.1 GB as PIO mode 4 and
the 3.2 GB as UDMA mode 2. I am not sure if I am getting UDMA performance,
however because I think the EIDE drive on the same channel limits the UDMA
drive. I also do not have the bus mastering drivers installed.

FWIW
