works ok, with T9300 cpus.
* Onboard ATA/CF controller not supported by ESXi4.0.
* Onboard ATA interface share channel with CF slot, CF is set to master.
Installed ESX 4i via pxe to SATA disks (ich9m) , and got two of these boxes running.
Onboard SATA (ich9m) and both gigabit lan (e1000) works properly.
