Sounds like an excellent idea, but unfortunately, it has not worked in practice for me. I have a Gigabyte DS3 motherboard with an E6300 cpu. There is only one IDE connector (two IDE devices) on this motherboard. If I plug in a PCI IDE controller with a Silicon Image chipset, the motherboard will not boot -- it posts, but will never start the boot. It will boot with a Promise IDE card, but we all know that Promise does not handle optical drives, only hard drives.
I have tried three different Silicon Image cards with the same results. On one of them, I had even blanked the BIOS.
I have a Liteon 16A7S SATA, and it is working perfectly. When the Pioneer 212 becomes available here in the States, I intend to purchase one and try it out.
ON EDIT: On rereading this post, I see the need for clarification. The setup is booting from a SATA hard drive. I insert a PCI card with a Silicon Image chipset (no drive attached), and power up. The motherboard posts, but never starts to look for a boot device (CD, hard drive, anything). It just hangs on the POST screen.
