A quick trip to Albatron's site proved HarOCP dead wrong. Here is what HardOCP had to say:
http://www.hardocp.com/article.html?art=MzY3LDI=
"Two Serial ATA headers are present in addition to the regular ATA133 IDE headers thanks to the Promise PDC20376 chip. Something to keep in mind is the fact that each serial ATA header supports only a single drive on each port. There is also a third IDE channel available that supports two parallel hard drives that can be used instead of the serial ATA connections. Remember, either the IDE or SATA can be used on the P4PE but not both at the same time."
This is another reason why I am losing faith in this website. (in addition to the Hyper-threading snafu). They are dead wrong on two counts. The Parallel ATA channel only supports one drive, and you CAN use Parallel and Serial ATA together (although I can't imagine why anyone would do this). I find quite alarming how easily they can pass off two false facts as truthful, when the answer was probably right there in the manual!
Here is what Albatron says about the Promise Controller:
Promise Disk Management
Specialized Disk Management system providing RAID (level 0,1) functionality.
Promise HDD Connectors
One Parallel ATA 133 connector supporting one hard drive. Two Serial ATA 150 connectors each supporting one hard drive.
Promise RAID Options
RAID 0 - striped array using one to three Promise drives (one Parallel, two Serial).
RAID 1 - mirrored array using any two Promise drives (Serial/Parallel or Serial/Serial).
GraveLayer, this new bios revision sounds promising. I was reading in another forum that Watch-Dog timer was really screwing up everbody's overclocks over default voltage.
I really want to try a PE board with the 3:4 memory ratio, but I don't think it's worth sacrificing RAID to get it!
