ICH5R SATA RAID?

[Mike Jakubik]

Hello,

I recently purchased a Supermicro Intel P4 MB w/ 875P chipset (p4sce) with
the assumption/hope that serial ata raid would function. However this does
not seem so. After managing to install FreeBSD on a pata drive (the
bootloader would crash if I used a cd to install when serial controller
was enabled, had to use a floppy) and updating to latest –current code,
the raid controller is not recognized. This is what dmseg displays:

atapci0: <Intel ICH5 UDMA100 controller> port
0xf000-0xf00f,0-0x3,0-0x7,0-0x3,0-0x7 at device 31.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
pci0: <mass storage, RAID> at device 31.2 (no driver attached)

Is ICH5R not supported? Am I doing something wrong?

FYI: The plain serial ata works.

Thanks.
