Re: on board RAID chip

Thanks for the info. I don't actually want to use RAID, real or otherwise, on this machine. I'm more interested in just making the system recognize the two IDE channels that the "raid" chip controls, and allowing me to use them for a boot harddrive.

I've attached the complete output from lspci. However, I believe the following line is the one of interest:

0000:04:06.0 Mass storage controller: Integrated Technology Express, Inc. IT/ITE
8212 Dual channel ATA RAID controller (PCI version seems to be IT8212, embedded
seems (rev 11)

linux on google, you'll see that 95% of raid controllers are not really
raid controllers.  Certain Intel, Adataptec and 3ware are real

All the RAID chip on the mobo does (for Windows) is make it appear as a
logical volume.  You're much better off using SW RAID, there may be an
'ataraid' driver to support the BIOS' fakeraid chip, but I wouldn't
recommend it.  I'd use SW RAID1 if I were you.

Also, you may want to run lspci from command line to show us what kind of
RAID you are talking about (chipset-wise).
