Sir, i have an msi n1996 (vt8237r & km400 8237) mother board. My sata 160 gb hdd is not getting recognized in bios. Pl. help. (it is reported somewhare on the net that i have to enter into the raid configuration of the motherboard before booting windows and after bios post to get the sata disks recognized.) Thanks in advance. bvrm

I enabled SATA support on my BioStar M7VIZ-SATA MOBO (it is km400 and 8237r, like yours) by first installing the VIA SATA RAID drivers. At this point, Windows recognized the device controller but not the 120GB drive. The problem was that the system doesn't support "newer" SATA drives, so I installed a jumper on the disk drive to set it to "150" mode... SATA version 1 compatibility. After that, Windows immediately recognized the drive and mounted the filesystem.

I think it was a Western Digital drive. Other manufacturers have a different name for the same jumper. Also, I read that one type (Samsung?) can only be set to the old SATA standard by getting the drive running in a SATA 2 environment, then using a utility program to adjust the drive's microcode setting.

Good Luck to you.

Try to change your hard disk jumper into master position
