>Environment:
Intel DG965WH main board . Installation is NOT possible , therefore , there is 
NO "uname -a" . Memory : 6 GB . HDD : SATA 250 GB . Processor : Intel E2220 .
>Description:
The Intel DG965WH main board has , in its BIOS , settings for hard disks only 
RAID mode or IDE mode .
In IDE mode , SATA disks are NOT detected . They are detected in RAID mode .
When NetBSD is attempted to be installed , it is detecting the hard disk 
correctly , but during install , after destroying boot sector and possibly 
partition tables , etc. , it is given an error about failure and abandoning the 
install leaving a non-bootable hard disk because previous operating system is 
overwritten without any useful part from NetBSD .

This behavior is ONLY performed by the NetBSD . OpenBSD , decided NOT to 
install on RAID mode without considering number of disks ( when there is ONE 
disk , there is NO RAID ) .

The other operating systems ( from Windows 7 to any Linux , FreeBSD , etc. ) 
are installing fine on that configuration .


>How-To-Repeat:

It may be tested in a similar mainboard , or perhaps a RAID card with single 
disk .

>Fix:

Other operating systems are successfully installing on such a main board ( RAID 
mode , single disk ) . I did NOT test RAID mode , multiple disks , and I did 
NOT make such an install .
