I do not think that would work. These IDE RAID use a slightly different layout that someone would expect. This means that you cannot map it 1:1 to any RAID personality, therefore you cannot boot from it. (Free)BSD supports this IDE RAID controller with the RAID functionality. Maybe you want to check it out. I want to write a kernel module for 2.4 which supports the HPT370 RAID. You can be sure that I will peek at the FreeBSD code. In fact that is the only documentation I have. Wilfried
