My setup was a HP 660MB Drive with a BusLogic (adaptec 1542 compatible). I already had installed does and OS-BS (Excellent program!!) and proceded to install FreeBSD on the rest of the drive. After installing the kernel and trying to boot, I got the Missing OS error. Solution (for me at least): FreeBSD's disk parameters were not the same as DOS (Free BSD reported 1647 cyl's whereas DOS thinks there are 645 cyls). So, using my linux boot disk (yes, I also use linux :-), I got the correct disk info and fed that to the FreeBSD install program and everything worked like a peach after that! This is mentioned in the FAQ/Install_Notes somewhere but I don't understand why FreeBSD gets different disk parameters vs. Dos or Linux. Anyway, the bottom line is check to make sure FreeBSD is using the same disk params/geometry as DOS. Hope this works for you. mahesh
