Hello Kai, Have you looked at the options in the BIOS setup utility (RBSU)? There should be an option to select the boot controller (which should be the P400 in your case). If that is already set to the P400, then the problem may be one of PCI enumeration. If FreeBSD loads the mpt driver first, then it may grab da0. Maybe there's a way to force it to load the ciss driver first?
