Hello! I've bought a Promise FastTrak TX4310 because I thought that it will be supported by FreeBSD's ata/ar driver...: http://www.freebsd.org/cgi/man.cgi?query=ata&apropos=0&sektion=0&manpath=FreeBSD+6.0-stable&format=html I've updated the controller's BIOS to the newest available v2.5.1.3116: http://www.promise.com/support/download/download2_eng.asp?productID=165&category=all&os=100 And there are two Seagate ST3300622AS connected to the controller with RAID0. But if I boot from a 6.1-RELEASE-i386-disc then I only get an ad6 and an ad10 device and no arX device... :-((( So I can't use them in RAID0 mode... Can anyone of you help me? Best regards, Lukas
