Hi List, Maybe this has been already discussed but it is very important for me. I will be setting up a 4.9 server these days on a motherboard with Serial ATA controllers and with Serial ATA discs. I was reading about the support of Serial ATA in 4.x but could not find a clear answer if my motherboard controllers are supported under FreeBSD. The motherboard is: Asus P4 P800-VM Intel 865G 800FSB/4GB and the discs are Seagate 80GB Serial ATA 8MB cache. Is this hardware going to work under FreeBSD 4.9-STABLE in Serial ATA mode? I am even more confused about this serial ata 'support' because www.serialata.com says that it is supposed to be transparent to the OS! Another question I have is: The motherboard has 2 UltraATA 100 controllers which can be used (if serial ata controllers are not supported) with serial ata discs with the aid of a convertor (PATA to SATA). Are these UltraATA 100 controllers supported? Has anyone set up that kind of configuration under FreeBSD 4.x(9) ? I would appreciate all your comments. Thank you in advance. Rumen Telbizov
