Hi,
        Anybody know why I'm not getting 160MB transfers ?
        Kernel is Suse 2.4.19
        MB is Intel D845PESVL + 2.4 P4 + 512MB DDR333 ram.
        Adaptec card is in 3rd PCI slot.
        AGP ATI 7500 vga
        2 x U160 disks on channel B with special U160 cable and actively
        terminated.
        DVD + DAT on SE channel A. Nothing on U160 channel A.
        Snips under from log and /proc
        Thanks
        Margit Schubert-While
