Even if it is now the only advantage, it is still one hell of a big one. Until recently I'd 6 disks, 2 streamer/DAT and one CD-ROM on 2 controllers with still 5 ID to put things on. Now I removed 2 small disks to make some room after putting my ASUS PCI-875 in place... ncr0: T:L Vendor Device Rev Speed Max Wide Tags 0:0 IBM DCAS-34330W S65A 200.0 20.0 16 8 2:0 IBM DORS-32160 WA6A 200.0 20.0 8 8 4:0 TANDBERG TDC 3600 =08: ? 20.0 ? - ncr1: T:L Vendor Device Rev Speed Max Wide Tags 1:0 MICROP 1624-07MZ1077801 HZ2P 100.0 10.0 8 8 2:0 CONNER CFP1080S 3939 100.0 10.0 8 8 5:0 HP HP35480A 1009 50.0 10.0 8 - 6:0 MATSHITA CD-ROM CR-8004 1.1f 19.0 10.0 8 - > But then again you have to pay solid bucks to get that :) At 80 US$ for a SC-200 (NCR-810) and 140 US$ for a PCI-875 Ultra Wide card (in France), that's not too hard. The IDE disks are cheaper that's right but still won't allow crappy interfaces anywhere near my machine :-) -- Ollivier ROBERT -=- FreeBSD: There are no limits -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 3.0-CURRENT #29: Tue Aug 26 21:05:09 CEST 1997
