They work and are hooked up to a bunch of IBM 9gb sca drives. Currently the first card boots gentoo or something (someone gave me the box; I don't have the root password so I haven't booted past the linux loader/grub/whatever). /stand/sysinstall sees all the drives fine. The cards actually are very forward-thinking, with a row of 15 blinkenlights reminiscent of Knight Rider, a design which has since firmly incorporated itself into the current bling-bling hardware. I know these cards are old, but fbsd supports them and I don't want to waste the drives on this rig. Also want to take a chance to play with RAID for free(tm). Hence the cc to freebsd-hackers. > > > On Wed, 16 Feb 2005 01:57:00 -0500, Peter C.
