FreeBSD was installed when the machine had only the internal controller & saw it as ahc1. Now that the secondary controller has been added, it sees it as ahc0, gets the disks off it 1st and fails when it attempts to mount root of the first disk on the ahc0 chain. All would be hunky dory if I could disable ahc0 from the boot prompt or automagically change which disk it looks at for its root partition. I can't pull the controller out, not even temporarily (its prime purpose in life is to run UnixWare & Ingres for a largish DB). It's a box with dual 166MHz pentiums, 128Mb of memory & 7 x 2Gb disks, so you can understand why I'm rather keen to give FreeBSD a good workout, plus run the rather well-known game quake^H^H^H^H^H^H video tester at high resolutions. Anyone have any ideas? Stephen -- The views expressed above are not those of the Worker's Compensation Board of Queensland, Australia.
