Hi: I have a similar problem. A PCI/EISA combo bus on a Dell Omniplex 466, houses an NCR 53C810 SCSI controller, and a 3c509 is sitting on the EISA. The freebsd 2.1.0 boot doesnt recognise the 3c509 sitting on the EISA bus of the PCI/EISA combo, though it does recognise the NCR and the SCSI disk on it. Any help/advice/suggestions will be appreciated. thanks rv -- using MH template repl.format -- In a previous message, Stefan Esser writes: > On Jan 25, 23:16, pieter van der steen wrote: > } Subject: FreeBSD doesnt see NCR 53C810 SCSI controller > } Subject: FreeBSD does not recognize NCR 53C810 SCSI controller > } > } I tried to install FreeBSD 2.0.5.
