>I have never had any trouble with FreeBSD on IDE drives, but have >hit a snag trying to install it on a system with only a floppy and >a 3GB SCSI. It has an Adaptec 2742W and a Seagate ST43401N. >During the installation disk boot, the Adaptec is correctly probed, >but the drive is recognized as something with the wrong geometry. > >I get the following debugging message on ttyv1: >"sd0: error reading primary partition table reading fsbn 0 (sd0 >bn0; cn0 tn0 sn0)" > >The disk works perfectly under DOS and has passed a whole battery >of diagnostic tests there with flying colors. I was told to change >the labelling on the disk, but under the installation menu I'm told >I can't label it until I partition it, and the installation program >won't let me partition it because it claims I don't have a hard >drive. So how can I exit the installation menu to enter a labeling >command without forcing a reboot? And will that even solve my >problem? One note: DOS reads the logical geometry of the disk as >354 cylinders 255 sides and 63 S/T. The physical geometry is >actually 2738 cylinders and 21 sides. As far as I know only the >system BIOS is converting the geometry to LBA. Ensure that you set the proper geometry for this disk in the partition editor of the FreeBSD install. It should be, as you said above, 354/255/63 (the adaptec standard translated geometry). You can do this by hitting the 'G' key in the partition editor. >============================================= >Matt Rosenberg >Washington University School of Law >St. Louis, MO, USA > >mar7@cec.wustl.edu ; rosenbem@wulaw.wustl.edu >http://www.cec.wustl.edu/~mar7/ >============================================= > > > -- Justin T.
