But I was reusing a disk which had been in a Linux box before, not BSDI. (And I seem to remember also having the same problem a long time ago with an earlier FreeBSD, and I think it might also have been an ex-Linux disk.) > This is on pretty standard IDE-only hardware.

Not even that worked for me. :-( Check the drive geomoetry as reported by the BIOS. Then check the geometry as reported by the FreeBSD kernel while the floppy boots. If they differ, then see if you can set the BIOS's view of the drive geometry to suit FreeBSD's. Also, when using sysinstall, use 'G' while disklabeling to set the geometry to the same values. I assume that most of these problems are due to the BIOS geometry translations, and different things ending up believing different geometries. -- V Johann Visagie | Email: wjv@CityIP.co.za | Tel: +27 21 419-7878 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
