If you can convince your BIOS that it uses a translation scheme where this ``> 600 MB'' leaves at least 20 MB below the fictitious 1024 cylinder mark, you can do it. Only the FreeBSD root partition (partition `a' inside the FreeBSD slice) must be reachable from within the BIOS. Many SCSI controllers translate their disks to 1 MB per fictitious cylinder. This would require the FreeBSD slice of the disk to start below 980 MB. Many IDE BIOSes translate their disks to 504 KB per fictitious cylinder. This would require the FreeBSD slice to start below ~ 484 MB. (Wonder why i'm always writing ``fictitious''? You never know the real geometry of a modern disk, and besides, this one is totally unimportant.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
