It's an IDE translation, btw. Anyway, you've been missing my point. In one occasion, sysinstall errouneously prevented me from using the inner partition as root, even though it would have been possible. In another case, it didn't tell me anything, but i finally got stuck with an unusable root file system, since it was in the second FreeBSD slice, and sysinstall attempted to newfs in the `compatibility' slice (which is the same the boot loader would use). I guess the above is totally unrelated to the magic 1024 cylinder number, sysinstall _intents_ to be smart about the problems with the compat slice, but it's got it wrong (decision being made based on the location of the data cylinders on the disk, instead of based on the fdisk slot # as it ought to be -- remember, the compat slice it the first FreeBSD slice as seen in the fdisk table). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
