On my machine n3lxx, my FreeBSD installation is the first partition on the disk, and I mount the dos partition with: mount -t msdos /dev/sd0s1 /dos On my other (older) machine, dos is in the third of 4 partitions, so to do the same mount, I issue: mount -t msdos /dev/sd0s3 /dos When I want to refer to one of the BSD partitions, say what you name sd0a above, and on n3lxx its on the 2nd slot of the partition, I refer to /dev/sd0s2a. This means first (zeroth) disk, second partition slot (this number isn't 0 based, to better confuse you), and the 'a' BSD partition. Just to make things real clear, the machine's partition table holds only 4 partitions, so if you go looking in /dev, you'll only see entries for sd0s1, sd0s2, sd0s3, and sd0s4. Probably only your FreeBSD partition will have the BSD devices like sd0s2a. ============================================================================ Chuck Robey chuckr@eng.umd.edu -- I run FreeBSD on n3lxx and Journey2 --------------------------------------------------------------------------- The Dilbert Zone is Dilbert's new WWW home!
