To answer my own question : yes, it is. 'c' should be the FreeBSD area of the disk, 'd' should be the whole disk. Also, something the manual page misses out on : Normally, the first 32 sectors of a disk are unused, it says. In fact, if you have more than 32 sectors on a cylinder, that number is the unused value - so that if you're running a drive in 63-sector translation mode, the offset value for the to-be-dos partition is the number of sectors per track, ie 63. >-- ># mike smith : miff@apanix.apana.org.au - Silicon grease monkey # ># "The question 'why are the fundamental laws of nature mathematical' # ># then invites the trivial response 'because we define as fundamental # ># those laws which are mathematical'".
