I'm not sure about the 1522, but if it allows for ``DOS > 1 GB'' translation (63 sectors per virtual track, 256 virtual heads), it should also work with the AHA2940. Btw., if the disk is installed in ``dangerously dedicated'' mode (*), the actual translation shouldn't matter at all. (*) That's what you get by saying ``A)ll FreeBSD'' in the partition editor, but answering the next question about remaining compatible with other operating systems with ``No'', regardless of how many nasty dragons you're being promised. ;-) Basically, it drops BSD on your disk starting straight at sector 0, so the BSD bootstrap acts as the master boot record. The only geometry assumption in this mode is that your translation allows for at least 15 sectors in a single track (the size of the bootstrap itself). -- 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. ;-)
