No good waiting for an admin to manually edit a table: An admin cant edit till FreeBSD boots. FreeBSD fails to boot on some older laptops eg http://www.berklix.com/~jhs/hardware/digital/ http://www.berklix.com/~jhs/hardware/laptops/dell_latitude_xpi_p133st/ unless one pre-knows FreeBSD magic like loader.conf hw.ata.ata_dma=0 http://www.berklix.com/~jhs/hardware/laptops/#loader.conf A table in src/ that would automatically recognise flakey ATA hardware & reduce ambitious FreeBSD so it could boot, would be nice. > I've already got a sketch for this script that I use, but I'd like to ask, = > does > it worth the effort working on it a bit more, and adding it to the core OS?= > I > think this would be a quite useful feature to have.
