The real problem here is that I cannot just use the latest ATA specs (it would make my life *alot* simpler though :) ), I need to make things work that are compatible to at least back to ATA rev3 so just relying on things be obsoleted in the latest spec revision doesn't cut it.. > Code I submitted was to make ata driver more verbose about CHS mode. > They still are not there and should be revised to make them possible to > apply to current code. I'll think about it, but since CHS mode is almost no longer used anyways and the info can pretty easily be calculated from the LBA's printed.. > By the way, may be it would be a nice idea to warn users that they have > ATA_FLAG_54_58 bit off, and device will work in LBA mode not > in CHS as was before? Users wont notice at all, from users perspective the disk is just a bunch of sectors, the interface method used to talk to the disk is nowhere to be seen... -- -Søren
