It doesn't matter what restrictions or capabilities existed on the X side of an X-to-ATA/ATAPI bridge. The bridge must follow the ATA/ATAPI protocols on the ATA side and I assume it should follow the X protocols on the X side. Of course that means snooping commands and command parameters, buffering data so that things like the X packet protocols are not violated, etc. When someone or some company takes on the task of designing an X-to-Y bridge they have the responsibility to fully understand both X and Y and make sure your bridge works properly on both X and Y interfaces. ===================END FORWARDED MESSAGE=================== *** Hale Landis *** [EMAIL PROTECTED] *** *** Niwot, CO USA *** www.ata-atapi.com *** Subscribe/Unsubscribe instructions can be found at www.t13.org.
