The USB legacy support for keyboards is probably not a problem for you
with the DVD problem.
The only BIOS items that I adjusted on a Dell computer were related to
the video, so I did not look for USB related items.
So you are experiencing a massive degeneration in performance when the
dvd is set as an ATAPI (hdx) but not when it is recognized as an SCSI
(sdx) device?
Sorry for the off-topic lead.
