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.
