Hopefully when this is released there will be some hard and fast definition
of "large" (unlike the confusion many years ago with a similar supplement
for 5.0.2), and whether installing it on a "not large" system will have any
adverse effects.

Thanks for the detailed information. I wish/hope that these details will be
included in the various README files on the SCO Openserver ftp site,
which haven't been properly updated in weeks. Specifically, there's no
indication which SLS and driver files are already included in or
superceded by MP1 & UP1. A TA summarizing the installation order that
you posted earlier is probably also warranted.
