The change occurred when Intel decided that Project UDI would be
a good idea for Intel-based UNIX servers. Please read the below
URL.

Below is a brief quote from this URL

<Begin Quote>
Rattner was talking during the week that Intel announced its
decision to support Project UDI (Uniform Driver Interface),
a Unix industry initiative to develop a single device driver
implementation that will work across different Unix operating
systems running on Intel platforms. Project UDI is made up of
representatives from Compaq, Hewlett-Packard, IBM, SCO and Sun
as well as Adaptec, Bit3 and Interphase. Intel is to provide
information on interfaces and initiatives as well as engineering
resources to help complete a reference design. The complete
specification is due to be delivered at the next Intel Developer
Forum in February.

Please note who is writing the reference platform: Intel
Please note what Rattner stated in the very first line:
"to develop a single device driver implementation that will
work across different UNIX operatiog systems running on
Intel platform."

Granted the proof-of-concept was cross platform.
Please refer to http://www.sco.com.udi, with Intel entering
to the picture is would appear that cross platform has been
replaced with Intel specific.
