System: NetBSD guava.araneus.fi 1.1 NetBSD 1.1 (GUAVA) #3: Wed Feb 28 12:27:14 EET 1996 gson@guava.araneus.fi:/usr/src/sys/arch/i386/compile/GUAVA i386

>Description:

There is no way to configure a "uk" (generic SCSI) device in
NetBSD/i386, despite the fact that the driver itself already
exists and is fully functional.

I submitted a set of patches correcting the situation as PR #988
as early as April, 1995.  Regrettably, these changes have not been
integrated into NetBSD 1.1.  Since then, there have been extensive
changes to the configuration mechanisms, necessitating a revised set
of patches (enclosed).

I have now been using the "uk" driver successfully for almost a year,
driving a Sharp JX-300 GPIB flatbed scanner through a National
Instruments SCSI/GPIB interface unit.

>How-To-Repeat:

Attempt to configure a "uk" device on a NetBSD/i386 system.

>Fix:

Apply the following patches.
