System: NetBSD hideo 1.3H NetBSD 1.3H (HIDEO) #19: Tue Sep 29 15:07:29 MDT 1998 root@hideo:/usr/src/sys/arch/i386/compile/HIDEO i386


>Description:
I've got a CDL-1100, which is a Sony CD-ROM jukebox.  Using a normal
kernel, it doesn't work.  This appears to be a result of block
descriptors being disabled in the ch(4) driver.
>How-To-Repeat:
See above, and message posted to current-users.
>Fix:
This patch makes the device work with my setup.  However, it's
obviously a hack.  There should be a better way to do this, but I
don't know how.

 Just saw this old PR of mine.

 I no longer have access to the hardware in question.  The current admin 
 should be reachable at <root@nervana.montana.edu>.

State-Changed-Why:  
The submitter no longer has the equipment in question, so it appears 
Jason either has to apply a patch blind (which might not be so bad) 
or the PR has to get closed.

 Mike Hitch may be able to get access to the equipment.  If it still 
 exists, I can probably tell him where it is.
