I spend most of my time supporting Sun hardware but I find myself having to 
deal with a little Apollo stuff.  In the Sun (& HP9000) arena, it's possible 
to connect just about any 3rd party SCSI disk.  last week I tried to connect a 
HP-97548E to a DN3500.  The unit eventuly complained that the drive type was 
unrecognized.  I have heard from usually reliable sources that Apollo 
likes to read MFG codes from disks, boards, etc, and lock out
anything that they didn't sell.  I'd appreciate it if someone out there
could confirm/deny this.  If they are low enough to really do this has anyone
determined where to patch their verification routines or tables to replace
one of their entries with one of my choosing?   I hope Apollo users really
aren't trapped to Apollo's repackaged peripherals.   

Please respond by mail and I'll Summarize to the net.

Regards

Dan
