The distributed code is not very good in the presence of attention messages
from the drive after reset (different drives give different messages).
>>From a shell prompt try doing "ls '#H'" a couple of times to see if it
clears any error condition on the drive.

I'm thinking we may be forced into resetting the controller but I really
don't want to do that. For instance, the controller on the Creative Labs
Vibra16 card doesn't appear to implement the necessary registers.

Hello, folks.
The good news is that as of this afternoon I finally got the three 
disk version of Plan 9 running on my system.
   The bad news is that ten minutes later the UPS guy came with the 
CD-ROM version of Plan 9. 
   I have a Mitsumi FX-400 IDE CD-ROM drive. It's attached to the 
secondary controller of an NS87410 dual-IDE controller and configured 
at 0170h and IRQ 15.
   My problem is, while attempting the CD-ROM installation, I get the 
message "ATAPI disk not found". Clearly, the Plan 9 installer isn't 
finding my drive. It's there, honest.
   Anyone have any suggestions? Like I said earlier, I've got the 
diskette version up and running, so I can tinker with configurations, 
etc.
   Thanks in advance,
   Luther Huffman, Jr.
