Now I have upgraded the machine to a 200MHz Pentium Pro and I am getting "st0(ncr0:5:0): COMMAND FAILED (4 88) @f112ce00." messages when using the tape. It will work for a while and then give this error at random places. I am still using the exact same controller and cable and the jukebox is in an external box. It is the only device on that SCSI bus and it is terminated on the controller and at the end of the cable. I had a look at the status codes and the 4 seems to indicate that the host was finished, but the 88 does not seem to exist in the S_xxxxx status codes or can you OR the bits? Is it possible that there is a timing problem in the driver somewhere? Have someone else came across this problem with a solution maybe? Thanks John -- John Hay -- John.Hay@mikom.csir.co.za
