No, I see no error messages with QLA12160 HBA everything seems to be OK, 
except that I cannot access the device. I am able to access 
/proc/scsi/sg/device_strs and read the device string for the tape. As 
for the ISP1040 the qlogicisp driver simply prevents the system from 
mounting the root fs, even though the fs resides on an IDE disk.
BTW. The QLA1260 is now being used in my PS with WIN98 and seem to work 
OK with a SCSI disk.
