I have been unable to boot my VAX 4000-300 from a SCSI hard disk. 
I have tried using an RZ57 (just hangs, no error messages) and an 
RZ58 (endlessly sends the message: "stray interrupt: pc 302a6c vector 
0x18, ipl 31")
     If I netboot the VAX, I can mount the hard disk and view the 
contents, use "df", etc. Thus, the problem seems to be at boot time 
only.
     Ideas?


     Best regards,
