The Question is: I am installing OpenVMS 7.2 on an AlphaStation 200 4/233. The box has all Digital parts (CD, floppy, hard disk) and Kingston memory (64MB). At some point in the install process I always get a BUGCHECK. I researched this problem on the Compaq site and see that the OpenVMS team usually believes this is a SCSI termination and/or other hardware problem. I made doubly certain that my SCSI hard drive and CD are terminated correctly. I have made several attempts with two different models of Digital hard drives: RH27A-BU and RH31E-DB. I had no problem upgrading the SRM console ROM to version 7.0-9 prior to installing OpenVMS. I can run OpenVMS from the installation CD, manually mount the hard drive, initialize it, etc., but at some point in the full installation process the BUGCHECK will appear. The last attempt got all the way to the point where I had initialized the drive, mounted it, registered the license, chose all the installtion options, etc. Here is the complete error output: Portion Done 0% **** OpenVMS (TM) Alpha Operating System V7.2 - BUGCHECK **** error log buffers not dumped to SYS$ERRORLOG.DMP bugcheck code = 00000215: machinechk, machine check while in kernal mode Crash CPU: 00 Primary CPU: 00 Active CPUs: 00000001 Current Process AXPVMS_INSTALL Current PSB ID = 1 Image name = DKA400:[SYS0.SYSCOMMON.][SYSEXE]PCSI$MAIN.EXE Cancelled memory dump, file blocks left = 0, Dump PTE address = FFEE00 halted CPU 0 halt code 5 halt instruction executed PC = ffffffff8009c5f0 CPU 0 booting Please help. John Fredrickson Washington, DC The Answer is : Please contact your hardware support organization. Without very specific details of the hardware and the hardware configuration, this failure could easily have a variety of causes -- and yes, the potential causes here include a misconfigured SCSI bus or errant SCSI hardware. A SCSI bus must have precisely two terminators, one at each end of the bus. It would be very unusual to see two devices with termination on the same bus. At the very least, this would imply the devices were on either side of the controller. Otherwise, you might have an over-terminated bus. And SCSI bus problems. The RH series SCSI devices are more commonly refered to as the DSP series -- these are disks that were made available to system vendors, and are not particularly supported by OpenVMS. Various OEMs tended to customize the firmware in the DSP series for the local requirements -- the RZ-series equivalents of the DSP series were customized for the expectations of OpenVMS, for instance. For general information on connecting (unsupported) SCSI devices to OpenVMS, please see the OpenVMS FAQ.
