- Booting a 4000/300 VMS 5.4-2, I get the following error early in the
- boot process:
-
- %SYSGEN%W-NOMSG, Message number 00000910
- [SYSEXE]XPDRIVER.EXE
- %SYSGEN%W-NOMSG, Message number 00000910
- [SYSEXE]XPDRIVER.EXE
-
- This occurs after loading the MSCP disk server but before mounting the
- disks. The 4000 being booted is the disk server for a cluster of 6 VS
- 3100's.
-
- There is no XPDRIVER.EXE anywhere on the system that I can find, but
- there also is not on another VMS 5.4-2 system which does not exhibit
- this message.
-
- What is the source of this message, and is it something I need to
- worry about?
-
- Typing "EXIT %X910" reveals that the error is "no such file" - consistent
- with your statement that there is no such file on the system.
-
- The message you are seeing is coming from SYSGEN when it is trying to
- configure in some device for which you don't have the driver. There are
- two possibilities:
-
- - You've got an explicit attempt to load XPDRIVER somewhere in your
- startup files;
-
- - SYSGEN is doing an AUTOCONFIGURE and is finding some device that,
- according to its built-in tables, needs a driver named
- XPDRIVER - which you don't have.
-
- A copy of SYSGEN's tables is included at the back of the SYSGEN manual. It
- lists XPDRIVER as the proper driver for the PCL-11. Those with long memories
- will recall that the PCL-11 was a Unibus device that allowed you to connect
- multiple '11's together. If I remember right, it worked by making memory
- visible to remote processors in specific "memory windows". It was never
- supported on the VAX, and there's certainly no way you could connect it to
- a 4000. This leaves one of three possibilities:
-
- - There's something in your 4000 that is responding in a way that
- looks enough like a PCL-11 that SYSGEN is being fooled;
- - The XPDRIVER mnemonic has been re-used for some other device.
- (Any "X" device would likely be a high-speed communication
- option; for example, XQ is a Q-bus Ethernet adapter.)
- - SYSGEN has a bug.
-
- You can use SYSGEN's (long misnamed) SHOW/UNIBUS and try to figure out what
- devices haven't been configured - but are there really devices on your system
- that you don't even know about? You might want to check - but I'm inclined
- to lean toward an explicit load attempt, or a SYSGEN bug.
