[Simh] Problems Booting VAX Emulation on Raspberry Pi

[Mark Pizzolato - Info Comm]

Hi Rob,

You don't show much detail about what your vax780.ini file looks like.

The "%BOOT-F-Unable to locate BOOT file" message is being issued by the code from vmb.exe.  This would suggest to me that the disk image you are trying to boot from has somehow gotten corrupted.  I'd pull that image off the raspberry to an environment where you have a working simulator and attach the disk image as an additional disk on that simulator and use then look around at the details of the contents.

Good Luck.

I have had the 780 emulation running on my Raspberry Pi for some time now. Recently I have had intermittent problems with vmb.exe, the problem seems to have become permanent now though. I have re-copied vmb.exe to the machine but the problem persists. Here is the log:

pi at raspberrypi:~$ sudo ./vax780

VAX780 simulator V3.9-0

libpcap version 1.1.1

Eth: opened OS device eth0

Debug output to "STDOUT"

Loading boot code from vmb.exe

%BOOT-F-Unable to locate BOOT filesim> q

Goodbye

Eth: closed eth0

Debug output disabled

The error about being unable to locate the BOOT file happens about 40 seconds after the "Loading boot code from vmb.exe" message.

Any ideas?

Regards

Rob
