OpenVMS Firmware Variables

After waiting hours for OpenVMS to install on my DEC3000, I was presented with the following error message when I attempted to boot the fresh install:

%APB-F-BADSYSROOT, System root [SYSA.] does not exist, check bootflags

Very disheartening, however it’s a fairly easy fix.  My DEC 3000 was previously used for OSF/1 (i.e. UNIX), so a boot parameter was incorrect.  BOOT_OSFLAGS was set to ‘A’ instead of ‘0,0’.  I do not yet know exactly what this means, but it’s simple to remedy:


Viola!  The system now boots.  I found the solution here.
