Not necessarily a VAX, but on something that either has DECnet or MOP.  Most, but not all DECservers download it's OS from the network. So you need something on the the local network with the correct file to load when the DECserver boots and makes the request.

It's the DECserver's OS so yes to both.

If you have access to any of the VMS software distribution CD's it on there. For the DS300 it would be in the DS3C022 directory on the appropriate CD.  According to Wikipedia you need the SH1601ENG.SYS file <>Online images of the CD are available several places online. has some, VAXHaven as several <>

For downloading the file into the DECserver you need an OpenVMS system with DECnet and that kit you get from the distribution CD will tell you how to install.  Or you can follow this instruction to set up downloading from a Linux system <>

Some of the software was available on one of the VMS Freeware CDs.  I don't remember which one though and it's not in my notes.
