I've built an RSX system (Yipee :-) I've even figured out how to VMR it if I change the configuration or move it to another device. Cool! In [6,54] there's a BRUSYS.SYS which I'm guessing is supposed to be a standalone BRU system. I can boot it on my original disk and it works great, but if I copy the contents of [6,54] to another drive then it doesn't work anymore. I can still boot it, but it no longer knows about any tasks (e.g. BAD, BRU, etc). I'm guessing that it needs to be VMR'ed in its new home so that it can find the task files on the new disk. But what's the procedure for doing this? For the real system there's a RSX11M.TSK file in [1,54] as well as a SYSVMR.CMD file that you use to actually build the bootable system. Where's the command file for VMRing BRUSYS? And what's the unconfigured system that you start from? And what's the VMRM64.TSK file in [6,54] for (I'm guessing it has something to do with all this)? Thanks, Bob
