I'm trying to create standalone BACKUP on an RA81. I did @SYS$UPDATE:STABACKIT, and followed the directions, no problem. However, in the "Guide to System Management...", it says to change the line in DEFBOO.CMD that reads "D R5 0" to "D R5 E0000000" However, the line in my DEFBOO.CMD reads "Deposit R5 4000" Should I change "4000" to "E0000000" or "E0004000" ? Thanks in advance Tom Williams

If you peruse your console media, there should be a file called BOOT.HLP or BOOT.CMD that has some info as to whats there. The most significant nybble is used to hold the root number to boot from. In the case of Standalone Backup, which uses SYSE, the mask is "E0000000". The "4" in your R5 tells the bootstrap what type of memory controller you have. To boot standalone backup on your system, set R5 to be "E0004000". - Dan <dcottler@rca.com>

I don't recall offhand what it is that bit 14 does, but I've always just booted using E0004000. The important point is that the high-order byte determines which rooted directory to boot from, and since you probably want all the other flags the same as for a normal boot, only that byte need be changed. I assume, by the way, that the RA81 already has the VMS system sitting in [SYS0...]. If it doesn't, STABAKIT will put the standalone kit in [SYS0...] in preference to [SYSE...].
