It gives checksum mismatch. We had the same problem, only worse. We wanted to boot SysV on a backup disk (RM05) and couldn't because we have our TU77 and RM05 on the same massbus adapter and an RP07 on the second. The standard DEC midpriced 11/780 configuration (of four years ago), was one tape drive on one massbus adapter and the disk on the other. Apparently Bell doesn't add peripherals to existing Vaxen, they simply buy new ones. The result is that SysV will only boot (from tape), on a machine that has a disk on mba0 and a tape on mba1. What we had to do (I hate to admit it), in order to get the SysV sources was to extract cpio(1) from the distribution tape (all but the boot section are in cpio NOT tar format), and then use cpio and mt to get the stuff we wanted. I got cpio by using mt to get to the right file (system sources) and then cp'ing the whole thing onto a large partition. Then I edited out the cpio sources and compiled it. It is no fun. If you send a copy of your SysV license I'll send you cpio and you can do it that way. Sean McLinden Decision Systems Laboratory 1360 Scaife Hall Pittsburgh, PA. 15261
