This message is being sent to Info-VAX since most DECnet-DOS users seem to be using same to talk to VAXes... We have DECnet-DOS V1.2 and use it on both real IBM PC ATs and on AT clones (AST 286 Premiums). Things worked fine under V1.1 but stopped working under V1.2 on the ASTs. NFT operations would often fail and SETHOST did not work at all (system would hang and require a reboot). The solution to this problem was discovered at Argonne Nat'l Lab by Steve Gabelnick and John Osudar. The information is actually buried in the V1.2 release notes. The problem is that the SCH (Scheduler) Terminate-and-Stay-Resident program assumes there is a real time clock present; since there is no BIOS support for this, SCH must diddle the hardware directly. If there is no real time clock hardware (or the registers are somewhere else), then the system hangs... The solution is to modify the DECnet-DOS startup command file (in AUTOEXEC.BAT most likely) to modify the SCH startup line to read: SCH /S The addition of the "/s" tells SCH to use the system clock rather than the real time clock. With this change, DECnet-DOS V1.2 functions as before on AST AT-clones. = Frank J.
