The following problem came up on a 386 20 Mhz ISA PC using MSDOS 4.01 when attempting to run AutoCad release 10. A message to the effect that there were not enough FCBs appeared briefly and the user was dumped back to the DOS prompt initially from within the drawing editor. We tried the following settings of the FCBS parameter in the CONFIG.SYS file: No FCBS parameter in config.sys - problem as described above. FCBS=0,0 - Couldn't load AutoCad, complained about insufficient FCBS or FILES= FCBS=8,0 - ditto FCBS=8,2 - ditto FCBS=255,30 - Appears to work although the initial problem didn't manifest itself until after about 10 minutes of editing the drawing. We also tried increasing FILES= and BUFFERS= with no apparent effect. What is the story with FCBS under MSDOS 4.01? I've heard others who have had other weird things happen which seemed to implicate this parameter.

The FCBS can "wrap around" at the 32MB mark and trash your disk. That's the reason that share.exe is provided. Besides handling file sharing, it also does some mumbo jumbo with FCBS so that they work properly. That may help your problem, but I wouldn't be suprised if the total solution is some combination of share.exe and the FCBS config variable. ------------------------------------------------------------------------ Patrick Draper In times like these it is helpful to cps.msu.edu remember that there have always draper@cps.msu.edu been times like these. ------------------------------------------------------------------------
