We had set up low DOS buffers to allow maximum efficiency in a cache. Most of our applications use dBASE III+, which DEMANDS (it appears) at least 8 DOS buffers. For some strange reason, even allocating more buffers via LOADHI didn't work. We were plagued with scrambled databases, which required major surgery to resuscitate. Since setting BUFFERS=10 and sacrificing a tad in cache performance, I don't have to spend a lot of time playing with the tape backup. As ever, mileage may vary.

How low is "safe" for most uses (windows, mathematica, >etc. etc.). Some guidelines that I use: 1. You can set BUFFERS real low if you use some other disk caching software (SMARDRV, HYPERDSK, SUPERPCK, PC-CACHE, etc.). 2. FCBS can be set to 1 unless you run a lot of old (pre-DOS 2.x) programs. 3. Stacks 0,0 is recommended by Quarterdeck (and I think Microsoft too). 4. I usually set FILES=8 in my CONFIG.SYS and use the QEMM FILES=30 command to load the other 22 into high RAM. - Jim =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "The opinions expressed here in no way represent the views of Digital Equipment Corporation."

FCBS=1 seems to be an "in case I run an old program that needs one" sort of setting. FILES=20 is pretty standard, and STACKS=0,0 saved me 2k, but I'm not entirely sure of the ramifications of this STACKS setting. What values are "good" and/or "safe" will depend on what programs you run, and how they operate. Personally, I don't have an FCBS line in my config.sys, my FILES= is 20 I think, and I believe my BUFFERS are higher than 8, but I can't remember. (PC's at home). My 2 cents. -- --------------------------------------------------------------------------- Mark H.

If I opened a DOS application, then opened windows in standard mode (both under DV), I could no longer open any other window because DV couldn't find any of the *-pif.dvp files. I had to increase my files to 25 to take care of it. This is under DOS 4.01. I haven't upgraded yet... Stephen M.

It would probably be a good idea, that when someone wants to put up his/her CONFIG.SYS, that he/she ALSO put up AUTOEXEC.BAT - and cut down on having to explain one's self a lot. BTW, setting buffers TOO few will cause things like runtime Windows to hang the machine. (This info is in the QEMM book, for those that aren't aware of it.)

I thought that stacks=0,0 was no longer recognized in DOS 5.0. Am I wrong on that?

Use DOS=HIGH,UMB and then you can do away with LOADHI.SYS--use DEVICEHIGH instead. (And you can use LOADHIGH in AUTOEXEC.BAT as well.) Extra savings can be gained by using QEMM's FILES.COM program and setting FILES a little lower, say 10. Unfortunately, the BUFFERS.COM program doesn't work with DOS 5.0--even with Quarterdeck's update. When it does, you can get more memory savings. I can report the same results from 386MAX--which has always worked with DOS 5, even three betas ago. dang

III+ was written about a million years ago. dBASE IV 1.1 includes its own cache now, and only requires a 450K footprint (compared to 516K for dBASE IV 1.0). --Cy-- cy@dbase.a-t.com
