Ok I'll run those MEM flags and see what's up./

I don't use smartdrive. I was never quite sure what it did anyway.

Well I think I see the problem, but I'm not sure how to fix it. On my Win 98 box it appears that MSCDEX is entirely in conventional memory rather than upper memory. I think it's because there's not enough free upper memory it needs 27K and I have 56K total, 32K used, 23K free. On my other system (the 486) it has more free total upper memory for some reason (why is this?) so MSCDEX fits nicely into it with room to spare. Any way to fix this?

EDIT: By changing my FILES to 40 and Buffers to 30,0 (as in my 486) and now I have 597K free which I can live with. I just wonder why the big difference in total Upper Memory between the two systems?

You can run MSD.EXE and go to Utilities->Memory Block Display and Memory Browser. Compare between the two systems to see where the extra memory is being used and what's using it. MSD is a built-in Microsoft utility and it should run from any path.

The more I learn, the more I realize how much I don't know.

I dimly remember that himem.sys and emm386.exe needed more memory for themselves in Windows 9x versions.

my current config.sys for 98se on Core i7 machine, with buggy wrong configured 10 KB XBDA:

DOS=HIGH,UMB
STACKSHIGH=0,0

SET PATH=C:\;C:\BOOT;C:\NC;C:\NC\QPV;C:\INFO;C:\MDOS;C:\DOS;C:\ARC;C:\RUS;C:\DOS7;C:\WINDA;C:\WINDA\COMMAND

; INSTALL[HIGH] will exec at end only
INSTALLHIGH=C:\160331\SHSUCDX.COM /D:UDVD1 /L:E /R /C /Q

my autoexec is empty. i have 625 KB low mem free, and 635 on my second machine, P3, where used good old 1 KB XBDA.

That would make sense, I keep forgetting that WIn 98 DOS isn't exactly the same as DOS 6.22

What are some good values for FILES and BUFFERS? I seem to recall that FILES is the number of simultaneous open files allowed and 30-40 is a good range for that, but I'm not sure what BUFFERS does or what a good number is for it. Also do I need STACKS anymore?

if u really want set BUFFERS/FILES/etc manually - use BUFFERSHIGH/FILESHIGH/etcHIGH.

It doesn't matter; Win98 SE will make them HIGH by default, if high memory is available, unless you use DOS=NOAUTO.

Once again, I'm posting my current startup files on Win98 SE, and the resulting memory layout.

  • C:\DOSW is where I keep the DOS files of Win98 SE; normally you should use C:\WINDOWS.
  • In Autoexec, I have 3 different audio sections, depending on which card I have installed (currently it's the AWE64).
  • CTCME.EXE is the standard Creative CTCM, which I hacked so it does not complain about running under Win98 SE DOS.
  • FASTKEYS.COM is a small command file which increases keyboard repeat rate to maximum.

P.S. It would be nice if the forum settings were adjusted so that larger code blocks can be accommodated without forced scrolling, or provide a different way of posting fixed width text (like [pre] or [monospace]).
