No EMS under Win98

[Keith Waters]

I have a PbDos3.5 program that I’m trying to run on a Win98 machine. The program uses DIM VIRTUAL and so requires EMS support. The program checks for the availability of EMS with the following code and when I run it on the Win98 box it issues the error message.

IF NOT FRE(-11) > 500 * %Kbyte THEN        'Currently we need 384 Kbyte EMS
  CALL SoundAlert
  PRINT "ERROR. EMS memory not available."
  END
END IF

When I look at the properties (PIF) for the executable, on the “Memory” tab under “Expanded (EMS) Memory” I see “The computer is not configured for expanded memory in MS-DOS sessions”. When I click the “Details…” button I see “The third party memory management software has not been configured for expanded memory. Consult the product documentation for instructions on how to enable expanded memory”. All other memory types, Conventional, XMS and MS-DOS protected, on the Memory tab are set to Auto.

In my config.sys I have the following.

dos=high,umb
device=c:windows\himem.sys
device=c:\windows\emm386.exe 1024 RAM

It’s been some time since I’ve played with DOS/PbDos so I’m very rusty on these things. I can’t remember running across this problem before and have had no trouble running the program on XP and other Win98 machines.

Have had this happen and corrected by creating a new shortcut.
Went through every option in the pif without seeing any
differences. The new shortcut has fixed it everytime.

No Mike – just tried that and it doesn’t work – still the EMS is disabled.

I have EMS back. But I don’t quite understand how. I edited the config.sys to

device=c:\windows\emm386.exe NOEMS

and rebooted. The pif properties, correctly, said EMS is disabled with this. Then I edited the config.sys back to

device=c:\windows\emm386.exe 1024 RAM

and now everything works ok. Perhaps it was a bit like you said Mike – give it a kick and it works.

Hello Keith!

You can emulate EMS functionnalities in Win98 if you add one of this lines in the system.ini:

[386Enh]

EMMPageFrame=C800
; provide EMS/XMS, but i can't use it because of a big problem with my Ms-Dos programs which use the Maxlib libraries:
;$link "MAXLIB.PBL"
;$include "MAXLIB.BI"
;InitXMSArray


EMMInclude=D400-E3FF
;no problem for me and the Maxlib lib.! All my programs run fine !
;following adresses work also on my PC
;EMMInclude=D800-E7FF
;EMMInclude=DC00-EBFF
;EMMInclude=E000-EFFF
;EMMInclude=D000-DFFF

I have also no need of Himem.sys and EMM386.exe in my config.sys
