Message-ID: <1991Jun18.235933.18532@ingres.Ingres.COM> Date: 18 Jun 91 23:59:33 GMT Reply-To: sergio@Ingres.COM (Sergio L Aponte) Organization: Ask Computer Systems Inc., Ingres Division, Alameda CA 94501 Lines: 40 System : 386/33 64K cache 4Mb RAM Megatrends BIOS 200Mb hard drive, 5.25 HD (A:) and 3.5 HD (B:) Problem: System came with DOS 4.01 on the hard drive. WHen I tried to add emm386.sys to the config.sys, I lost access to the flopy drives. Ventura loved it, but no flopy drives was a problem. If I take the emm386.sys OFF the config.sys, I can leave himem.sys and the mouse driver in there and all works ok, other than ventura (and some other software) complains of shortage of memory. Thinking it might be a DOS 4.0 BUG, I upgraded to 5.0 right away. The 5.0 did NOT put emm386.exe in my config.sys, but added "DOS=HIGH" to it, and I lost my flopy drives again. I took the "DOS=HIGH" out, all works ok. I added "DEVICE=C:\DOS\EMM386.EXE RAM" and lost my flopies again. So I am back to HIMEM and the mouse... "LOST the flopy drives?" That means that when I do a "dir a:" or "b:", I get 1) locked up (reboot) 2) my screen printed (!) 3) a partial list of files and then garbage Other "info" : The system has a shadow ram, some 64K @ ffffff (I might be missing an "F"). I disabled this, no change. Do I have to specify this area to emm386 not to be used? How? What else can I check? I called my "clone" vemdor, they said it was "DOS"es fault, to get querterdecks QEMM. How do I know if this is true??? Thanks for any/all help Sergio -- =============================================================== _|||_ Sergio L.
