The one on my most recent Zenith DOS disk is dated 6/29/89. So suggestion #1 is don't use anything older. His second suggestion is that the 386 bios has also been through several revisions, with the current release number 3.2 something. The most recent one we now have is 2.9B, but he is sending us a 3.2 BIOS to see if it helps with another problem we have had. If the machine is under warranty, new bios chips are normally requested through your dealer as a warranty repair. We use several of the 4MB boards here, but only in dedicated servers. They work well in that use (1MB base, rest extended.) -- Jim Strasma, Network Specialist @ WIU

I have no problem loading IPX and NET3 high, and other programs that want to use the EMS have it (including multiple DESQview windows). The setting I use is: DEVICE=QEMM.SYS RAM NV NS X=A000-CFFF X=E000-FFFF I=B000-B7FF I=E800-EFFF The Zenith VGA board shadows its ROM into RAM at E000-E7FF, and if you fail to exclude that section (QEMM doesn't see it as used!), the machine will lock up. I have heard rumors that there is a program that will unshadow that ROM so that you can recover that space. The hardest part is configuring the NIC so that there is room for both its buffer and QEMM's page frame, both of which will want to be at E000. Because of the aforementioned VGA shadowing, you need the NoVideo switch. I don't know why the NoSort switch is necessary, but it is. That one tooks some experimentation to find. ----------------------------------------------------------------------------- Rick Beebe (203) 785-4566 ***** ***** ***** * * Biomedical Computing Unit * * * ** * Yale University School of Medicine * * *** * * * 333 Cedar Street, New Haven, CT 06514 * * * * ** * * * * * BEEBE@YALEMED.BITNET beebe%biomed.decnet@venus.ycc.yale.edu -----------------------------------------------------------------------------
