Strange, I am using a DTK PEM2000 20 MHz with over 8 Megs of RAM, and DTK Bios 4.26 and everything works fine. I recently upgraded the Bios from 4.25 to 4.26 due to the configurable hard drive ability of Bios 4.26. I am currently running Windows 3.0 in 386 Enhanced mode...no problems.

Here is hoping that one you tech gurus have some ideas I have been running a DTK 386 25mh for over a year, no problems. (387, 64K cache, pem2500 motherborad, DTK bios rev 4.25 (dated 6/12/89 running Dos 3.3). I run a lot of big statistical programs that work in protected mode using various extended compilers (eg Phar Lap). This was with 4M memory on the motherboard. The motherboard can handle 8M so I upgraded yesterday. Fine. Machine finds 8M, programs like Norton and others all recognize 8M, diagnostics tests out 8M and say okay. BUT The only programs that work are those using 8086 mode (eg word procsessing and utilities). Everything that uses protected mode hangs up instantaneously, giving me message like "OS386 paging system fault" or "Processor exception while running control program, protected mode." I have checked the switch settings and they are right. When I install a ramdisk with pckwik it seems to work (although when I use their cache which also sits over 640K it seems to trash my fat, so I assume some problem). The memory itself checks out and several different diagnostic programs say that the 8M memory is there and okay. So any ideas what I should do. I obviously need to just take out the extra 4M and make sure that things still work with 4M Ram. But while I am tinkering is there anything else I might try. In particular, could a BIOS upgrade (or change to Phoenix or AWARD) make a difference? Any other ideas. Could the 386 have a page bug that only shows up in going past 4M?
