Hm, strange indeed. But I'm quite sure this problem is not related to
DR-DOS or it's memory manager. Since it occured only after you add
more RAM to your system, and I have seen some machines running with
64Mb under DR-DOS, it looks as if it's a hardware or setup problem.
- Please try if the problem disappears using another OS, just to be
sure.
- Check voltage settings for your DIMMs (3.3V or 5V), also check
other jumper settings for interleave/banking/parity etc.
- Please set the DRAM settings in your CMOS SETUP to the slowest
possible values. If it then works, try to increase them again
as long as the system stays stable.
- Your chipset might have a bug not to support 64Mb of RAM,
though I have not yet heart of such an effect.
- Your power supply might not provide enough power to supply the
additional current at constant voltage.
Hope it helps,
Matthias
