I have been testing an old motherboard from 1996, a Gigabyte Socket 7 GA586-ATS. Clean installed DOS 6.22 and when I run the mem command, conventional memory shows 631K instead of 640. This is with nothing loaded in config.sys or autoexec.bat, not even himem.sys, just a clean boot. The machine has 8MB EDO ram installed, pci matrox millemium 4mb, and old 2gb hard drive.
In the bios all options are turned off, all Shadow RAM ranges set to off, all com ports, parallel, off etc.
Is there a way I can find out what is using this 9K of conventional memory or free it up to get the full 640k.
