Is possible to detect whether my memory manager is FreeDOS EMM386 and not EMM386 from Microsoft?
Any version of FD EMM386, or need it for just the latest release? Of course, if you get an old enough version, FD EMM386 is going to fail on RDMSR et al, too.
You could mess around grabbing the illegal exception vectoring, using a mini-DOS-extended application, and catch MS EMM386 failing the opcode. You could even handle it properly within a protected mode monitor external to EMM386. Would be slightly complicated, but not impossible.
