Thanks. Could you, instead of sending a cookie, include RDTSC emulation in that version?
RDTSC isn't flagged a privileged instruction at boot-up. If it is explicitly set privileged later, then EMM386 shouldn't bypass that.
will help to avoid stupid user questions like "I used FD EMM386 with the HIMEM of MS Win3.1 and now I have only 128k of EMS free?" ;-) ...?
Answer: Use FreeDOS HIMEM like a normal person would. Or real MS HIMEM. Or any of several other popular memory managers. If they're that into celebrating obsolescence, they're probably using a 286 chip, anyway. And if they are a stupid user, a 4309 message would be utterly meaningless to them.
PS: I assume you deliberately put the IDT and a good amount of stack space into DOS-accessible RAM to ease debugging? Otherwise you could save something like 0.5 + 0.2 kB of DOS RAM footprint (current: 3.3k).
I didn't put them deliberately anywhere and the IDT isn't down there. And the stack is where it should be.
