Willi uploaded screenshots: > https://nextcloud.iww.rwth-aachen.de/index.php/s/z9bqWBdom8A8nZz before you posted "the flag gets cleared even before the first driver is loaded, depending on what gets selected in the FreeDOS boot menu (probably more which keys get pressed to achieve the selection)." the photoshow above doesn't show that. it shows that the flag sometimes is misdetected to 00 in most cases remains constant. sometimes - during menu selection - magically gets redetected as 10 besides what Bret already posted ("the extended keyboard gets detected by BIOS POST and remains constant") which I agree with 100%: the photos don't tell, if Willi is letting the keyboard alone during POST, or ( as your mails suggest) hitting the keyboard just to show that it doesn't work reliably. > 40:96 is zero at early kernel stages, and is eventually changed to 10h when > navigating the FreeDOS boot menu or some specific > keys are pressed when the BIOS POSTs.
