Turns out we have this, but not in the default IPL (bootnorm.asm), but in booteasy [1]. So my idea is to transfer this INT 18H call over to bootnorm.asm: - display message if no partition is active or VBR misses boot signature - wait a few seconds to make sure user sees the message, as some INT 18 implementations seem to clear the screen, maybe do not even work... - issue INT 18 - hope for the best - loop in case INT 18 returns Anything that speaks against this method? Any reason it is not in bootnorm.asm?
