Hi, Stas, For Doom and the like it should be easy to incorporate a workaround into DosEmu (it's tougher to do in WinNT because NT's NTVDM.EXE does not expose a proper interface for what is needed, but anyway). If interrupts have been disabled for more than a certain amount of time (easy to detect from within the emulated IRQ0 generator, maybe coupled with the CLI/STI trap handler), DosEmu could force the enabling of interrupts. Then Doom should then get past the "Initializing timer..." lockup and work properly. Can someone test that?
