A DOSBox emulator question...
If I run a DOS MZ executable infected with a virus that attempts to flash my BIOS, will that affect the host computer?
- midwestemo 6y agoAre you talking about CIH? Anyways it could damage your system on dosbox as dosbox has your files mounted a drive so it could wipe that. Virtual machines are the best way to go. Either way it will not affect the BIOS as most boards are UEFI
- 29athrowaway 6y agoBut CIH infects PE executables not MZ executables right?
- midwestemo 6y agoOh, didn't see that. You're correct
- thristian 6y agoNo: - A program running inside DOSBox sees the DOSBox BIOS, not the host computer's BIOS - Even the host computer's BIOS was visible, the host computer's OS is responsible for preventing random programs (including DOSBox) from poking directly at hardware - I'm pretty sure DOS viruses generally predate flashable BIOS, and even if there was a DOS virus that tried to flash your BIOS, it wouldn't know what to do with a modern UEFI setup
