BugCheck2Linux
Windows crashed? Dropping you into a linux shell!
vmware_adUUnjU21h.mp4
How to run it?
- Enable test signing and reboot
bcdedit /set testsigning on
shutdown /r /t 0
- Create a service using SC
sc create BugCheck2Linux binPath=C:\where\ever\the\driver\is\BugCheck2Linux.sys type=kernel start=demand
- Run it!
sc start BugCheck2Linux
*4. In case you change your mind then unload the driver to revert the changes
sc stop BugCheck2Linux
How does this work?
We simply register a BugCheck callback. The callback function runs a tiny RISC V emulator running linux.
For the video output we use bootvid.dll and for input we have a horrible simple polling based PS/2 keyboard driver.
Limitations?
- No ANSI escape sequences supported.
- Runs at 640x480 with 16 colors.
- Only works on BIOS systems.
- Is really slow at times.
- Keyboard support is poor. You will have to use CapsLock instead of Shift if you want to access special letters or capital letters. Oh also Backspace does not work.
