wintryfiy, let me help you!
Listen up!
1. The problem you mentioned about being unable to shut down has nothing to do with the BIOS! Just go to msconfig and uncheck all startup items. If you can't shut down, press ctrl+alt+del to call up the Task Manager and end all your processes. Then you can shut down.
2. sys is not feasible. Windows XP doesn't use command and Io.sys. Also, it might be an NTFS partition! It simply won't be recognized!
3. Wengier's boot disk is not a clean boot disk. This should be clear, but it might still work. But it's not the safest. The real pure DOS boot disk is under Windows 98. When formatting a floppy disk, check the box to copy system files and then format it. Windows XP can also do it, but
Windows 98 formats to MS-dos 7.1
Windows XP formats to MS-dos 8.0
MS-dos 8.0 might have some compatibility issues
4. It's not that I look down on you. Flashing the BIOS is very dangerous. Most people here haven't flashed it. When flashing, be sure to check the BIOS version
Also the type of BIOS
Don't power off during flashing
Otherwise, after flashing, your motherboard will be bricked.
It must be sent for repair.
You definitely can't fix it yourself.
Have you heard of the CIH virus?
It's the same principle!
