i got a problem with my windows98. it doesnt continue loading the operating system and would display the following message:

-----------------------------------
while initializing device VKD:
Windows protection error. You need to restart your computer.

press any key to continue...
--------------------------------

what's wrong with my OS?
during boot i am presented with options either to boot normally, safe mode, comand prompt, etc.. but all of them would end up with the message above.

According to Microsoft, this indicates a problem with your keyboard: http://support.microsoft.com/kb/q263318/
