Found this it may help..
While reloading Win98 to my computer, a message appears on the screen which I don't understand, nor do I know how to fix the problem whatever it might be.--Here is the message exactly:
"While initializing device NDIS: Windows protection error.-You need to restart your computer."
After numerous times of restarting my computer, the message still appears and prevents me from continueing the installation of Win98.--Any help appreciated, please simplify answers I am 90 years of age. --Thank You
NDIS is associated with networking, if you have a NIC, remove it, if you have any external devices (printers, scanners...) connected, remove. format, re-try.
