<cough, cough> so ..... you try any of my suggestions to get our beloved to boot?
I was about to suggest the exact same thing yesterday until Chuck(G) made the comment about dos was loaded and trying to read (command.com, I would bet money). So, the old pulling cards etc. seems like to not be required.
We need more info than "nah, didn't work" What didn't work? Making another copy of the boot disk on another machine? Cleaning the heads? Rubbing your head and patting your stomach?
