AMD-K-6 2/500 AFX CPU probably built in 2000!

Its apparent that I hadn't even gotten on base. I am not sure of the vers. of MS Dos but the disk dir doesn't contain any of the files you mentioned. Only the following:
command.com
display.sys
ega.cpi
ega2.cpi
ega3.cpi
keb.com
keyboard.sys
keybrd2.sys
keybrd3.sys
keybrd4.sys
mode.com
autoexec.bat
config.sys
