Hi,
1) IOS is an operating system installed on Router.
2) Flash is a startup and running configuration on IOS
3) TFTP is a freeware one can install anytime.
If Flash is deleted one can restart router by restarting
while restarting press Pause|Break it will take to router
IOS mode copy the startup configuration to TFTP server and
try to do changes and restart router and you are into
router config .
