Hi folks,

I have a SPARCstation 20 running SunOS 4.1.3_U1 released in 1995. From a
month ago the clock is about three hours behind the real time. An IT staff
tried to help me to reset the date but failed. And after he deleted some
time/zone files, my computer got frozen. When I turned off and on the
power, it does not boot to normal unix window. I installed a new NVRAM/TOD
chip and the problem is still the same.

Now it only displays the following and stuck there. I desperately need it
back to work. Any help will be highly appreciated.
