Description

It shows your computer's BIOS time. Make sure you don't run it on Windows 2000, becasue Windows 2000 does not fully support BGI in Dos.

More Info

Sends Minutes, hours, and seconds to the bios function.

Make sure you don't run it on Windows 2000, becasue Windows 2000 does not fully support BGI in Dos.
