To Install

3.      Disable "Bios Gaurdian" in Setup.

4.	With floppy installed, restart system.

5.	At the “A” prompt, type “Flash820A” (without the quotation marks).

6.	Enter your new .bin file “IEK420L.BIN” and press Enter.

7.	Answer yes (Press “Y”) to back-up your old Bios. Enter in a name like “oldbios.bin” 
        or “backup.bin” don’t forget the .bin

Notes:

·	Before flashing any Bios it is highly recommended that you take time to write down all setting in Setup for future reference.

·	This is a modded version of Emachine’s IEK420.bin. 
        By using this modded version your System Restore Disks should still work on your system. 
        I needed no Window’s Re-activation or Re-registration after flash.

·	Please, take the time to let all of us know your feedback on these Bios at the EmachineUpgraders Forum. This is the only way we’ll know if our work needs any adjustments. 
        All feedback welcome.



A Special Thanks to shankar for testing.
