Question:

How to check the BIOS manufactured date?

Answer:

You can do this generally one of two ways.

1. Enter the computer CMOS / BIOS and the date may be listed at the top or bottom of the first screen.
2. Do the below to determine the BIOS date with a debug routine:
   
   At the C:\> type debug

   - d FFFF:5 L 8

   After typing the above command you should receive a string similar to:

   FFFF:0000       30 34 2F-33 30 2F 39 38        4/30/98

   The 4/30/98 would be the date of your computer BIOS.
