Yes, seems pretty strange to me.
Anyway, you should be able to copy the BIOS from chip 2 back into chip 1.
Before you start you will need to load optimized defaults in BIOS.
D NOT enable Fast Boot or anything in the BIOS once you have reset it.
Shut down the PC totally
If possible use a wired keyboard for this next step as I have found wireless ones can be a bit hit and miss.
Make sure that the Motherboard is set to only BOOT from the good chip (BIOS 2) If you're not sure how to set this, check out the motherboard manual.
Start the PC and press both the ALT & F10 simultaneously (as you would hit the Del key to go into BIOS) You may need to keep pressing the two keys several times before BIOS recognizes the key strokes.
Once BIOS has logged the fact that you have done this, you should get a screen up stating something like: "Do you wish to copy BIOS from chip 2 to Chip 1?" (I can't remember the exact wording here but it is hopefully close enough for you to get the idea.) Hit yes and then the process is automatic.
Once the BIOS has been copied over, shutdown the PC. Reset the BIOS switches so that you are now going to BOOT from chip 1, restart the PC and go into BIOS. Load Optimized defaults, reboot, go back into your BIOS and re-apply your settings.
Hopefully, everything will now be back to normal and you will have both BIOS chips up and running.
