saving school motherboards from the landfield trip
#1
Question 
hello i face a dilema at work
i have 15 perfectly working motherboards for 8th gen intel cpu's kept in a storage for 6 years now, because we as a school replaced them in new pc's, due to being insuficient for the kind of classroom they were bought for. But we as a school had right to transfer licences to the new motherboards since they are "windows for schools" and we kind of stuck with those boards in storage kept as a coa stickers. never allowed to go online with windows ever again since they have product key in the bios.

Now when the project they were from has ended we have 2 choices.
1 irreperably damage them and scrap them
2 keep in storage forever

but if was able to clear the cd key from the bios chip we had another option, use them as teaching aids for it computer assembly class

the boards are asrock H310M-HDV with ami uefi bioses on 128mbit serial flash chips
sadly i am unable t dump the content without desoldering the chip and asrock only provides patches.
editing rom by hand replacing cd key with empty bits (FF) makes the board unbootable

what software should i use to remove oem info from those bioses entirely and keep them working? i don't want to make slic request i want to learn how to do it, and i can't seems to find any answers with google nowdays

Hey kokodin
I’d recommend trying UEFITool. It’s a powerful tool for editing UEFI BIOS files and can help you remove specific sections, including the OEM keys
It's quite user-friendly, but be cautious and make sure to back up everything before editing.
You might also want to look into AMIBCP (AMI BIOS Configuration Program) for more customization.

Oh yeah the name is so plain i completly forget about the program. I once used that to put chicken images on boot screen (4 years ago). So i kind of know how it works. Might as well replace oem screens while i am at it. Just need to remember the right key enteries.

While i was away from forum i also found this video (deleted) and instantly figured out what was i doing wrong. which was replacing cd key with ff's and not entire oem record. Clearing the record as shown on video worked by the way.
Too bad i had to desolder every chip, dump it by external programmer and then flash back and resolder. but i think it is better than throwing perfectly good "new" motherboards
