My CH341A arrived. After modding it to 3.3v I have successfully removed the bios password for my first system with RCUnlocker and NEO Programmer. I can confirm the 8 Pin 25B127DSIG is the correct chip to flash.

Here are some notes if anyone else is a novice like me:

1: For this model RCUnlocker just displayed "Unlock Success"
2: I used the GD25Q127C profile in NEO Programmer as there isn't one for the chip.
3: In NEO-Programmer I had to select all 5 options for write IC - Off-protect, Erase, Blank Check, Write, Verify. Without this selected it would...

I have 3 Elitedesk 800 G6 SFF PC with password locked BIOS.

Product Number (same for all 3): 8YM57AV
Serial Numbers: CZC1239T57
CZC1239T5L
CZC1239T3X

The boards are all the same revision (Cersei Rev A)

There are two chips near the BIOS markings (Images Attached):

8 pin Giga Device 25B127DSIG
16 pin 25B256DFIG

I have a programmer on order, it only has 8 pin test leads.

Can you confirm the 8 pin 25B127DSIG is the chip of interest to RCUnlocker and that the tool works with this model of computer?...
