Hi everyone, I´m new for this forum

I'm working on unlocking the BIOS password (lock code: 8FC8) on a Dell Latitude 5400, and I'm trying to do it myself. The motherboard model is LA-G891P REV 0.1.

I've purchased a few tools from AliExpress:

• A CH341A programmer with a 5V to 3.3V voltage converter:
  https://es.aliexpress.com/item/1005008172690265.html
• A WSON 8x6mm clip adapter, to avoid desoldering the chip (since I'm not very good at soldering):
  https://es.aliexpress.com/item/1005008517042667.html

I downloaded AsProgrammer v2.1.0.13, installed the drivers, and confirmed that the CH341A shows up correctly in Device Manager.

However, when I connect the programmer to the chip, AsProgrammer shows:

SPI Flash ID (9F): 000000

Then it prompts me to “Search IC.” The problem is, my chip is a GD 25B256DYIG, and it does not appear in the list. I also tried the "Detect" button, but nothing happens.

I'm not sure what IC to select manually in AsProgrammer, or what I'm doing wrong.
Any help would be really appreciated.

Thanks in advance!
