I used this link from another post in this forum - https://www.sendspace.com/file/i30hum
*edit: inside it has BACKUP_Tools12.exe and "Universal Bios Backup.exe"

However I don't have a Windows installed so I used a Hiren's BootCD PE iso to run it

Didn't tested for anything malicious but it seemed fine

Hi Dudu2002,
I have an Acer Aspire E1-531G (CPU upgraded to i3-3320M). At some point I updated my BIOS (don't recall the exact starting version, possibly 2.15 or 2.17) to the current 2.21, and after that my internal card reader stopped working completely — it doesn't enumerate at all, not in Windows Device Manager, not in Linux (lspci/dmesg), so it looks like it's not being powered/initialized at the firmware level rather than a driver issue.
I compared my current 2.21 dump against a 2.17 update package I found online:

• Same 315 drivers in both — nothing added/removed
  
• Only 14 modules differ in content between the two
  
• PCHPolicy changed the most (~53% of bytes differ)
  
• Acer's own A01ODMDxeDriver and A01ODMSmmServiceDriver also changed — these seem like the most likely place for board-specific device power/GPIO handling
  

Attached is my current 2.21 dump. Could you take a look and see if there's a way to restore the card reader's init/power state without breaking anything else? Happy to test.
Thanks!
