Hello guys,
I'd really appreciate if someone could help me to remove the whitelist from the T530 BIOS v2.65 in order to be able to install and run Atheros AR5B95 WiFi adapter (168C/002B/17AA/30A1).
Manufacturer and model: Lenovo Thinkpad T530 (2394DN4)
UEFI BIOS Revision: G4ETA5WW (v2.65)
Embedded Controller Program (ECP): G4HT39WW (v1.13)
Original UEFI BIOS by Lenovo: https://download.lenovo.com/pccbbs/mobiles/g4uj29us.exe
Aftermarket WiFi adapter to be installed (vendor/device/sub-vendor/sub-device): Atheros AR5B95 168C/002B/17AA/30A1
As far as I learnt from previous threads, there are two EEPROM chips on the motherboard: MX25L6406E (8192KB) and MX25L3206E (4096KB). The BIOS region seems to be allocated into the MX25L3206E chip. I disassembled the notebook and located both chips on the motherboard. The next thing I did was to make full dump of the BIOS chip using a combination of RaspberryPi + SOIC Test Clip + FlashROM. I made five dump files (4096KB) with matching MD5, so I think that reading the EEPROM content went fine. You can find attached one of the dump files. It will be nice if somebody could help me with the appropriate BIOS modification in order to install my new Atheros WiFi adapter.
I will donate after successfully flashing the modified BIOS and assure that my notebook is booting fine with the newly installed adapter.
Many thanks in advance!
