[HELP] Corrupted BIOS: AMI Aptio V ?

[CSparkly]

Hi,
Appreciate any help to resolve this issue.
When powering up a Lenovo V520 10nk mini tower, no booting (black screen), only the CPU fan is working.
The GbE region shows "MAC: 88:88:88:88:87:88" of dumped image.

Notes:
1. BIOS chip: W25Q64JVS1Q
2. Lenovo BIOS update: https://download.lenovo.com/pccbbs/think...t60usa.zip
