The NVM Checksum Is Not Valid

這個是我 Intel i350-T4 最近出現的錯誤訊息,是最近 Power 壞掉之後才發生的,錯誤訊息如下

解決方法也很簡單,下載 Intel® Ethernet連接啟動公用程式、預啟動映射和 EFI 驅動程式 在 Linux 下解開之後,

$ cd APPS/BootUtil/Linux_x64
$ chmod +x bootutil64e
$ sudo ./bootutil64e
Connection to QV driver failed – please reinstall it!

2,3,4,5 就是我們要處理的網路卡,只要下以下指令之後再重開機就會恢復了

$ sudo ./bootutil64e -NIC 2 -defcfg
$ sudo ./bootutil64e -NIC 3 -defcfg
$ sudo ./bootutil64e -NIC 4 -defcfg
$ sudo ./bootutil64e -NIC 5 -defcfg
