查了很多资料,关于linux下的查看bios的几乎没有,于是只能到Ubuntu官方查阅英文资料,累死老夫。终于在一篇教你刷新BIOS的帖子中看到资料。有许多厂商现在包括公用事业,都提供协助本地Linux在BIOS刷新。如果你确定要升级BIOS,最好是使用官方提供的BIOS升级工具。以为升级有风险… 好,下面说Ubuntu下的查看方法。 使用: sudo dmidecode –type bios 将显示如下资料 # dmidecode 2.9 SMBIOS 2.4 present. Handle 0×0000, DMI type 0, 24 bytes BIOS Information Vendor: LENOVO Version: 7VET87WW (3.17 ) Release Date: 07/30/2010 Address: 0xE0000 Runtime Size: 128 kB ROM Size: 4096 kB Characteristics: ………………………. 原文 YOU WILL NEED THE FOLLOWING: 1a) FreeDOS, specifically, this image: http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz 1b) Alternate download location: http://www.mediafire.com/file/26md8h…e/FDOEM.144.gz 2) New BIOS image + flashing tool to be found at the web site of your motherboard/BIOS/OEM vendor.
