portege M200 如何刷新的BIOS

恐蛋

在东芝官网下了一个V1.8版的BIOS
本机是1.6版
直接在XP下运行
运行到一半提示用户权限不足
换了Administrator也一样

请教达人改怎么升级BIOS呢？

我的 Portege M200 装了个 矮人 DOS 工具箱，启动之后选择 DOS-> 安全魔石，运行 CHGBIOSA.EXE BIO0009T.COM ,回车，即可成功。之前遇到的“The user is not authorized to update BIOS” 麻烦一扫而空。

To update BIOS for my newly purchased used Portege M200, I tried many many times. Thanks for the reply here. I downloaded a "airen DOS tool set" and install it. When finished I am able to boot to DOS mode. When boot into DOS, just select the safe mode. After boot, go to the BIOS update directory that you save. Run CHGBIOSA BIO0009T.COM, then you can success. You don't have to be stocked by the prompt of "The user is not authorized to update BIOS."
