T43 BIOS 8月4日更新到1。22版了 调整显存设置 支持新机型
正好今天重装系统，在用Software Installer自动升级软件时候发现的
昨天刚出的新的BIOS版本，原来最新的是1.08版，版本号的跳变也许是一次重大升级的标志。。。
这是BIOS更新文档里面的摘录
<1.21 (1YET56WW)>
Note:
This BIOS version will only work with Embedded Controller Program Version 1.03
(or higher).
- (New) Support for August 2005 models of ThinkPad T43/T43p.
- Adjustment of video memory settings on ATI-M22 models.
Due to this, the previous BIOS release can't support the new video memory settings.
- (New) Enhancement of security function on power-on:
When hard disk password is set, regardless of other passwords settings,
Wake On Lan from power off state does not work.
- (Fix) Monochrome VGA video mode does not work on DOS environment.
- (Fix) BIOS Fingerprint input screen timeout is set to 13 seconds occasionally.
Its correct value is 40 seconds.
<1.22 (1YET57WW)>
Note:
This BIOS version will only work with Embedded Controller Program Version 1.03
(or higher).
- (New) Adjustment of video memory settings on ATI-M24 models.
Due to this, the previous BIOS release can't support the new video memory settings.
可见，为了新型号机型（含M24 X600显卡）的支持是BIOS升级的主要原因。然而，文档中也提到对M22(X300)显存设置的调整，因此，老机型T43用户安装这个升级也是有用的。
推荐使用IBM software installer安装IBM软件升级和BIOS。
