[原创]How To: 用ubuntu Desktop LiveCD测试电脑硬件/兼容性

[hnxtddd]

呵呵,想法不错,真的到了电脑城里,都按部就班也记不得那多了啊

收藏了！

MS要开始灭D版XP了。。
赶紧试下额滴机子。。
开始准备投向免费的Ubuntu的怀抱。。。。

多谢骨头!

live cd 的显卡测试问题，你可以看下：

Using Desktop CD Persistence
Live CDs like the Ubuntu Desktop CD provide an easy way to temporarily turn any compatible computer
system into an Ubuntu Linux system. However, the fact that most live CDs don’t provide any sort of persistent
storage for configuration data, custom applications, and so on (other than manually copying files to
other local or networked storage) limits the practical usability of Live CDs to simple demonstrations, general
one-time experimentation, rescuing data from crashed systems, and for general system repair and
recovery efforts. Until now, that is.
The Ubuntu 6.06 Desktop CD provides a built-in mechanism for recognizing an external storage device
with a special name at boot-time and using the contents of that device to restore desktop settings, application
configuration files, and even installed applications. The amount of custom configuration information
and installed applications that you can save and restore is only limited by the size of the external storage
device that you use. The requirements for taking advantage of this capability are the following:
n The external storage device must be one that can be found by the Desktop CD kernel when it boots.
n The external storage device must contain a Linux filesystem that is supported by the Desktop CD
kernel. VFAT, NTFS, and HFS+ filesystems will not work—the filesystem must be an actual
Linux filesystem. Ext2 or ext3 filesystems are recommended for portability.
n The filesystem on the external storage device must have the name casper-rw.
n You must add the persistent keyword to the kernel command line when you boot from the
Desktop CD.
The most common devices used for persistent storage with the Desktop CD are USB devices. USB sticks
(a.k.a. pen drives) are extremely portable, but provide a limited amount of storage. An external USB hard
drive is a better alternative if you need to install applications, related files, and other data that would exceed
the amount of storage available on a USB stick.
If you are using an Ubuntu Desktop

使用桌面型CD的持久模式

像Ubuntu这样的Live CD用一种简单的方式将兼容机临时变为Ubuntu Linux机器。不过事实上，大多数的Live CD并没有提供任何长久保存配置文件或自定义应用程序的方法（除了手动复制到本地磁盘或者是网盘中），这就限制了它的实际可用性，也就只能用来做简单的示范，一次性的实验，崩溃系统数据救援，系统日常维护。
而Ubuntu 6.06版的桌面型CD则提供了一种内部机制，使之在开机时能识别有专用名的外部存储器并利用其空间存储桌面设置，应用程序配置文件，甚至安装的程序，且仅限于其大小。
要用到这个功能有以下要求：
1、开机时桌面型CD内核要能检测到此外部存储器设备；
2、此设备须格式化为Linux内核支持的文件系统，比如Ext2或者Ext3，而不能是VFAT,NTFS和HFS+；
3、此文件系统必须叫casper-rw；
4、开机时须在内核命令行中添加 "persistent"。
USB设备是桌面型CD用的最普遍的持久存储，最轻便莫过于U盘，但容量太小。如果需要安装程序，相关文件和其他数据的话将超出U盘容量，这时USB移动硬盘就是一个比较好的替代品。

这跟显卡测试问题有什么关系？？

这年头，自己买，怕被宰，托别人买，更加怕被宰，想想算了，买品牌吧，又有点不甘心～

[逍遥高手]

这办法不错 适合准备买新电脑的人

这个方法有点繁琐了,如果这么干,倒不如搞个U盘系统好了.

[gdzhljw]

顶一个,以后真的要试试

[查理德]

要测试的这么多！我就以为声卡显卡没了

[onxiey]

不错的思路，是个好办法！

[liput]

这样的文章非常地好哦。
充分体现了LINUX下工具的灵活多样性，并不是能够简简单单动一点手脚就可以蒙敝的。
谢谢楼主！～
