求助：［红旗5.0］Via 集成显卡驱动安装驱动-红联Linux系统门户

找一个在RedHat linux 9.0上面相同显卡安装成功的案例，
我在红旗上面不能安装啊。

以下是引用：
[ 先介绍我的计算机配置：AMD1800+，华擎K7VM4主板，MAG786FDII显示器，其他略。

在刚刚安装完REDHAT9.0进入图形界面的时候，就发觉刷新频率只有60HZ，后进入CSDN.NET论坛找资料，上面的帖子都是关于怎么改显示器的参数的，我也尝试过了很多次，在这以前一直忽略了系统没有认出集成显卡的事实，就一直在配置显示器上转来转去。
后来我去了主板芯片的网站上去浏览了一下，我的是威盛（VIA）的，下载了KM400的驱动程序，因为主板自带的驱动程序里面没有显卡For Linux的驱动，经过漫长的等待，终于把KM400 for linux的驱动下载下来了（网络速度太慢）。

心得：按照说明配置下去就可以了，显卡驱动的安装也是比较容易的，在很多的显示器的刷新频率上的帖子的回答都是关于怎么修改XF86conifg的，这个本身也没有错误，但是我个人认为，首先的确认显卡驱动是否已经安装及让系统能够自身测试过，这个才是最主要的，光是修改显示器本身的参数也没有起多大的作用的。也走了不少弯路。

注意：在下载显卡驱动的时候请主意，在芯片厂商的官方网页上有很多的驱动程序，有很多的Installation.txt都说明了该驱动支持那些的LINUX系统，就和windows下也分系统驱动的一样，很多是不能公用的，我的主板的驱动就是这样，我下载的显卡驱动支持FedoraCore，Mandrake，Redhat，其他的是不是支持我也没有尝试过，请各位朋友在下载的时候注意自己的下载的驱动程序是否支持自己的系统。

以下是该显卡驱动的说明程序：

VIA/S3G KM400/K8M800 Installation Notes for Linux XFree86
====================================================================

Installation:
=============

1.How to Install Linux Driver and utility

1.1 Configure your hardware device when intalling Linux

1.1.1 Video Configureation

Please choose another video card, for example "S3 Savgae4 (generic)"
because KM400/K8M800 graphic chip is not on the support list.
We will modify this configuration in step 3 for KM400/K8M800
graphic chip after the installation. If you choose to
"Skip X Configuration", you could configure X after
the installation following step 1.2.

1.1.2 Monitor Configuration

The installation program will attempt to detect your monitor to
determine your machine's best display setting. You may also enter
the horizontal and vertical synchonization ranges for your monitor.
These value can be found in the documentation for your display.

1.1.3 Custom X Configuration

Please choose your login type as "text" because we need post
configuration after the installation.

1.2 Configure your hardware device after intalling Linux

If you choose to "Skip X Configuration" when install Linux. Please do
following step..

1.2.1 Login as root

1.2.2 Check is there a link point to /usr/X11R6/bin/XFree86

# cd /etc/X11
# ls -l X

If there is no link named "X", then do following..
# ln -s /usr/X11R6/bin/XFree86 X

Note:
If you skip the step of X setup when install Linux, there
will be no link named "X" in /etc/X11.

1.2.3 Run "xf86config" to configure your keyboard, mouse and monitor
# xf86config

The configuration program will create the file "XF86Conifg" in the
/etc/X11 directory. If there is the file named "XF86Config-4",
please remove or rename it.

1.3 Install driver and utility

a. Uncompress this file
# tar zxvf KM-K8MXF400xx.tgz(x is version number)
b. Installation XServer driver.
# ./vinstall

1.4 Install DRI library

a. Uncompress DRI.tgz
# tar zxvf DRI.tgz
b. change directory into DRI
# cd DRI
c. Installation
#./minstall

Uninstallation:
===============

2.How to Uninstall Linux Driver and utility
a. Uncompress this file
# tar zxvf KM-K8MXF400xx.tgz(x is version number)

b. Uninstallation
# ./vuninstall

c. Uncompress DRI.tgz
# tar zxvf DRI.tgz

d. Unstalllation DRI library
# ./muninstall

Configuration:
==============

3.How to Configure XFree86

# login as root
