把系统升级到ubuntu 8.04 后分辨率变为800*600, Google找到开源的OpenChrome驱动支持P4M890, 就自己手动编译:

border@b0rder:~$ wget http://openchrome.org/releases/xf86-video-openchrome-0.2.902.tar.gz
border@b0rder:~$ tar xvzf xf86-video-openchrome-0.2.902.tar.gz
sudo apt-get build-dep xserver-xorg-driver-via   或者安装 sudo apt-get build-dep  xserver-xorg-video-openchrome
cd xf86-video-openchrome-0.2.902/
./configure --prefix=/usr
make
sudo make install
border@b0rder:~$ sudo displayconfig-gtk
通过displayconfig-gtk 选择openchrome驱动重新启动系统就可以

确定你要格式化的硬盘，我的两块硬盘都是SCSI接口的，可以通过:

border@ubuntu:/dev$ ls sd*
sda  sda1  sda2  sda5  sda6  sda7  sdb  sdb1

如果是USB设备:

cd /dev
ls hd*

IDE设备是:

cd /dev
ls hd*

查看分区信息:

border@ubuntu:~$ sudo fdisk -l
[sudo] password for border:

确定要格式化的分区为sdb1.

开始格式化:

border@ubuntu:/dev$ sudo fdisk /dev/sdb

The number of cylinders for this disk is set to 4462.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

保存退出 w (write table to disk and exit):

Command (m for help): w

创建文件系统:

border@ubuntu:~$ sudo mkfs.ext3 /dev/sdb1

单独挂载分区:
如果要挂载到/svn到话，你要先把现在/svn的文件全部（包括隐藏文件）转移到分割好到分区，再编辑/etc/fstab:

/dev/sdb1   /svn ext3 relatime 0 2

最后重启电脑，重启后查看格式和后的分区信息:

border@ubuntu:/bvcomsvn$ sudo fdisk -l
