ThinkPad T61 安装 Windows XP 的设置

Wed, Apr 23, 2008

ThinkVantage 帮助文档中有一个方法 (Access Help --> Advanced configuration --> Installing a new OS --> Installing Windows XP)。把 CMOS 设置成 AHCI 模式，先安装南桥芯片组驱动，再安装 Windows XP 操作系统，因为 Windows XP 安装 CD 中没有 SATA 硬盘接口驱动。帮助文档建议从 SCSI 控制器或 RAID 卡安装，否则安装过程中会出现蓝屏。实际上，在 BIOS 中把 SATA 设置成Compatibility 模式，可以绕过缺 SATA 驱动的限制。

关键步骤：

进 BIOS --> Config，把 Serial ATA(SATA) 设置为 Compatibility 模式（默认为 AHCI 模式）；
依次安装：
- Windows XP 操作系统，
- 主板驱动(Intel Chipset Support for Windows Vista, XP, 2000)，
- 南桥芯片组驱动(Intel Matrix Storage Manager Driver for Windows XP, Vista，关机)；
开机，进 BIOS --> Config，把 Serial ATA(SATA) 改回 AHCI 模式；
安装其他驱动……

两个小工具

Tue, May 29, 2007

(for Microsoft Windows)

1. AddMyNote (70K): 给 Microsoft Word 文档的脚注标号加方括号。

MD5 (AddMyNote.exe) = 2542224692558d7c04a3c536af50b867

中文文档中脚注标号的数字一般要求用方括号括住，而 Microsoft Word 默认脚注标号不带括号。这个小工具提供的宏和模板可以给脚注标号加（或去掉）方括号。安装这个插件后会出现新菜单，可以批量转换，使用很方便。其前身是 AddMyFootnote。

安装过程中不必改变默认路径，解压后出现安装文件夹 AddMyNote_Setup/，可在安装成功后删除。

2. notice-ins (21K): 定时提醒，功能简单，挺好用的。

MD5 (notice-ins.zip) = 5fa0d3675559133394be551350ba45ea

vim-latexsuite citation completion

Thu, May 17, 2007

Q: Why can't I use \ref{ <F9> or \cite{ <F9> completion in vim-latexsuite on Windows?

A: It is mainly because of the spaces in the path or filename, that's Windows style. Just add an environment variable named $HOME with no spaces in the path.

ATTENTION: 1. This would affect other relative applications. 2. I have installed Python, as the latexsuite manual recommends.

配置 SCIM

Thu, Feb 22, 2007

环境：Debian (3.1, sarge): Xorg (1:7.1.0-11); GNOME (1:2.14.3.5); SCIM (1.4.4-7)。

1. 设置 locale

# dpkg-reconfigure locales

选择 locales，如 en_US.UTF-8, zh_CN.UTF-8, zh_CN.GBK。

2. 安装 SCIM

# apt-get install scim scim-gtk2-immodule scim-modules-socket \
> scim-modules-table scim-pinyin scim-tables-zh

3. 修改 /etc/gtk-2.0/gtk.immodules

- "xim" "X Input Method" "gtk20" "/usr/share/locale" "ko:ja:th:zh" 
+ "xim" "X Input Method" "gtk20" "/usr/share/locale" "ko:ja:th:zh:en"

- "scim" "SCIM Input Method" "scim" "/usr/share/locale" ""
+ "scim" "SCIM Input Method" "scim" "/usr/share/locale" "zh:en"

4. 重启 X

中、英文环境下都可以输入中文。

硬盘安装 Debian

Thu, Feb 22, 2007

1. 下载安装文件

从 Debian 镜像列表中选择镜像，下载以下三个文件，存放到 C:/debian/ 目录下：

debian-31r4-i386-netinst.iso (112M)
vmlinuz (798K)
initrd.gz (2.9M)

第一个文件在镜像的 /debian-cd/3.1_r4/ 目录中；

后两个文件在 /debian/dists/Debian3.1r4/main/installer-i386/current/images/hd-media/ 目录中。

2. 安装 Grub4DOS

下载 Grub for DOS，按提示安装到 Windows 的 C: 盘。实际上只需把二进制文件 grldr 拷贝到 C: 盘根目录。

编辑 C:/boot.ini ，添加：

C:\GRLDR="Start GRUB"

3. 安装基本系统

重启，进入 Grub 启动菜单，选择 Boot Grub，在 Grub 命令行依次输入以下三行：

grub> kernel (hd0,0)/debian/vmlinux root=/dev/ram \
> ramdisk_size=512000 devfs=mount,all
grub> initrd (hd0,0)/debian/initrd.gz
grub> boot

即开始安装基本系统。

注：

A. 分区基本原则：

必须有主分区 / 和 swap，用户目录 /home 最好单独分区，如果用来做数据库或服务器，分区应当更细；
swap 分区的大小：当内存小于 256M 时，swap 分区大小为内存大小的二倍；当内存大于 512M 时，分给 swap 分区约 512M。

B. 桌面环境及其它软件包

在安装基本系统时，按提示设置好网络和 sources.list ，安装好基本系统以后，用 APT 安装桌面系统及其它软件包。
