AWS 控制台里有三种复制 EC2 的方式，区别在于是否携带磁盘数据。

创建 AMI（推荐，完整克隆） — 保留系统盘数据、已安装软件和所有配置。

EC2 控制台选中目标实例 → Actions → Image and templates → Create image。等 AMI 状态变为 available（几分钟到几十分钟），再到 AMIs 页面选中它 → Launch instance from AMI，按需调整 instance type、subnet、Security Group 即可。

Launch More Like This（最快，但不含数据） — 只复制实例规格配置（type、SG、subnet、tags），系统盘是全新的。

Actions → Image and templates → Launch more like this，进入 Launch 页面时配置已预填好，确认启动就行。适合无状态实例，比如用 userdata 初始化的 web server。

Launch Template — 如果原实例之前保存过 Launch Template，可以直接从模板启动。EC2 → Launch Templates → 选模板 → Actions → Launch instance from template。

大多数场景用 AMI，只需要同规格全新系统时用 Launch More Like This。

Steps

1. Install cpupower:

sudo apt install linux-cpupower

2. Edit the init script:

sudo vim /etc/init.d/cpupower
# put the following content into this file
CPUPOWER_START_OPTS="frequency-set -g performance"

3. Enable on boot:

sudo update-rc.d cpupower defaults

4. Apply immediately:

sudo cpupower frequency-set -g performance

5. Verify:

cpupower frequency-info | grep "The governor"

Should output: The governor "performance" may decide which speed to use

Note: MX Linux 25 uses SysVinit.

Run regedit, navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run then remove the line that contains "jusched.exe".

To make DOSBox automatically mount your ~/games folder as the C: drive every time it starts, you can edit the DOSBox configuration file. Here's how to set it up:

Steps:

1. Locate your DOSBox configuration file:

   • On Windows, it's usually found in C:\Users\YourUsername\AppData\Local\DOSBox\dosbox-[version].conf.
   • On macOS/Linux, it's typically found in ~/.dosbox/dosbox-[version].conf.

2. Edit the configuration file: Open the dosbox-[version].conf file with a text editor (e.g., Notepad on Windows or nano on Linux/macOS).

3. Find the [autoexec] section: Scroll down to the very end of the file until you find the [autoexec] section. This is where you can add commands that DOSBox will execute when it starts.

4. Add the mount command: Add the following line to mount your ~/games folder as the C: drive:

   • On Linux/macOS, add:

     mount c ~/games
     

   • On Windows, if you want to mount a specific folder, use the path like this (assuming your folder is in C:\Users\YourUsername\games):

     mount c C:\Users\YourUsername\games
     

   You can also specify different mount points or add other commands, but this one will mount your ~/games directory automatically as C:.

5. Save the file: After adding the mount command, save the configuration file and close the text editor.

6. Start DOSBox: Now, every time you start DOSBox, it will automatically mount the ~/games folder as the C: drive.

Example:

Here’s what the [autoexec] section could look like:

[autoexec]
# Lines in this section will be run at startup.
mount c ~/games
c:
