Debian 安装程序支持使用多个前端提出问题，可访问性各有不同：特别是 text 使用纯文本，而 newt 使用基于文本的对话框。可以在启动提示符下进行选择，请参见第 5.3.2 节 “Debian 安装程序的参数”中的 DEBIAN_FRONTEND 文档。

一些辅助设备实际上是插入计算机里面的板卡，它们直接从显存里面读取字符。要让它们工作，需要使用引导参数 fb=false 禁止使用 framebuffer。然而这会减少可用语言的数量。

For users with low vision, the installer can use a high-contrast color theme that makes it more readable. To enable it, you can use the “Accessible high contrast” entry from the boot screen with the c shortcut, or append the theme=dark boot parameter.

对于低视力的用户，图形安装程序有非常基本的缩放支持：控件++和Control+-快捷键，用于增减字体大小。

Expert, Rescue, and Automated installation choices are also available with accessibility support. To access them, one has to first enter the “Advanced options” submenu from the boot menu by typing a. When using a BIOS system (the boot menu will have beeped only once), this has to be followed by Enter ; for UEFI systems (the boot menu will have beeped twice) that must not be done. Then, to enable speech synthesis, s can optionally be pressed (followed again by Enter on BIOS systems but not on UEFI systems). From there, various shortcuts can be used: x for expert installation, r for rescue mode, or a for automated installation. Again these need to be followed by Enter when using a BIOS system.

另外，Debian 可以使用预置进行完全自动安装。相关文档参见附录 B, 使用预置自动进行安装。

可在 Debian Accessibility wiki 页面中找到有关已安装系统可访问性的文档。
