+USB braille displays should be automatically detected. A textual version
+of the installer will then be automatically selected, and support for the
+braille display will be automatically installed on the target system.
+You can thus just press &enterkey; at the boot menu.
+Once <classname>brltty</classname> is started, you can choose a braille

+Serial braille displays cannot safely be automatically detected
+(since that may damage some of them). You thus need to append the
+<userinput>brltty=<replaceable>driver</replaceable>,<replaceable>port</replaceable>,<replaceable>table</replaceable></userinput>
+boot parameter to tell <classname>brltty</classname> which driver it
+should use. <replaceable>driver</replaceable> should be replaced by the

+<replaceable>device</replaceable> should be replaced by the name of the
+serial port the display is connected to, <userinput>ttyS0</userinput> is

+table to be used (see the <ulink url="&url-brltty-table-codes;">table code

+Support for hardware speech synthesis devices is available only alongside
+support for graphical installer. You thus need to select the

+Hardware speech synthesis devices cannot be automatically detected. You

+<userinput>speakup.synth=<replaceable>driver</replaceable></userinput>
+boot parameter to tell <classname>speakup</classname> which driver it should

+<para>
+
+Some accessibility devices are actual boards that are plugged inside the
+machine and that read text directly from the video memory. To get them
+to work framebuffer support must be disabled by using the
+<userinput>fb=false</userinput> boot parameter. This will however reduce
+the number of available languages.

+For users with low vision, the installer can use a high-contrast
+theme that makes it more readable. To enable it, append the
+<userinput>theme=dark</userinput> boot parameter.
