Keyboards are often tailored to the characters used in a language. Select a layout that conforms to the keyboard you are using, or select something close if the keyboard layout you want isn't represented. Once the system installation is complete, you'll be able to select a keyboard layout from a wider range of choices (run kbdconfig as root after you have completed the installation). Move the highlight to the keyboard selection you desire and press &enterkey;. Use the arrow keys to move the highlight — they are in the same place in all national language keyboard layouts, so they are independent of the keyboard configuration. An 'extended' keyboard is one with F1 through F10 keys along the top row. On DECstations there is currently no loadable keymap available, so you have to skip the keyboard selection and keep the default kernel keymap (LK201 US). This may change in the future as it depends on further Linux/MIPS kernel development. There are two keyboard layouts for US keyboards; the qwerty/mac-usb-us (Apple USB) layout will place the Alt function on the Command/Apple key (in the keyboard position next to the space key similar to Alt on PC keyboards), while the qwerty/us (Standard) layout will place the Alt function on the Option key (engraved with 'alt' on most Mac keyboards). In other respects the two layouts are similar. If you are installing on a system that has a Sun USB keyboard and have booted the installer with the default 2.4 kernel, the keyboard will not be identified correctly by the installation system. The installer will show you a list of Sun type keymaps to choose from, but selecting one of these will result in a non-working keyboard. If you are installing with the 2.6 kernel, there is no problem. To get a working keyboard, you should boot the installer with parameter priority=medium. When you get to keyboard selection If you are installing at default priority you should use the Go Back button to return to the installer menu when you are shown the list of Sun type keymaps. , choose No keyboard to configure if you have a keyboard with an American (US) layout, or choose USB keyboard if you have a keyboard with a localized layout. Selecting No keyboard to configure will leave the kernel keymap in place, which is correct for US keyboards.
