I checked with the latest build of the Ubuntu CD and I saw the same problem. I saw that the list of the keymaps is in the /isolinux/bootlogo file on the cdrom. Switzerland is currently de_CH when it could also be fr_CH.
** Changed in: syslinux (Ubuntu) Status: Unconfirmed => Confirmed -- Only one keymap is available for Switzerland https://launchpad.net/bugs/67355 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
