Gentoo installer seems to skip keymap selection

[Zu`]

When I try to install Gentoo 1.1a (boot from 16MB iso cd-rom), the installer seems to skip keymap selection. It simply won't let me choose the correct keymap and advances to the next phase of the installation.

Eventually it comes up with a shell that uses Querty, and I need the Belgium Azerty keymap. Is there a way to change it manually once I'm in the shell?

Basically I'm just asking what file to edit, so I can use the right keymap during installation.

TIA
