keyboardproblem on Imac DV 400Mhz

[Erik Boelens]

I installed YDL 4.0 (in dualboot with OS9) on my Imac DV 400Mhz without problems. It is an original Imac DV with original keyboard and mous. Nothing else (except the etthernetplug) is connected.
The keyboard must be Belgium latin 1. (azerty) that's also ok .
The only strange thing (shit) is I don't found  '@' the 'at' key on my keyboard . It is now ² !! Also the numeric keypad (right) on the keyboard  isn't work !!

I didn't find a simple solution on the Internet . Therefore I posted my question here.

Anyone a solution for this problem  ? 

maybe its better that I install YDG 4.0 again ?  its yet now possible
 
Thanks for youre time,

Vriendelijk groeten,
