fixing initrd boot screen?

Hello,

I installed Knoppix on HDD with the debian-begginer option (autodetect devices on boot) and have a small problem to fix:

at boot time, initrd changes the VGA screen from the 80x25 to one with more columns and lines. Unfortunately, my laptop does not shows all the text now, there are columns and lines outside the screen area. This really bothers me, as I am the console guy...

I did a bit of digging through the FAQ but could not find any of the boot.img, syslinux.cfg, etc.

Is there a way to fix it?
Thanks
a.

Use "vga=normal" as cheatcode - or include it in syslinux.cfg
