That a better explanation ;) (afaik there are some changes from 2.4 to 2.6
driver's implementation and also some paper about the subject, I will see)

>I have never tested a 2.6 kernel on a HP.

Another question: I also try it with 2.4 (32 or 64 bit kernel) running on
a b2k.
But this b2k is equiped with an ide cdrom and when I try to boot a kernel
with builtin pdc driver (2.4 and 2.6), the boot process hung (the green led
of the cdrom stay continuously bright, so it seems a pb of initialization
in the pdc_console driver?. This pb also occurs even if I unplug the cdrom-drive
or remove ide-cdrom driver from kernels. otc kernels boot well with builtin
ide-cdrom driver without pdc_console driver)

Any other idea?

Thanks again,
    Joel
