I have done an install, but I have understood : I have forgotten to say : I do
not boot with the "standard" GENERIC kernel!
I thought that the NetBSD Install ISO CD-ROM provided the standard GENERIC
kernel, but it is another kernel!
Since my computer can not directly boot on the big hard disk drive (40 GB)
because of the BIOS, I use the NetBSD Install ISO CD-ROM to boot and then use
the "boot -a" at the prompt.

I am sorry for all the inconveniences!

Thanks,

Sylvain.
