They just changed the name of the file ! It is section 10.16

Well I had it set to "auto" too!
One thing I maybe failed to mention is that my disk's 1232 cylinders are
correctly recognized by the bios. Yet fdisk will be willing to work on
cylinders above 1024 ONLY if LBA mode is disabled in the BIOS. And then
lilo will work ONLY if LBA mode is set on again...
My BIOS (AMI simple setup utility v.1.19 (1998) and motherboard (1999)
are not that antic anyway !

This makes me think of a quite different issue: I am not eager to
upgrade the dist since I did quite a bit of upgrading on my 5.2.
I don't have a clear vision of the benefits in upgrading the whole
thing.
Thanks for your interest,
