Hi,

The memory problem is well known.
The BIOS does not properly report memory above 64Mb.
You can tell LINUX that you have more memory by
editing /etc/lilo.conf and add the "append" line
image=/boot/xxxx
label=xxxx
append="mem=128M"

DO NOT FORGET TO RUN LILO AFTERWARDS!

The disk problem seems to be allso not to unusual, as
there are "artefact barriers at 512Mb, 2Gb and 8Gb".
have a look at:

so long
