The most interesting files are here
[anatol at archie ~]$ ls -l /boot/syslinux/ldlinux.*
-rw-r--r-- 1 root root 122044 May 15 08:07 /boot/syslinux/ldlinux.c32
-r--r--r-- 1 root root  67072 May 15 08:07 /boot/syslinux/ldlinux.sys

ldlibyx.sys is slightly bigger than 64k, does it indicate the problem
in the newer syslinux?
