5.9 Light comes with two slightly different kernels, "sata" (default) and "ide". You can choose which one when you to use when booting from the CD. To use the IDE kernel to boot your installed system, use "ide root=/dev/sda1 ro".
Try to edit fstab (make a backup first) to reference "hdXX" instead of "sdXX", and boot to the secondary kernel. If it works better than the other, then edit /etc/lilo.conf to make "188.8.131.52" the default kernel (change the line that says "default = linux"), then run command "lilo" as root.
