linux 8??????
There ain't no such thing.
We need your distribution (Red Hat Slackware SuSe, Mandrake, etc.) and the release version.
# What is the distribution
cat /etc/.product
cat /etc/.issue
cat /etc/issue
cat /etc/issue.net
sysinfo
I understand that SiS video isn't supported so svga is the best you can hope for.
