Boot problem with firewall (iptables)

Hi; I have Suse 8.0 pro , last 2 weeks i can't boot. After kernel loaded and hardisks detected when Suse want to detect firewall (initial) [original sentence is: Starting personal-firewall (initial) ] Suse freezes and nothing happen. I can type console but boot sequence doesn't continue. How can I rescue system ? I think initial firewall is iptables. Thanks in advance for your assistance. paradoxe
