Yes, you're right, it looks scary (though I already reset a BIOS about 2 months ago... And the machine returned to life...). What I wanted was to store the IP address of a diskless machine (live- CD based) when no DHCP server is available. I get it as input from the user in the first boot, but I can't store it in the network, because I can't access the network without this IP. And I don't want to depend on an extra flash. Is there any alternative? (I heard that all of the NIC cards have CMOS too).
