down load the latest ISO then burn it to a cd,(make sure that you burn it as an ISO) format a floppy disk in fat 32. need 2 nic's, "check hardware compatibility first". put cd and floppy in system, and boot. dont connect the ethernet cables yet. let system boot up "cd rom as first boot drive". then the rest.....well the disk will walk ya through it. It is really simple and user friendly, and it is a darn good firewall. ......... If ya have room for more ISA slots you can add more nic cards and it will be a router/firewall. .................. O-yea the blank floppy is for system configuration. thats where the system saves the changes! But read the link that Akhilles provided. Good luck!
