Hi folks. I’ve been trying for a few years to find some time to put together a computer to be a firewall/router/NTP server. I ran across a OpenBSD CD bootable firewall system. I had to try it out because I love OpenBSD, best Unix distribution out in my opinion. So while fixing another system that was infected with endless virus’ and sypware while waiting I started piecing together the system. Most of the computer system was done just had to add two NICs, video card, CD-ROM drive and a 3.5″ floppy drive. I burnt the ISO of the OpenBSD CD bootable firewall system and placed a floppy into the drive. I set the bios to boot from CD at startup but nothing happens. I’ve tried three times on three different machines. I’m not sure what I could possibly be doing wrong. I really want to get this to work due the fact that this is the only specific OpenBSD focused CD bootable firewall that I know of. But it’s not working so if anyone has any suggestions or can recommend another alternative that runs via CD and 3.5″ floppy let me know.
