Today I needed to install SmartOS and OpenBSD onto an old server whose dvdrom is not working. Because dvdrom is not working, I didnt have much options to install an iso then pxe booting. According to instructions on this site, I set up an ubuntu tftp and pxe server and managed to start live version of SmartOS on that server. But I realised after that I cant install SmartOS that way. It was just for booting as far as I understood. So I changed my way and installed OpenBSD by pxeing. OpenBSD is installed with using file sets on remote ftp sites. Actually I made a local http server to broadcast those sets but because of ethernet problems on that old server, I couldnt manage to connect to local http server. They were some strange ethernet problems. But at last I managed to connect to a remote ftp server and loaded these sets smoothly.
I learned that iPXE is a powerfull opensource pxe program by this journey.
