This is going to be a really technical question. I hope someone can answer.

I need to install FreeBSD 4.5 on a system that has no CD-ROM drive and no floppy drive.

The system has a PXE enabled network card.

What I want to do is download an MS-DOS virtual floppy image (via PXE) to the system. I already have this part working. After I download the virtual dos floppy image to the system, I need to run something like a loadlin.exe program (but one that works for FreeBSD). Loadlin is a DOS program that lets you load a linux kernel image from an DOS system. I am hoping there is something like this that will work for FreeBSD kernels.

So the "loadlin" program will execute the kernel that FreeBSD needs to startup it's install program. And then once FreeBSD's install program is up and running, I have an FTP server on another computer that has the CD-ROM files.

So, first I need a loadlin type program that will allow me to boot a FreeBSD kernel from an MS-DOS boot floppy. Second, I need a FreeBSD kernel image that starts up the FreeBSD installer.
