Im trying to write a bootloader in assembly with TCP/IP protocols built in.

1) It will detect the Network card.
2) it will load a text interface in which the network boot location is specified by the user (ip adress).
3) It will attemt to boot off of the remote computer

I am planning to image a Harddrive with linux and share the image using ftp. i think i may use knoppix disk as the image. the computers the operating system will be put on are 350's w/ 64 megs of ram and a floppy drive (no HD). (the bootloader will be put on a floppy disk and the computer will boot from there. The entire thing will be written in assembler (unless someone has a better idea). The problem is, How do I impliment the TCP/IP protocol in it. I have the bootlader worked out for everything but that... Any help would be great..

have a look at the dox at www.partimage.org and see if imaging via network would suit you.

can't help either way

If you want to be able to boot over the network and don;t want to use partimage (probably the easier solution) then take a look at http://www.rom-o-matic.net/
