Sapariya> Any suggestions will be of great help. Intel has (had?) an EFI implementation for IA-32 machines. You put that on a floppy disk, boot the system with it, and you get an EFI prompt (nshell prompt, to be exact). From there you can launch your own EFI programs. The GNU EFI support has support for building IA-32 EFI applications, but it hasn't been tested in a while (not since I got IA-64 hw to play with, to be exact). However, provided you have a toolchain that builds valid IA-64 EFI applications, I think it's very likely that the IA-32 side will also work, so it may be worth a try. Hope this helps, --david
