Yes; you will need to ROM the text portion of the kernel image, and ROM-with-load-to-RAM-on-startup the data. The kernel load address will need to be the ROM address after the segment register load. This is typical configuration for any ROM'able kernel for any system. > What should I do with the swap space area ? Just don't have one.

Yes. > If there is a one, can I assign the swap space to a file which > resides in the virtual file system ? No. The RAM disk is subtracted from the available virtual memory (which is the available real memory + the available swap). In this case, there would be no difference between real memory and the RAM disk. It probably wouldn't work anyway -- it would be recursive. > I have no intention to build a web box.

We do this locally, though we use a netboot to do it instead of using a floppy.
