Hi, Sorry, I don't have the soruces with me right now, so I can't be exact, but I'll check next week. You need to have a root disk (floppy or hdd), with /etc/init and stuff. To do this, first compile unix with the "built in shell". Check te Makefile for the #define! Also set the root device in the kernel (floppy or hdd). Make a floppy or hdd (be careful with the sector numbers, mkfs works with absolute sectors, so it's easy to overwrite another partition) with the dos based mkfs. Start the kernel with built in shell. It should create /dev/tty automatically, and then you can populate the rest of the /dev directory. There is a tool (sorry, I don't remenber the names, but check the source) to transfer files, via an ather floppy, which is a horrible kludge, first you write one file on it using one of the utilities, then start the kernel, and using one of the built in commands you write it into the filesystem. This has to be done one-by-one. You can exit the kernel via shift-escape (?), but do a sync before. Once you have the root floppy, recompile the kernel without the shell. Now about the bug: I think I broke something in the inode code (I once wanted to rewrite the code in ansi c, and then lost the original), so currently, it won't mount the root fs. With plenty of printf's in the kernel it's possible to debug :-). Regards, Szabolcs
