Follow these steps to boot the system:
Restart the PC with the boot disk in the floppy drive.
grub>prompt appears, type
kernel (fd0)/boot/vmlinuz init=/bin/sh root=/dev/fd0 load_ramdisk=1 prompt_ramdisk=1and press Enter.
After the kernel loads, type
bootand press Enter.
Insert the root disk when prompted.
If all goes well the screen should look something like the example shown below.

Try out a few of BASH's built-in commands to see if things are working properly.
Try out a few other familiar commands.
Notice that only commands internal to BASH actually work and that external commands like ls and mkdir do not work at all. This shortcoming is something that can be addressed in a future phase of the project. For now we should just enjoy the fact that our prototype boot / root diskset works and that it was not all that hard to build.
