Start the system using the following procedure:
Boot the PC using the floppy labeled "boot disk".
At the grub> prompt, type the usual kernel and boot commands, but without the rw parameter this time. In other words, type kernel (fd0)/boot/vmlinuz init=/bin/sh root=/dev/fd0 load_ramdisk=1 prompt_ramdisk=1, press Enter then type boot and press Enter.
Put in the recently created root disk when prompted.
The output should resemble the example below:
GNU GRUB version 0.95 grub> kernel (fd0)/boot/vmlinuz init=/bin/sh root=/dev/fd0 load_ramdisk=1 prompt_ramdisk=1 [Linux-bzImage, setup=0xc00, size=0xce29b] grub> boot Linux version 2.4.26 .. .. [various kernel messages] .. VFS: Insert root floppy disk to be loaded into RAM disk and press ENTER RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem) readonly. Freeing unused kernel memory: 178k freed # _ |
Run the script by typing the following commands at the shell prompt:
bash# PATH=/sbin:/bin:/etc/init.d ; export PATH bash# cat /etc/mtab bash# local_fs bash# cat /etc/mtab bash# df |
If everything is working properly, then the screen output should look something like the example below.
bash# PATH=/sbin:/bin:/etc/init.d ; export PATH bash# cat /etc/mtab bash# local_fs /dev/ram0: clean 74/1024 files 3178/4096 blocks Remounting / as read-write.

Procure a blank floppy disk and label it as "home". Remove the root disk floppy and insert the "home" diskette. Type the following commands:
bash# mkfs -t ext2 /dev/fd0 bash# fsck /dev/fd0 bash# mount /dev/fd0 /home bash# mkdir /home/floyd bash# cd /home/floyd bash# echo "Goodbye cruel world." > goodbye.txt bash# cat goodbye.txt |
