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 PATHbash#
cat /etc/mtabbash#
local_fsbash#
cat /etc/mtabbash#
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 PATHbash#
cat /etc/mtabbash#
local_fs /dev/ram0: clean 74/1024 files 3178/4096 blocks Remounting / as read-write. Mounting local filesystems.bash#

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/fd0bash#
fsck /dev/fd0bash#
mount /dev/fd0 /homebash#
mkdir /home/floydbash#
cd /home/floydbash#
echo "Goodbye cruel world." > goodbye.txtbash#
cat goodbye.txt
