214 Welcome to Linux

To get into rescue mode, you’ll need a rescue disk set. These are two diskettes that contain the ﬁles

necessary to boot into rescue mode.

If you elected to make a boot diskette while you were installing Red Hat Linux, you’re halfway there!

The ﬁrst diskette in a rescue disk set is this boot diskette.

Now on to the second diskette. . .

The second diskette is called the rescue diskette. It is produced by writing an image ﬁle onto a diskette.

The image ﬁle is called rescue.img, and is located in the images directory on the ﬁrst Red Hat Linux

CD-ROM.

To gain access to this ﬁle, you’ll ﬁrst need to mount your Red Hat Linux CD-ROM.

Start by inserting the CD-ROM in your system’sCD-ROMdrive.You’ll need to do this while logged

in as root.

Type the following command:

mkdir /mnt/cdrom

Now, type:

mount /dev/cdrom /mnt/cdrom

You may get an error message from the ﬁrst command saying that the ﬁle exists. That’s ﬁne; we

just want to make sure that there is a /mnt/cdrom directory on your system. The second command

should issue an informational message that /dev/cdrom is being mounted read-only.

Please Note: Some systems may not recognize /dev/cdrom.Ifthisisyourcase,you’ll have to

replace /dev/cdrom in the command with the appropriate device name for your CD-ROM.

Next, issue the following command (again, while logged in as root):

cd /mnt/cdrom/images

then type:

to list the contents of the images directory.

You should see a ﬁle named rescue.img. This is the rescue diskette image ﬁle. Next, put a diskette

in your ﬁrst diskette drive, and enter the following command:

dd if=rescue.img of=/dev/fd0 bs=1440k
