1)do:
Code:
ls -l /
and examine the output. Does vmlinuz exist? If so what is it? Is it a file or is it a symbolic link? If it is a link, where does it point?

2)Boot block is also known as the MBR (master boot record) and is first 512 bytes of /dev/hda and contains the partition table.

3)In most cases, a CDROM disc must be mounted before reading. So first place the CD in the drive. Next find out where the drive gets mounted. It may be mounted on /cdrom or /mnt/cdrom or /media/cdrom. Check /etc/fstab for mount information:
Code:
cat /etc/fstab
You might see output like:
Code:
james@dualcrush:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/hda8       /               ext3    defaults,errors=remount-ro 0       1
/dev/hda3       /mnt/oldir      ext3    defaults 0       1
/dev/hda5       none            swap    sw              0       0
/dev/hda7       none            swap    sw              0       0
/dev/hdc        /media/cdrom    iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0
/dev/hde1       /mnt/storage1   ext3    defaults        0       1
/dev/hda6       /home           ext3    defaults        0       1
/dev/hde2       /mnt/storage2   ext3    defaults        0       1
/dev/hdg1       /mnt/storage3   ext3    defaults        0       1
It is this line
Code:
/dev/hdc        /media/cdrom   iso9660 ro,user,noauto  0       0
that tells the system how to mount a CDROM disc. To mount it (you may need to be root user):
Code:
mount /media/cdrom
Then read it:
Code:
ls /media/cdrom
