   Question:: I have a local harddisk drive connected to my target
      board. Can I install the ELDK on it and run it like a standard
      Linux distribution?

   Answer:: Yes, this is possible. It requires only minor
      adjustments. The following example assumes you are using a SCSI
      disk drive, but the same can be done with standard SATA or PATA
      drives, too:
      1 Boot the target with root file system over NFS.
      1 Create the necessary partitions on your disk drive:
        you need at last a swap partition and a file system partition.
        <verbatim>
bash-3.00# fdisk -l 

Disk /dev/sda: 36.9 GB, 36951490048 bytes
64 heads, 32 sectors/track, 35239 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         978     1001456   82  Linux swap / Solaris
/dev/sda2             979       12423    11719680   83  Linux
/dev/sda3           12424       23868    11719680   83  Linux
/dev/sda4           23869       35239    11643904   83  Linux
        </verbatim>
      1 Format the partititons:
        <verbatim>
bash-3.00# mkswap /dev/sda1
bash-3.00# mke2fs -j -m1 /dev/sda2
        </verbatim>
      1 Mount the file system:
        <verbatim>
bash-3.00# mount /dev/sda2 /mnt
        </verbatim>
      1 Copy the content of the (NFS) root file system into the mounted file
        system:
   <verbatim>
bash-3.00# tar --one-file-system -c -f - / | ( cd /mnt ; tar xpf - )
        </verbatim>
      1 Adjust ==/etc/fstab== for the disk file system:
        <verbatim>
bash-3.00# vi /mnt/etc/fstab
bash-3.00# cat /mnt/etc/fstab
/dev/sda2       /               ext3    defaults        1 1
/dev/sda1       swap            swap    defaults        0 0
proc            /proc           proc    defaults        0 0
sysfs           /sys            sysfs   defaults        0 0
        </verbatim>
      1 Adjust ==/etc/rc.sysinit== for running from local disk; remove the
        following comments:
   <verbatim>
bash-3.00# diff -u /mnt/etc/rc.sysinit.ORIG /mnt/etc/rc.sysinit
