==== Description ====
 +

This software for CD remastering is include a lot of DEB-packages (elphel-specific and dependenced), files and scripts. All software is compressed to the .tar.bz2 archive (package size is approx. 26 Mb).

There are two scripts for remastering.

First script (make.sh) is general and started by user. Source code:

Knoppix Live-CD remastering

At present time this software is a beta-testing.

Description

This software for CD remastering is include a lot of DEB-packages (elphel-specific and dependenced), files and scripts. All software is compressed to the .tar.bz2 archive (package size is approx. 26 Mb).

There are two scripts for remastering.

First script (make.sh) is general and started by user. Source code:

exit

System Requirements

You must have:

1. at least 1 GB of FREE RAM+Swap total (e.g. 256M ram, and 750M swap AVAILABLE)

2. 3 GB free on a Linux filesystem (ext2/3, xfs, etc.) formatted disk partition (you must unmount this partition before remastering)

3. Knoppix 4.0.2-2005-09-23 EN

Instruction

2. Boot from the Knoppix CD

3. Unpack archive to the /home/knoppix directory

4. Open a root shell:

Menu: Kmenu->Knoppix->Root Shell

5. Type the following two commands: 


cd /home/knoppix/LiveCD-1.4.3

sh make.sh

6. The remastering script will be started. You must specify the work partition (for example hda1). This partition will be used for remastering Knoppix.

NOTE: This partition MUST be unmounted!

7. Follow the appeared instructions

8. The ELPHIX-1.4.3.ISO image will be placed at the work partition

9. Use the special software (for example, K3B) for writing image to CD
