Customizing SCLive using Linux command lines

July 24, 2006 Leave a comment

The SystemC liveCD is based on the Linux operating system. As a result the provided ISO file can easily customized with just a few command lines. This how-to will detail the steps required to mount the SCLive ISO file, modify it to fit your own requirements and eventually, recreate a new ISO file containing your alterations.

  • The first step is to mount the original SCLive-x.x.iso file this can be achieved with the command:

sudo mount -o loop -t iso9660 SCLive-1.0.iso /mnt/loop

  • The next step will be to create a temporary directory and copy the content of /mnt/loop inside it:

mkdir ~/mySCLive

  • We can now move to the temporary directory and copy the content of the ISO in there:

cd ~/mySCLive

sudo mkdir /mnt/loop

sudo cp -r /mnt/loop .

  • We now need to change the permissions to ‘write’:

sudo chmod -R +w *

  • You can now add or remove modules form the temporary directory. Typically you will navigate to the modules directory and add or remove .mo files from here.

cd ~/mySCLive/loop/modules

sudo rm Geany_0_7_1.mo

sudo cp ~/SciTE_1_66.mo .

  • In this example we are replacing the geany IDE with SciTE. These modules can be found at http://www.slax.org/modules.php
  • Once your alterations are done we will need to recreate the ISO file with the following commands:

cd ~/mySCLive/loop
sudo cp -f boot/isolinux.bi_ boot/isolinux.bin

sudo mkisofs -o mySCLive.iso -v -J -R -D -A "mySCLive" -V "mySCLive" \
-no-emul-boot -boot-info-table -boot-load-size 4 \
-b boot/isolinux.bin -c boot/isolinux.boot .

Et Voila. You should now be able the burn the newly created ISO file with your favorite CD burning software or by following one the the how-tos on burning ISO files.

Just a last recommendation, use a CD-RW or even better a virtual environment (See the Virtual Machines how-to) when creating your own ISO image since it usually takes a few iterations before you get it just right.

Using K3b for Customizing SCLive

July 17, 2006 1 comment

This HowTo details the steps to add modules to a SCLive ISO, under its /modules directory.

Note: The original how-to was written by jayseye.

From the main K3b window, pull down the Tools menu, choose Burn CD Image, and navigate to your downloaded SCLive .iso file, by clicking on the blue folder icon, under and to the right of Image to Burn. It may take a minute for the checksum to be confirmed.

Below that, on the Options tab, select the “Verify written data” checkbox to have K3b re-read the CD after it is written.

Then, on the Advanced tab, enable the “Start multisession CD” checkbox. This step is essential to allow re-burning the CD.

Insert a blank CD-R, then click on the Start button in the upper right corner, to begin burning. After the CD is written, K3b will briefly eject it, and then automatically load it again, to begin verification.

When that’s complete, K3b will eject the CD again. If all went well, “Success.” will be reported, to the left of the red KIIIB icon, and you can Close the dialog.

Wait, there’s more! To add modules, re-insert the CD, and choose New Data CD Project, either from the icon in the bottom half of K3b’s main screen, or from its File menu. Then select Import Session… under the Project menu.

At that point the CD’s filesystem is effectively open for adding files via drag-and-drop. It’s also possible to modify and even remove files.

Once you add the desired modules files, Burn the changes to the CD.

Voila !

Using MySLAX Creator

July 17, 2006 12 comments

As you may know, SCLive was created from the brilliant SLAX distribution. As such we can use all the tools meant for SLAX with the SCLive distribution. In this article I will illustrate how to use the MySLAX utility to build your very own version of SCLive.

Note: The original author of this How-to is JKWood.

There are a few things you should know when starting out with MySLAX Creator. First, the operating system files for Slax are contained within files known as modules (*.mo.) These are actually files that contain a whole partition image of the SquashFS compressed filesystem type. It’s comparable to .iso files, which are uncompressed files containing a CDFS filesystem (Compact Disc File System.) As far as I know, there is no way to read from the SquashFS from Windows, although I’m sure it would be easy enough. What I do know is that you can write to SquashFS files by using a program called MySLAX Modulator (henceforth referred to as MSM), which comes with MySLAX Creator (henceforth referred to as MSC).

The nice thing about using MSC is that you don’t have to know how to build your own modules in Windows OR in Slax, as long as you have what you need already available in module form. This is where MSC comes in.

For the purposes of this how-to, we will create a Slax livecd containing the editor Vim. The aim here is to demonstrate the flexibility of MSC, so I’m going to add a module freely available from this website to show how easy it is to add to SCLive. As far as creating new modules from source, pre-rolled software, or packages in other formats such as .tgz or .rpm, that’s beyond the scope of this tutorial.

Now, the first thing you need to have is a copy of MySLAX Creator installed. When MSC comes up, you’ll see a bunch of scrolling text. You can read it or not as you choose, but when you’re ready to start mastering your cd, press the “Next>” button.

Here you’ll be presented with some options. I’m working with the SCLive ISO, so I choose the radio button beside ISO-Default. You can use a preburned cd, but it will be a little slower. In any case, choose where the ISO file is on your hard drive, and press “Mount.” When it’s mounted, you will see several new buttons appear, which we won’t concern ourselves with at this point. At a later point, you can mount your remastered version and choose to burn onto a USB stick.

Pressing “Next>” will net you the “Adding Modules” screen. Now, I save all my modules to the same place as my ISOs, so that I have a list of all my modules that can be installed already at my disposal in the center window. If you don’t see any modules, use the file browser to find where you’ve put your modules.

At this point, we have some choices. Since all we’re doing is adding the vim module, I’ll click that one and then click “Add =>.” In the tab marked “/modules,” my vim module appears. We’re done adding modules, so click “Next>.”

Here, we find the “Remove Modules” screen. You can use this scree to remove existing modules from the SCLive ISO file. For this how-to we will leave the ISO as is. Now, click “Next>.”

Here, we find the “Boot Options” screen. I’ve been running Slax for a while now, and I know some of the cheat codes I use frequently. If you know that you’ll be working with AT LEAST 256 MB of RAM when you use this particular remaster, then I recommend checking “copy2ram.” If you’re not sure about any of these cheatcodes, then don’t select anything; if you need them later, you can always type them in at boot time, and if you want to remaster your remaster later, then you’re free to.

Another click of the “Next>” button brings us to the last screen I generally use, the “Create MySLAX ISO” screen. If you’re satisfied with you configuration so far, you can click “Create ISO.”, and then we wait for the ISO to be created. You’ll see a progress bar and a size estimate of the finished project, and then a dialog informing you that your ISO was successfully created. Click “OK.”

At this point, you have a couple of choices. You can burn the ISO file if want to, but I definitely recommend using rewritable CDs, especially while developing on your customized remaster. I personally quit out of the program and use a program like Nero to write the ISO. Use your favorite burning application, and you’ll have something that you can play with.

Another option is to bypass the CD-burning entirely and put your copy of SCLive on a USB stick. I’ve had good success with this, and it’s very simple. The program will prompt you for your USB stick, at which point the Windows format utility will ask to format it. Unless you have access to the world’s first 8 GB USB stick, the shortcomings of the FAT32 filesystem will not affect us, so let it format. After this, MSC will install SCLive on the stick, and you will have a bootable form of SCLive which will let you save files on it, although you have to specify for it to write to sda_removable (once again, beyond the scope of this tutorial.)

Voila !

Using MagicISO

May 18, 2006 Leave a comment

This article describes how to use MagicISO to create your own version of the SystemC Live Distribution by adding and removing modules from the ISO source file.

MagicISO has ability to create ISO image file. You can directly add/delete/rename files or folder in CD image file(s) with MagicISO.

The following step will describe the procedure for modifying the provided ISO file and recreate a new one.

  1. Download MagicISO from here .
  2. Install the application as instructed.
  3. Run MagicISO and go to the menu File->Open
  4. Navigate the the location of your SCLive-x.x.iso file and load it in.
  5. In the displayed ISO directory structure, you should see a directory called “modules”.
  6. Open the directory called “modules” and add or remove .mo (module) files from there.
  7. Once done go to File->Save to save the new image.
  8. Finaly you can write burn your new ISO file on a CD by following the instructions detailed in How-to Burning ISO Files.

Note: To create your own module files (.mo), take a look at the how-to “Customizing SCLive”.
