mcnlive.loop on ext3

Recommended Posts

Hello all, I have successfully created mcnlive.loop on a ext3 partition on a Compact Flash inserted in my laptop via an PCMCIA adapter.

No way to load it during the MCNlive toronto boot from CD, using the option persist.

Probably because it is not mounted by default, but only after I click on this partition icon of Devices?

Looks like we need to preload the following modules in the initrd:

 

pcmcia_core

pcmcia

rsrc_nonstatic

yenta_socket

ide_cs

 

pilotaviola, have you ever tried to make a remaster-on-the-fly? You would need an ext3 or NTFS partition on the computer where you boot MCNLive.

It is pretty easy.

 

Do you boot from USB or from CD?

 

Let me know if you would like to make a test, I'll tell you how to change two scripts.

Of course I am ready to test!

I never tried remaster on fly because my Thinkpad has just 216mb of ram, I have to use a swap partiton?

I am booting from cd, but I am wondering if after your fixes I could boot from the cf inside the pcmcia...

I'd like better to create by MCC another partition, either ntfs or ext3, on the 4gb compact flash, but I could also use an external usb hard disk with ntfs partitions.

Let me know wich is the best option....

In theorie, with the added kernel modules, you would be able to use a mcnlive.loop on the pcmcia card and you would even be able to boot from the card. Or use a combination: boot from CD the first stage, then continue with the card, like we do with USB.

But unfortunately you don't have enough RAM to make a remaster on the Thinkpad. You could create a swap partition on the card, enable the swap manually (swapon -a), but I am not sure if this is enough for the build process.

 

Give me some time, maybe a week, I'll make you an iso, and give you the download location.

 

But first, can you tell me how the card is seen, I need the device node.

 

Insert the card, and do a:

 

su
fdisk -l

what bootcode in that case? Livecd frompcmcia?

There is something not ok with the partitions on your card. B)

 

Well, it is seen as a normal hard disk. No problem for using a mcnlive.loop persist file.

 

But a problem to implement to _boot_ from it. I'd need to rework the mklivecd scripts to make a cheatcode to boot from a normal HD.

I would like to make a bootcode: pilota

:D

 

Give me some time. I will get back to you.

The code is ready and works, the pcmcia modules are loading ok. But I can't test it. No CF card here. In particular I don't know if detecting the device needs some sleep in the code.

 

Pilota: before I am going to build a final iso for you, could you tell me if you have some special wishes? Things you want me to include, GUI settings changed, uninstalling programs you never use - most likely we will need more than one test, and the smaller the iso is, the easier for me. It takes ages to upload it and wait until the public mirrors are syncing it.

 

The base is: Toronto. Please tell, what you don't need.

 

PS: you help a lot to improve MCNLive, because people will also be able to boot from an internal IDE hard disk, in live mode.

Things you want me to include,

Customisation? That´s wonderful!

:D

I just would like to include Skype and I would like better, if possible, Mozilla firefox than Opera.

Finally, could you put on the background desktop a San Francisco image like this one?

I would avoid the games and the whole office package: I want to load Openoffice in the persitent loop, that´s no limit to the amount of programs loaded there, right?

Thank you, I think for the laptop users to have linux in the flash card, that you can keep inside, unless the usb key, would be alread awesome....

I couldn't include Skype, the license does not allow it.

 

Ok, here we go, here is your pilota.iso

It's only a test version. If we succeed I'll make you an iso with OpenOffice included, because OO is just too much for a persistent image, for my taste :-)

 

I would like to ask you to do the following steps. They are necessary to create a good testcase.

 

1. Please fix your CF card. The partition table is screwed.

In MCC, the menu for mounting and formatting. Please try to erase all partitions! Not only reformat it, erase it.

Then click on: toggle to expert mode. Create a new primary partition, filesystem FAT32. Make it ~ 600 MB or more.

In the input field 'where to mount' delete the entries, it should be empty.

The base system will go onto it. It has to be FAT. You can make it bigger if you want. Format the partition - it is a second step, a button on the left.

Click on the remaining grey area, and create a second partition that fills up the remaining space. Filesystem ext3. Note: check the box that makes it also a primary partition, otherwise MDV will make an extended and inside it a logical, diskdrake is a little bit odd. Mount point: empty the field. Format the partition.

Confirm everything. Close diskdrake.

 

2. Control now the partitions:

 

su
fdisk -l

 

And please post the result here. I'd like to see how the CF card looks now. If it is still odd, we need to wipe the partition table clean on command line.

 

3. Download the iso and burn it on a CD ...

The new CD has 2 new menu entreis on the first screen: Boot from PCMCIA and Boot from PCMCIA with persist.

If your CF card is ok, please boot from the CD, but don't use these new menu entries. Just boot the default!! But have the CF card inserted before you boot.

After you booted sucessfully, run: mount

Are the partitions mounted?

If yes, run the wizard: Create persistent loop, choose ON EXT3, and make a loop file. A small one will do for a test.
