In order to make a digital picture frame with an IA-1 and Damn Small Linux, there is one major constraint. No matter how big your CF card is, there is only 64 megs of ram in the device. This means, if you put a complete image of Damn Small Linux, and add something small, like feh, weighing in at less than 500k IIRC, the device will crash on boot, complaining about lack of ram.
That makes this process about eleventeen times more complex, but still within the realm of possibity. Even easier if you have a guide, you know, something like this.
My first step was to make a feh extension for Damn Small Linux. This is unbelievably easy. I did this on my main workstation, booted into Damn Small Linux. First, I enabled apt through the fluxbox menu with Apps > Tools > Enable Apt. Then I started a root console and installed feh with
apt-get install feh. I closed my root console, and opened a user console, and converted the feh debian package to a feh dsl package with
/usr/bin/deb2dsl. I named the package feh.dsl, made the MyDSL menu name feh, and entered /usr/bin/feh as the location path. I then had a feh.dsl extension in my home directory. I copied it to a thumbdrive, and booted my IA-1 with it. As you know, this crashed on boot. I booted my computer with it. It loaded fine. This meant the error that meant “Out of RAM” really meant it.
So my next step was to lighten up Damn Small Linux, and make it Damn Smaller Linux. This means you have to enter the world of remastering. This has to be done on a computer with more ram than your IA-1.
Following the basic idea inside of ReMastering HOWTO for DSL, also newbies and other enthusiasts we burn a copy of Damn Small Linux on to CD, and reboot our computer.
Mount an open directory off your hard drive.
Make needed directories.
Copy needed files to the remastering directories
cp -Rp /cdrom/boot /mnt/hda3/newcd
cp -Rp /cdrom/lost+found /mnt/hda3/newcd
cp -Rp /cdrom/index.html /mnt/hda3/newcd
cp -p /mnt/hda3/home/wolf/feh.dsl /mnt/hda3/newcd
Copy the sources to the right directory.
cp -Rp /KNOPPIX/* /mnt/hda3/home/wolf/dsl/source
cp -Rp /KNOPPIX/.bash_profile /mnt/hda3/home/wolf/dsl/source
At this point, remove firefox from /mnt/hda3/home/wolf/dsl/source/. This will free up over 17 megs of space. I did this with some nasty bash. I believe it was
find /mnt/hda3/home/wolf/dsl/source | grep firefox and then judiciously removing the firefox directories and executable. To be pretty, you have to then remove the desktop link and menu entry.
Create the compressed image.
mkisofs -R /mnt/hda3/home/wolf/dsl/source | create_compressed_fs - 65536 > /mnt/hda3/home/wolf/dsl/newcd/KNOPPIX/KNOPPIX
Create the iso:
mkisofs -no-pad -l -r -J -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o mydsl.iso newcd
