I’ve been using Atheros for quite some time, and I’ve always liked the madwifi drivers. They allowed really easy switching into monitor mode, and decent levels of packet injection. However, since I’m mostly in an office now, instead of writing web apps in cafes and trying to score free internet, I don’t really need anything fancy. My gentoo stage 1 (3?) days are over. I use Ubuntu, because I’m lazy, and it mostly works.

My new laptop (well, 1.5 year old laptop now, but still new in my eyes) gave me the option between an Intel card and a Atheros wifi card. I chose the Atheros card; then the ath5k module came out, and life has been turbulent ever since.

In summary: the ath5k driver in the 2.6.28 kernel, which is what Ubuntu 9.04 uses, isn’t as up-to-date as the drivers in compat-wireless. Fancy that… This presents me with the option of compiling a new kernel specifically with it, or just installing compat-wireless. I’m lazy, so…

I’ll get a few basic troubleshooting commands out of the way first. After updating the kernel I kept getting disconnected - it appeared I was associate/disassociating frequently.

# dmesg
...

The steps to resolve are as follows:

1. Make sure you have headers for your current kernel.
2. Make sure you have ability to compile programs.
3. Download and install compat-wireless
4. Unload and load the module.

So, first, use Synapitc to get the latest kernel headers and the ‘build-essential’ packages.

Next, download the compat-wireless package. I needed to use one from a few weeks ago because I received the following error:

You can download a working 2009-09-05 set from orbit-lab.org

# tar -xpjf compat-wireless-2009-09-05.tar.bz2
# cd compat-wireless-2009-09-05
# make
# make install
# make unload
# modprobe ath5k

All done. My variable ping times and random disconnections seem to have been mitigated. Thanks wireless guys!

After writing about compiling a new kernel for the Vortex86DX, I’ve had quite a few people email me asking how I installed Debian in the first place. The installation is actually quite straightforward, but it involved several quirky techniques. After doing another install I decided to keep track of the process of installing Debian 5.0 on my eBox-3300.

The following guide assumes a few things. First, you are currently using Linux and a debian variety (although instructions could be altered if using Windows). Second, your USB shows up as /dev/sdb. Third, your eBox-3300 has the HDD set in Native mode. Forth, you are patient.

1. Download the custom vmlinuz and initrd.gz files from my site. Also, download the custom deb files we’ll use near the end of installation:

http://cdn.kelvinism.com/ebox/vmlinuz
http://cdn.kelvinism.com/ebox/initrd.gz
http://cdn.kelvinism.com/ebox/linux-headers-2.6.29.3-vortex86dx.deb
http://cdn.kelvinism.com/ebox/linux-image-2.6.29.3-vortex86dx.deb

EDIT 16-03-2025: I’ve since removed these files.

2. Download an i386 netinst iso:

http://www.debian.org/CD/netinst/

3. Make sure the USB has an MBR installed:

apt-get install syslinux mtools mbr
install-mbr /dev/sdb

4. Format the device as FAT32 with whatever tool you like.
5. Run syslinux on it:

syslinux /dev/sdb1

6. Mount the USB (or pull it out and plug it in again so it shows up on your desktop), and copy the downloaded vmlinuz, initrd, netinst.iso and deb files onto the USB. There should be a file called ldlinux.sys already; create a file called syslinux.cfg and put the following in it:

default vmlinuz
append initrd=initrd.gz root=/dev/rd/0 devfs=mount,dall rw DEBCONF_PRIORITY=medium

7. Unmount the USB, and put it in your eBox-3300. When the system boots up initially, hit F11. Select your USB device. Depending how you created the MBR it might come up as saying “MBR FA:”. Press “A”. When 1234F comes up, press “1”. Press enter at the SYSLINUX “boot:” screen.
8. Proceed as normal through the menu. It will search for an ISO image, and should detect the netinst image you inserted earlier. When you get to the “Load installer components” section, it will complain about no kernel modules found. Select YES. On the next screen you shouldn’t need to load any components, so hit continue. Proceed as normal.
9. If you are ever asked about starting PC card services, hit NO. Proceed as normal.
10. Eventually you will hit a screen that says LVM is not available, hit CONTINUE. Proceed as normal.
11. Near the end it will toss up a list of available kernels. Select either, it shouldn’t matter. When you are allowed to select drivers to include in the initrd, select TARGETED. Proceed as normal.
12. You might get to a point where it says Install GRUB boot loader on a hard disk. This will fail. That’s ok, just skip it and select “continue without boot loader”.
13. You will end up on the “Finish the installation” menu. DO NOT finish! We now need to swap out the current kernel with one that works. Scroll down and select “Execute a shell”. Press CONTINUE. Try these steps when the shell prompt appears:

cd hd-media
cp *.deb /target/usr/src/
cp vmlinuz /target/boot/vmlinuz-2.6.26-2.486
cp initrd.gz /target/boot/
cd /target/boot
gunzip initrd.gz
mv initrd initrd.img-2.6.26-2-486
reboot

Your system will now reboot, and it should actually boot correctly. However, you’re using a kernel that doesn’t have any headers or modules, which means you can’t activate anything. Once the box boots up, login and install the included custom kernels:

cd /usr/src
dpkg -i linux-image-2.6.29.3-vortex86dx.deb
dpkg -i linux-headers-2.6.29.3-vortex86dx.deb
reboot

Once the system comes back up, you should be running a spiffy 2.6.29 kernel, with the ability to add modules.

You may want to follow the tuning section from the MicroClient page on Google Groups. I also modified my fstab file to help reduce wear on the CF card:

tmpfs /var/run tmpfs defaults,noatime 0 0
tmpfs /var/lock tmpfs defaults,noatime 0 0
tmpfs /var/tmp tmpfs defaults,noatime 0 0

Contribution 1: Francois Fleuret emailed through a kind reminder that the qemu-onto-SD card method is a viable option. So, if you want to go the SD route, and have an SD reader, this might be what you’re after!

Basically, install Debian on a SD card with qemu (start qemu with the
install disk iso as cdrom and the SD card as hda), while you are still
in qemu, download and install the kernel deb file

ftp://ftp.icop.com.tw/upload/Shawn/linux-image-2.6.27.9-vortex86dx_2.6.27.9-vortex86dx_i386.deb

then quit qemu, put the SD card in the box and reboot. You are done!

EDIT 16-03-2025: I have since removed these files.

If you want the source file for the above kernels, you can get it from here: 2.6.29-3 source. I recently recompiled the kernel with some extra modules enabled (e.g. ecryptfs), so if you would like to try a newer kernel, you can download my updated kernels too:

http://cdn.kelvinism.com/ebox/linux-headers-2.6.30.4-vortex86dx.deb
http://cdn.kelvinism.com/ebox/linux-image-2.6.30.4-vortex86dx_2.6.30.4.deb

EDIT 16-03-2025: I have since removed these files.

Contribution 2: Trent L has also recompiled a 2.6.28 kernel with wireless extensions built into it, which is what was needed for his wireless card. He has kindly allowed me to distribute them; you can find them here:

http://cdn.kelvinism.com/ebox/linux-source-2.6.28.10_vortex86dx.deb
http://cdn.kelvinism.com/ebox/linux-image-2.6.28.10_vortex86dx.deb
http://cdn.kelvinism.com/ebox/linux-headers-2.6.28.10_vortex86dx.deb
http://cdn.kelvinism.com/ebox/2.6.28.config

EDIT 16-03-2025: I have since removed these files.

Contribution 3: If you have the ebox-3310, you can still read through this, but you may also want to see a suggested installation method and kernels from Stefan.

Contribution 4: Alexandru T. sent through some instructions directly received from ICOP. I’ve added another page with the details. Thanks Alex!

Contribution 5:: Rainbow sent through the solution if your kernel panics with:

it report "kernel bug at fs/buffer.c 1864" and system go mad, even
> "halt" "reboot" take no effect.

Rainbow reported that:

this issue cause by an error Vcore, 0.90v refered by datasheet, and it should be above 0.97.

Contribution 6:: Bob’s also sent through his config file.

Contribution 7: Bob A. has sent through some resources about a special ISO specific for the ebox. It has been added to another page.

Update: I’ve needed to recompile a new Lenny vortex86dx-enabled kernel for 2.6.31.5: image, headers, source and config.

Update: I’ve written up a short tutorial on the method I used to install Debian 5.0 on this device.

A few months ago I purchased the eBox-3300 from WDL Systems. The system was promptly shipped, and there were no “gotchas” from WDL. The little box fit my exact needs - it is small, and built very, very well. I flew back to Australia and, after some trial and error, installed Debian 5.0 on it. For quite some time I was just using the vmlinuz file provided by WDL, which was provided by ICOP (DMP). This worked well, but there were two issues:

1. I couldn’t load any modules (e.g. NFS).
2. I received an annoying email from OSSEC every few hours telling me it couldn’t find modules.dep.

At the end of last week I finally decided to do something about it, and considering this little box is “x86 compliant”, I figured it wouldn’t be too hard to create a new package. It has been several years since I last created a self-compiled Debian-packaged kernel, so I decided to document the process for the next time I do it. These steps are really just a summary - but if you have much Linux experience, they should be enough to guide you. If I’m unclear, just send me an email.

Because the eBox-3300 is embedded, I logically decided to create the package on another system. However, I wanted to maximize the chances of it working, so I installed Debian 5.0 in VirtualBox, updated it, and proceeded.

As a prep, you may need to install ncurses-dev and kernel-package in your build environment.

apt-get install ncurses-dev kernel-package

1. Download latest kernel from: http://www.kernel.org/pub/linux/kernel/v2.6/
2. Download the DMP provided patch/config file for 2.6.27.3, copy it to /usr/src. Alternatively, you can borrow my 2.6.29.3 config Make a backup.
3. Untar kernel, cd into the kernel directory. Issue:

make menuconfig

4. Configure kernel. If you used my config file, a lot of these should already be ticked.

• Load alternative config file, I selected mine as /usr/src/config-2.6.27.9-vortex86dx, or if you downloaded the one from me, use config-2.6.29.3-vortex86dx
• Enable generic x86 support
• Enable Kernel .config support
• Device drivers -> Network -> 10 or 100Mbit -> RDC R6040, set at built in
• Turn off generic IDE support
• Exit, make sure to save the kernel
• Verify .config exists. If it doesn’t, copy the config-2.6.x.x-vortex86dx file to .config

5. Create the kernel debs. In the kernel directory, issue these commands. This will build the kernel image, the headers, and the modules.

make-kpkg --initrd kernel_image kernel_source kernel_headers modules_image

6. Make coffee
7. Copy the debs to your running ebox by sftp (or usb, or whatever is available)
8. Install kernel in eBox-3300

dpkg -i linux-source-2.6.29.3-vortex86dx.deb
dpkg -i linux-headers-2.6.29.3-vortex86dx.deb
dpkg -i linux-image-2.6.29.3-vortex86dx.deb

9. Reboot. If you want my compiled kernel/sources/header .DEBs, just shoot me an email and I’ll make them available.

Summary: My only gripe about this little box was the lack of an easily customizable kernel, but no more. I’m still very happy with this $150 purchase.
