<h3> FAQ </h3>
|

|
<ul>
|
|
|
|
<li> <b> Did you write this? </b>
|
|
|
|
<p>
|
|
Well, not really. Its related to <a href="http://psilinux.org/">Psilinux</a>
|
|
which is a project to port linux to Psions.
|
|
When I started, the port to the Revo was pretty much
|
|
complete, but no decent distribution existed for it (though there were
|
|
some for the Revo+).
|
|
The focus of Psilinux is on the 5MX, so
|
|
I put this distribution together to better support the Revo.

|
<li> <b> Can I keep all my existing files in EPOC while I try linux? </b>
|
|
|
|
<p>
|
|
Any files on your palmtop will be lost when you boot linux. It is advised
|
|
that you make backups of any essential files before you install. You will
|
|
need quite a bit of free space for the install, so you may have to delete
|
|
some files to install.
|
|
</p>
|
|
|
|
<li> <b> How can I change virtual terminal? </b>
|
|
|
|
<p>
|
|
The 'menu' key is generally the same as the 'alt' key on PC
|
|
keyboards. You can switch console by pressing menu-1,2,3 etc.
|
|
Similarly, pressing ctrl-menu-backspace equates to ctrl-alt-del
|
|
and will cause init to reboot the system.
|
|
</p>
|
|
|
|
<p>
|
|
Console 1 provides a default shell, you can start extra shells on
|
|
consoles 2-5. Consoles 9 and 10 show the syslog output and kernel
|
|
messages.

<li> <b> How do I type a pipe (|) ? </b>
|
|
|
|
<p>
|
|
Fn-T.
|
|
</p>
|
|
|
|
<li> <b> You always run as root! Dont you know this is bad practice? </b>
|
|
|
|
<p>
|
|
Maybe on desktop/server machines, but this is a PDA. I decided it was
|
|
pointless to bother with multiple users on a palmtop. If you damage
|
|
the system, you can simply install it again fairly quickly.
|
|
</p>
|
|
|
|
<li> <b> Why does the filesystem have a peculiar layout? </b>
|
|
|
|
<p>
|
|
I wanted to keep the filesystem simple so the layout is slightly different to
|
|
a normal linux distribution. I have tried to keep it generally similar to
|
|
the usual layout, however.
|
|
</p>

|
|
|
<li> <b> How do I start PicoGUI? </b>
|
|
|
|
<p>
|
|
From the console, type 'P'. This should automatically start PicoGUI.
|
|
</p>
|
|
|
|
<li> <b> How do I change the PicoGUI theme? </b>
|
|
|
|
<p>
|
|
Edit /etc/pgserver.conf and change the themes= line. There are several
|
|
themes to choose from in /pgui/themes.
|
|
</p>
|
|
|
|
<li> <b> How can I set up a serial connection to my desktop linux machine? </b>
|
|
|
|
<p>
|
|
There is a copy of pppd included which you can use to set up a PPP link
|
|
if you wish. However, I usually use the simpler SLIP protocol.
|
|
</p>
|
|
|
|
<p>
|
|
Firstly, on your desktop machine (you need SLIP support in the kernel
|
|
or the SLIP kernel modules loaded), execute the following commands as
|
|
root:
|
|
</p>
|
|
|
|
<pre>
|
|
slattach -s 115200 /dev/ttyS0 &
|
|
ifconfig sl0 10.0.2.1 pointopoint 10.0.2.2
|
|
</pre>
|
|
|
|
<p>
|
|
(This assumes the revo cradle is on COM1, substitute ttyS0 for your
|
|
serial port otherwise)
|
|
</p>
|
|
|
|
<p>
|
|
Next, on the Revo, simply execute /bin/connect. This performs similar
|
|
commands to the ones above to set up the link on the Revo side.
|
|
Hopefully, if the link is running you should be able to test the link
|
|
by pinging the revo (ip 10.0.2.2) from the desktop machine. You can
|
|
perform simple transfers between the desktop and revo using netcat
|
|
(nc).
|
|
</p>
|
|
|
|
<li> <b> Shouldnt this be called GNU/Linux? </b>
|
|
<p>
|
|
Actually, no. The argument for GNU/Linux is that most linux systems
|
|
are a modified version of the GNU system which has been around for
|
|
longer than linux has. However, Revol uses embedded versions of
|
|
the standard parts of the operating system normally provided
|
|
by GNU tools (uclibc instead of glibc, busybox instead of the GNU
|
|
fileutils etc). So Revol is a non-GNU linux system and it would be
|
|
incorrect to call it GNU/Linux.
