You might find the attached email useful -- at least it's a place to start. I
tried to send email the adddress listed in the first message, but no luck.
Incidentally, have you used any PCMCIA devices yet? I'm very seriously
considering buying a 4120 or better, and would like to make sure it can handle
*those* devices correctly before I do so.

<h3> Introduction </h3>
Our laboratory recently bought a Compaq Armada 4120 notebook computer.
This page describes the installation of Linux on it. I only pay attention
to the particular difficulties encountered - look
elsewhere for a complete description of Linux installation.
<p>
What proved extremely helpful was Chris Burghart's
<a href="http://www.atd.ucar.edu/homes/burghart/SENS810.html">;
Linux on the Samsung SENS 810</a> (it seems the Armada is a rather
close copy of the Samsung machine.) Chris Burghart includes many
other tips you might be interested in; I haven't copied all of them
here.
Many thanks to others with similar pages on the <a
href="http://www.cs.utexas.edu/users/kharker/linux-laptop/">;
Linux Laptop Homepage</a>.
<p>
<hr>
<h3> Keeping Windows 95 </h3>
The Armada comes with Windows 95 pre-installed on a single partition
that spans almost the whole hard disk, i.e., there is no free
partition to set up Linux on. That is not a problem if you
do not plan to keep Windows 95 available, in which case you
just use the partition for Linux.
<p>
On the other hand, if you do want to keep Windows 95 available,
then note that Compaq does not supply a Windows 95 CD-ROM
with the computer, which means that if you want to back-up
the Windows 95 installation, you need 31 (thirty-one) diskettes
and... a lot of patience. (I did this, just for safety's sake,
but it was not fun.)
<p>
Next, you could, conceivably, re-partition and re-format the
Windows 95 partition. However, as a less brutal alternative,
you can split the existing Windows 95 partition with Arno
Schaefer's non-destructive partition splitting program
<a href="http://www.student.informatik.th-darmstadt.de/~schaefer/fips.html">;
FIPS</a>. It runs under DOS and is simple to use, so I did, ending
up with two partitions of about 500MB each. (Compaq has put a third
partition of some 4MB at the start of the disk - it seems to contain
various Compaq setup files, so I did not touch it.)
</ul>
<hr>
<h3> Installing Linux </h3>
I installed Slackware 3.0, starting with the <tt>idenet</tt> boot
disk. If you get the CD-ROM expansion unit, you can install the rest
from a CD-ROM. Of course, the kernel should have IDE/ATAPI
CD-ROM support enabled. In our case, the drive showed up as <tt>/dev/hdb</tt>.
<p>
<h4> XFree86 </h4>
I installed the SVGA X server (XF86_SVGA). The VGA16 server works, too,
but there's not much point in using it.
<p>
The Armada 4120 has a Cirrus Logic CL-GD7548 graphics chip. While
this chip is listed among those supported by the SVGA server
(current version 3.2), the support appears broken. However,
the chip can be treated as a CL-GD5428, which <i>is</i> supported by the
server. Here is a copy of our current
<a href="XF86Config"><tt>XF86Config</tt></a>
file (from <tt>/etc/XF86Config</tt>); note that it is set up to
support our Finnish keyboard.
<p>
I have noticed the same occasional 16x1 horizontal glitches
as Chris Burghart. As he says, <tt>xrefresh</tt> fixes the
problem. Another problem is that the <tt>variable</tt> font that
I'm fond of shows up disproportionately large. Perhaps a
new version from XFree86 will solve these problems.
<p>
The mouse is overly sensitive. However, it is so under Windows 95, too,
so this is not XFree86's fault.
<h4> Sound </h4>
Chris Burghart's sound configuration works fine:
<ul>
<li> SoundBlaster
<li> address base: 0x220
<li> IRQ: 10
<li> first (8-bit) DMA slot: 1
<li> second (16-bit) DMA slot: 7
<li> DSP buffer size: 16 Kbytes
</ul>
Some programs, notably RealAudio, will open both the audio in (microphone)
and the audio out (loudspeaker) channels. The speaker output will then feed
back through the mic, and the Armada starts emitting a terrible whine.
Get the <a href="ftp://ftp.funet.fi/pub/Linux/util/sound/snd-kit/snd-util-3.5.tar.gz">;
SoundKit</a> package; it includes a mixer utility that can mute the microphone:
<p>
<tt>armada:~>mixer mic 0</tt>
<h4> PCMCIA Card Services </h4>
The Armada has the typical PCMCIA slot for two type II cards or
one type III one. The first Ethernet card we put in - a D-Link DE-850T -
wouldn't work; indeed, it wouldn't work under Window 95, either
(well, it's not supposed to, as documented in the README file
on D-Link's driver diskette.) It would appear that only D-Link's DE-850
<i>combo</i> card works, the one with both 10Base2 and 10baseT.
In any case, we swapped it for a 3Com 589CS - another combo card - and
that card works just fine.
<p>
The card services are built as modules; get the
<a href="ftp://ftp.funet.fi/pub/mirrors/sunsite.unc.edu/pub/Linux/kernel/pcmcia/pcmcia-cs-2.8.23.tar.gz">;
PCMCIA card services</a> package.
Once again, Chris Burghart's set-up (<a href="http://www.atd.ucar.edu/homes/burghart/config.opts">;
config.opts</a>) did not need changing.
<p>
<h4>Advanced Power Management</h4>
With APM enabled in the kernel (in our case, 2.0.24), things seem
generally to work as they are supposed to. Even hibernation (the contents
of the RAM are written to disk, then restored) works. However, there
are problems that manifest themselves with the keyboard - when resuming
after suspension,
the Armada comes up seemingly not accepting any keyboard
input at all. A trick we've found is to change to another virtual terminal,
then come back to the first one.
<p>
The PCMCIA devices - in our case, the Ethernet card - do not seem
much bothered by suspension (this is contrary to Chris Burghart's
experiences with the Samsung). That is, inside of an X11 session with
Netscape running, you can hit the suspend button and go away for a while,
then come back, hit the suspend button again, and have your network
connection still up and running.
<h4>IrDA</h4>
The IrDA port's use under Linux is currently a mystery. It appears
to need some sort of enabling, that is, it is not automatically
active. Some other laptops apparently have a choice in the BIOS
setup for this; unfortunately, I haven't found anything concerning
the IrDA port in the Compaq diagnostics, say.
