the standby switch which worked under Linux
without problems.

Installation of SuSE Linux 7.0 Professional went
smoothly – YaST2 configured the XF86 _SVGA-
Server and then included the integrated Ether
Express Pro 100 from Intel. But the installation of
the sound card, an ESS 1978 Maestro 2E, was
something the SuSE-Tool found too hard a nut to
crack – the kernel module refused to co-operate.
But with modprobe maestro the sound card was
installed by hand with no further problems.
During the entire installation the display
flickered noticeably. After changing to text mode it
was hard to recognise anything at all, in fact. This
probably stems from the mode lines in YaST2 not
being quite correct. After a reboot, though, the
phenomenon disappeared and was never
encountered again.
The Irda chip was not recognised by findchip
using irda-utils but could be used as /dev/ttyS1.
What matters more is that in the kernel under
Character devices the option
CONFIG_SERIAL_DETECT has been selected and in
the start script of the irmanager the second serial
port is assigned to IRQ 3 via setserial.
CardBus problems
A further surprise was waiting for us. In the manual
Compaq states with regard to PCMCIA and CardBus
that, at least under Windows 2000, one can only
exchange cards with the device switched off. Funnily
enough, this also seemed to relate to Linux because
after every insertion or removal of a card (with
cardmgr running), the kernel promptly died.
The solution is to manually enter the irq-lines of
the card services – we used IRQs 7, 9, 10 and 15 for
PCMCIA and IRQ 11 for CardBus. After these
entries the cards could be changed at will.
The CardBus controller from Texas Instruments
PCI 1450 needed for the initialisation of our Type-III-
PCMCIA hard disk a good 20 seconds to get going.
During this period the whole system was paralysed.
The positioning of the two Type-II CardBus slots at
front right of the device may be something of a
nuisance with some cards that have lots of external
cable connectors, but on the other hand they
remain astonishingly cool at just 30 degrees. The
overheating which occurs with other notebooks will
not happen to this one.
The only thing we found irksome was the
dummy inserts used to cover the CardBus slots – in
practice they’re bound to get lost or damaged.
Spring shutters which close automatically after the
cards are removed are better. Compaq also supplies
as an accessory a shutter for the drive slot so that
for example on an aeroplane where built-in CD-
ROM- and DVD-drives are not allowed you don’t
have to sit around with a hole in the side of your
notebook.
Big Brother X11
Last of all we have a piece for the Cabinet of
Curiosity. As already known from the world of
desktop PCs, it’s frequently the case that when
restarting the X-server, you can see the old screen
content for a fraction of a second. The reason is that
the graphics RAM is not completely flushed at every
X start or X shutdown and is only wiped when
power is lost. However, this isn’t the case with the
Compaq Armada – hours later the desktop from the
last session is clearly visible for just under half a
second.
This is perhaps not enough to spy out complex
management structures, but may convict the son of
his “immoral” internet activities on daddy’s laptop.
So it is worthwhile restarting the X-server again
before shutting down the computer or at least to
close any traitorous windows.
Conclusion
The Compaq Armada M700/7700 is one of the
best notebooks in our test. All the integrated
hardware could be installed with minor tweaks to
the standard installation. The only niggle was
that the sleep mode under X11 always ended
with a crash, while no report of this problem was
seen on the console. It was also a bit difficult to
keep the Armada on one’s lap. The main air vent
lies over the left knee and warms it to just under
60 degrees. – it might help cure rheumatism but
isn’t ideal for constant use. As you’d expect, the
only thing left to say is that it’s a pitty that
Compaq does not offer this device pre-installed
with Linux. ■
