PC: Overview of the Linux related features of the Compaq Armada M700

Table of contents

1. Preface

This is a quick survey about Linux related hardware features of the Compaq Armada M700. I don't try to explain the usual installation details (for instance, which partitions I have made, what they are good for and so on and so on...). Requests for additional information may be directed by eMail to the author.

The laptop doesn't come bundled with ugly stuff like the infamous hidden "BIOS" partition, which was real common on Compaq desktop machines. A nice goodie is the facility to boot the notebook over a LAN (not needed here yet, but a nice to have feature).

The machine comes with APM v1.2. Standby- or suspend-mode is established by software (stock Linux apm utilities) or pressing the appropriate hardware button. The laptop, especially the keyboard, needs some time to wake up again, but APM works after all.

2. Installation

My Compaq Armada M700 runs these days on Gentoo Linux. Before there was Debian GNU/Linux 3.0 installed (vamped up with some backports). Both distribution avoid auto-configuration and some other here not wanted mumbo jumbo.

The system performs also well with:

but that's another story.

3. General Hardware Data

3.1 General system information:

3.2 RAM

I bought the machine with 192 MB SDRAM (PC 100). 64 MB of them are fix installed on the system board, one of the two expansion banks houses a stick with 128 MB. I installed another stick with 64 MB in the second expansion bank, which brings the system's total memory up to 256 MB.

The laptop is quite happy with stock PC-100 SDRAM, no need to buy OEM sticks.

3.3 Hard disk

3.4 CD-ROM

Compaq "CD-224E" (24X Atapi) in the multi-bay.

3.5 Floppy drive

I'm a lucky owner of a floppy drive for this machine. The floppy drive is designed as a plugin for the multi-bay, but my multi-bay is used for housing my CD-ROM. But there is a parallel port cable as acessoire for the drive available, and this combo is even hot pluggable.

The sytem is bootable in both variations.

3.6 Graphic chip

ATI Rage Mobility P/M AGP with 8 MB RAM

This chip displays a resolution from "1024x768" with the Xserver "ati" from XFree86 4.1. Some hints form my XF86Config:

   Section "Device"
         Identifier      "ATI Rage Mobility"
         BoardName       "Rage Mobility Pro"
         VendorName      "ATI"
         Driver          "ati"
         ChipSet         "mach64"
         BusID           "PCI:01:00:0"
         VideoRam        8192

   Section "Monitor"
         Identifier      "TFT"
         HorizSync       28.0-96.0
         VertRefresh     50.0-62.0
         Option          "DPMS"

This chip doesn't handle DRM/DRI or X video extensions out of the box, but the GATOS project offers extension drivers for X video. They are available as source tarballs or as binaries, both for different XFree86 versions and perform quite well with MPlayer. As I don't need hardware acceleration on my laptop, I use the native drivers shipped with XFree86 vamped up with the GATOS extensions.

The chip performes well with the kernel's VESA driver on console and displays a resolution from "1024x768" - or 128 columns and 48 lines - with 16 bit color on text consoles. It's no problem to switch from the VESA console to the ATI X server and back. To enable the VESA mode for console, you need some options in your kernel configuration:


To make it all come true, the kernel needs to be booted with the append switch "vga=0x317".


Card bus bridge: Texas Instruments PCI1450

You need the modules pcmcia_core and yenta_socket. I have sometimes a Cisco Aironet 350 WLAN card inserted, which works fine on this card bus.

3.8 Sound

ESS Technology ES1978 Maestro 2E

The sound comes quite clear, but with all common disadvantages of sound on laptops (very weak basses and so on ...).

3.8.1 OSS

The module maestro loads with the two lines in /etc/modprobe.conf:

   alias char-major-14 maestro
   options maestro dsps_order=2 use_pm=1

3.8.2 ALSA

The module snd_es1968 needs the following lines in /etc/modprobe.conf:

   alias char-major-116 snd
   alias char-major-14 soundcore

   alias snd-card-0 snd-es1968
   alias sound-slot-0 snd-card-0

   alias sound-service-0-0 snd-mixer-oss
   alias sound-service-0-1 snd-seq-oss
   alias sound-service-0-3 snd-pcm-oss
   alias sound-service-0-8 snd-seq-oss
   alias sound-service-0-12 snd-pcm-oss

   alias /dev/mixer snd-mixer-oss
   alias /dev/dsp snd-pcm-oss
   alias /dev/midi snd-seq-oss

   options snd cards_limit=1

3.9 Trackpoint

The notebook's got a trackpoint like the IBM Thinkpads and three "mouse" buttons. The whole stuff is recognized as a PS/2 mouse and works in X and on console with gpm started like this:

   # /usr/sbin/gpm -m /dev/psaux -t ps2 -Rraw -3

The X mouse listens to /dev/gpmdata. Here are some lines from my XF86Config:

   Section "InputDevice"
         Identifier      "Trackpoint"
         Driver          "mouse"
         Option          "CorePointer"
         Option          "Device"                "/dev/gpmdata"
         Option          "Protocol"              "PS/2"

3.10 Keyboard

The keyboard comes quite unspectular as a generic model with 104 keys. For getting the laptop (Fn) keys to work you'll need a BIOS build later than 23-May-2000. Older BIOSes seem to depend on Windows specific software.

I updated to the latest available BIOS (686H_20020315A, 15-Mar-2002), which also enables switching in the BIOS to different TV output formats.

This description of the Fn-keys and their usage is "borrowed" from Frank Steiner's Site, which describes a Linux-Powered Compaq Armada E500:

Fn-Key combo Purpose
Fn-Suspend button The suspend button is the blue round button. When pressed alone, the laptop suspens to RAM, if pressed together with Fn, it saves to disk (if this is enabled under Windows or with a Kernel >= 2.5).
Fn-T Toggle stretching resolutions lower than 1024x768.
Fn-F4 Switch between TFT screen and external monitor. Both screens can be run in parallel without problems. The external screen can be connected at any time.
Fn-F5 Activates the sound setting mode. With the left/right cursor keys you can lower/increase the volume of the speaker. The down cursor key will play a beep so that you can check the volume. Leave the mode with Fn-F5 again.
Fn-F6 Activates the quicklock.
Fn-F7 It activates the power saving mode. You can flip through the power saving schemes with the cursor keys.
Fn-F10 Activates the brightness mode. You can now lower/increase the screen brightness with the left/right cursor keys.

3.11 Infrared port - IrDA(TM)


The output of "setserial -g /dev/ttyS2", after

   /dev/ttyS2: Device or resource busy

There are no units with infrared ports all around here, so I haven't tested it yet. On the other hand there are no error messages on loading the modules or attching the device to the IrDA services in the syslog, so that everything seems to work.

On christmas holiday there was a friend of mine with a mobile phone around - and: It works, Yeehaw!

3.12 USB

USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB

As long as the machine got no floppy drive, I used an USB memory stick as my only writable removable storage medium. The USB controller needs the kernel modules usbcore and uhci, kernel's storage subsystem usb-storage and SCSI hard disk support.

In user space I prefer hotplug over usbmgr.

The output of /proc/bus/usb/devices:

   T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
   B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0

   E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=255ms

3.13 Ethernet chip

Ethernet controller: Intel Ethernet Pro 100

The on board chip uses the kernel module eepro100 and works like a charm.

3.14 Lucent LT WinModem

Serial controller: Lucent Microelectronics LT WinModem

The modem is on a mini PCI card and is a WinModem (aargh!). But anyway: A properly working driver is available at the LinModem Website.

The driver is composed of two kernel modules, which are compiled from very comfortable scripts included in the source tarball. There are also scripts for building RPM or Debian packages if required. Just install the driver package and kernel sources or kernel headers and see ...

There is no need to load the two kernel modules lt_serial and lt_modem before establishing the PPP connection, if you use the Debian package, which copies the modules to the correct places, sets symbolic links, drops a few lines in the modules configuration mechanism and so on. Just use wvdial or your dialup scripts - and they will be there.

The modem connects after all that fiddling as smooth as an on a former machine of mine used PC card modem.

Here is the download site for drivers to build with 2.6 Kernels.

5. Survey PnP Devices

There are no PnP devices on board. The kernel output:

   isapnp: Scanning for PnP cards...
   isapnp: No Plug & Play device found

6. Survey RS232

Output from "setserial -ga /dev/ttyS[0-3]":

   /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
         Baud_base: 115200, close_delay: 50, divisor: 0
         closing_wait: 3000
         Flags: spd_normal skip_test

   /dev/ttyS1, Line 1, UART: unknown, Port: 0x02f8, IRQ: 3
         Baud_base: 115200, close_delay: 50, divisor: 0
         closing_wait: 3000
         Flags: spd_normal skip_test

   /dev/ttyS2, Line 2, UART: 16550A, Port: 0x03e8, IRQ: 3
         Baud_base: 115200, close_delay: 50, divisor: 0
         closing_wait: 3000
         Flags: spd_normal skip_test

   /dev/ttyS3, Line 3, UART: unknown, Port: 0x02e8, IRQ: 3
         Baud_base: 115200, close_delay: 50, divisor: 0
         closing_wait: 3000
         Flags: spd_normal

/dev/ttyS0 is the serial port (COM1), /dev/ttyS2 is the infrared port.

7. Conclusion

All hardware works well with a recent Linux kernel and my favourite distribution. There are no show-stoppers all around.
