+====== Short Survey on the Lifebook S-5582 ======
+Which Hardware does work with Linux and which does not. All setup was done on a [[Debian]] system linux running a 2.4 series Kernel. I recently switched to a 2.6 series Kernel all 2.6 configuration info will be put on it's own page: [[lifebook-2.6]].
+===== Sound =====
+The onboard sound device is identified as followed in /proc/pci:
+  Bus  0, device   0, function  1:
+     Multimedia audio controller: Intel Corp. 82440MX AC'97 Audio Controller (rev 0).
+       IRQ 9.
+       I/O at 0x1000 [0x10ff].
+       I/O at 0x1400 [0x143f].
+The 2.4 series kernel comes with "Intel ICH (i8xx) audio support" (i810_audio.o) but this driver does only support 44kHz files and I wasn't able to use it with sox's play or with mpg123. The better choice is the alsa driver.
+Enable the sound support in the kernelconfig and get the alsa-driver package from http://www.alsa-project.org - Unpack it and run
+  ./configure
+  ./snddevices
+  make
+  make install
+Then add the following three modules to your /etc/modules
+  snd-intel8x0
+  snd-pcm-oss
+  snd-mixer-oss
+The alsa modules do set all mixer settings to zero so it makes sense to set them to a useful state on bootup. Just install setmixer:
+  apt-get install setmixer
+Note the Laptop disables the internal speakers when a headphone is plugged in - I like that.
+===== Video =====
+The Lifebook comes with an ATI Rage Mobility with 8 MB RAM:
+   Bus  0, device  20, function  0:
+     VGA compatible controller: ATI Technologies Inc Rage Mobility P/M (rev 100).
+       IRQ 9.
+       Master Capable.  Latency=66.  Min Gnt=8.
+       Non-prefetchable 32 bit memory at 0xfd000000 [0xfdffffff].
+       I/O at 0x2000 [0x20ff].
+       Non-prefetchable 32 bit memory at 0xfc005000 [0xfc005fff].
+This chipset is supported in the actual XFree86 package by the ''ati'' server.
+<file>
+Section "Device"
+        Identifier      "ATI Rage Mobility"
+        Driver          "ati"
+EndSection
+</file>
+I wasn't able to enable any accelerated framebuffer (atyfb or aty128fb) but I get no errormessages so maybe I did something wrong - Any help is appreciated.
+However the VESA framebuffer works fine. Only fbi (a tool to view images on the framebuffer device) freaked me out. On displaying a jpeg file it faded the screen to white and freezed everything - I had to do an hardreset.
+===== Network =====
+The onboardchip identifies itself as:
+   Bus  0, device  18, function  0:
+     Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139 (rev 16).
+       IRQ 9.
+       Master Capable.  Latency=64.  Min Gnt=32.Max Lat=64.
+       I/O at 0x8000 [0x80ff].
+       Non-prefetchable 32 bit memory at 0xfc004800 [0xfc0048ff].
+It is suppored by the "RealTek RTL-8139 PCI Fast Ethernet Adapter" kernel driver (8139too.o).
+The driver supports the "Media Independent Interface" (MMI) mode. So it's able
+to detect plugging in an ethernet cable by using ifplugd.
+  #> apt-get install ifplugd
+Edit ''/etc/default/ifplugd'' like this:
+<file>
+INTERFACES="eth0"
+HOTPLUG_INTERFACES=""
+ARGS="-q -d5 -w -I"
+SUSPEND_ACTION="stop"
+</file>
+It will execute ''ifup'' or ''ifdown'' when a cable is plugged in or out.
+Lately the machine behaves strangely. It only initializes the network card when
+connected to AC or when the battery is 100% full. This is the same for Linux and
+Windows. There is no way to access the card then - even lspci is unable to find
+it. If anyone knows how to fix this please contact me or write it here!
+===== USB =====
+   Bus  0, device   7, function  2:
+     USB Controller: Intel Corp. 82440MX USB Universal Host Controller (rev 0).
+       IRQ 15.
+       Master Capable.  Latency=64.
+       I/O at 0x1460 [0x147f].
+The USB controller works fine with the standard UHCI kernel driver (usb-uhci.o). Be sure to install the usb-manager:
+  #> apt-get install usbmgr
+===== Firewire =====
+   Bus  0, device  17, function  0:
+     FireWire (IEEE 1394): PCI device 104c:8026 (Texas Instruments) (rev 0).
+       IRQ 9.
+       Master Capable.  Latency=64.  Min Gnt=2.Max Lat=4.
+       Non-prefetchable 32 bit memory at 0xfc004000 [0xfc0047ff].
+       Non-prefetchable 32 bit memory at 0xfc000000 [0xfc003fff].
+I don't own a firewire device so I could not test it, but the "OHCI-1394" kernel
+driver (ohci1394.o) loads without errors so I suppose it's working. However it
+prevents the machine from going to Suspend-to-RAM mode so leave it out if you
+don't need it.
+===== PCMCIA =====
+/proc/pci says:
+  Bus  0, device  19, function  0:
+    CardBus bridge: O2 Micro, Inc. OZ6933 Cardbus Controller (rev 2).
+      IRQ 9.
+      Master Capable.  Latency=168.  Min Gnt=128.Max Lat=4.
+      Non-prefetchable 32 bit memory at 0x10000000 [0x10000fff].
+  Bus  0, device  19, function  1:
+    CardBus bridge: O2 Micro, Inc. OZ6933 Cardbus Controller (#2) (rev 2).
+      IRQ 9.
+      Master Capable.  Latency=168.  Min Gnt=128.Max Lat=4.
+      Non-prefetchable 32 bit memory at 0x10001000 [0x10001fff].
+The PCMCIA driver works fine with the stock Kernel ''Yenta compatible CardBus''
+driver. Just install the PCMCIA utils:
+  #> apt-get install pcmcia-cs
+===== Modem =====
+Bad news. /proc/pci says:
+   Bus  0, device   0, function  2:
+     Modem: PCI device 8086:7196 (Intel Corp.) (rev 0).
+       IRQ 9.
+       I/O at 0x1800 [0x18ff].
+       I/O at 0x1480 [0x14ff].
+Windows installs it as "Lucent Softmodem AMR" which is not supported on linux (see http://www.linmodems.org ). I knew it when I bought the laptop but as I don't need the modem it didn't matter to me.
+The ''scanmodem'' tool available at http://linmodems.technion.ac.il/ prints this information:
+<code>
+Providing detail for device at PCI_bus 0000:00:00.2
+  with vendor-ID:device-ID
+            ----:----

+        AgereSystems
+        Smartlink
+</code>
+===== Harddisk =====
+My model comes with a 20 GB harddisk (''FUJITSU MHN2200AT'') here are some specs:
+<code>
+#> fdisk -l /dev/hda
+Disk /dev/hda: 20.0 GB, 20003880960 bytes
+heads, 63 sectors/track, 2432 cylinders
+Units = cylinders of 16065 * 512 = 8225280 bytes
+   Device Boot      Start         End      Blocks   Id  System
+/dev/hda1   *           1        1156     9285538+   c  W95 FAT32 (LBA)

+/dev/hda3            2373        2432      481950   82  Linux swap
+</code>
+I added the following kernel params to my /boot/grub/menu.lst (for lilo use the append command) but with no remarkable speedincreases:
+  ide0=autotune hda=autotune
+===== DVD/CD-RW =====
+My Lifebook comes with a DVD/CD-RW combo drive.
+  /proc/ide/hdb/model
+     TOSHIBA DVD-ROM SD-R2102
+For burning CDs you must enable "generic SCSI support" and "SCSI emulation support" then pass the following command to the kernel on boot (via lilo or grub):
+  hdb=scsi
+This makes the CD-Rom drive available as ''/dev/scd0'' (adjust your
+''/etc/fstab'' to reflect this)
+Output of 'cdrecord -scanbus':

+</file>
+===== IRDA =====
+It does work with the smc-ircc driver. Simply put the following line into /etc/modutils/irda :
+<file>
+  alias irda0 smc-ircc
+</file>
+install the IRDA tools
+  #> apt-get install irda-tools
+and edit ''/etc/irda.conf'':
+<file>
+IRDADEV=smc-ircc
+DONGLE=none
+DISCOVERY=-s
+ENABLE=no
+</file>
+===== Mouse =====
+The buildin touchpad works fine as ps2 mouse.
+gpm.conf
+<file>
+device=/dev/psaux
+responsiveness=
+repeat_type=raw
+type=ps2
+append=""
+sample_rate=150
+</file>
+In XF86Config use this:
+<file>
+Section "InputDevice"
+        Identifier      "Configured Mouse"
+        Driver          "mouse"
+        Option          "CorePointer"
+        Option          "Device"                "/dev/gpmdata"
+        Option          "Protocol"              "GlidePointPS/2"
+        Option          "Emulate3Buttons"       "true"
+EndSection
+</file>
+===== Powermanagement =====
+The Lifebook comes with a Pentium III mobile processor. I didn't try any
+speedstep patches for the 2.4 Kernel instead I enabled autoswitching in the
+BIOS. This decreases the CPU speed on boot when running on battery power.
+Advanced Powermanagement (APM) including Suspend-to-RAM works fine. Just enable
+APM support in the Kernel and install the APM daemon.
+  #> apt-get install apmd
+===== Multimedia Buttons =====
+Like the scrollbuttons the multimedia buttons above the keyboard do not create
+any scancodes with ''showkey'' so they are not usable out of the box. I didn't
+look for a solution because I don't really need them.
+===== Conclusion =====
+The lifebook is a small, lightweight, silent but powerful machine with hardware that ist mostly covered by the current linux drivers. It's a good replacement for my old Omnibook800. I love it!
