The M5N (aka M5200N) is a 3.4lb, 1"-thick Centrino subnotebook from Asus. The S5N (aka S5200N) is a one-spindle version of the M5N, weighing 3lb, with an external USB DVD/CDRW as a bundled accessory. Asus sells the S5Ne as a single-configuration, 1 GHz, all-white version of the S5N. The M5N and S5N are sold through resellers, sometimes with other names (e.g., the Chembook 2250 and Chembook 2150). The information here should apply to rebranded M5N and S5N laptops also.
This page is about how to install Debian GNU/Linux on your M5N, S5N, or similar laptop. If you're looking for a review, here is my mostly positive opinion of my M5N.
Update: the M5N is now available with a Dothan CPU, and may also ship with an Intel 2200 802.11g wireless chipset. I don't have a new M5N to play with, so I'm including three third-party reports, below.
Update, Jan 2006: fan control and suspend-to-RAM are finally working! Many thanks to Bill Farrow, who told me how. Details below.

I also have a VESA VGA framebuffer working so that I can run Bootsplash. Silent mode (i.e., a progress bar instead of boot and shutdown messages) doesn't really work under Debian yet. But verbose mode works fine.

This was an IRQ sharing problem. Make sure you enable "Local APIC support on uniprocessors" and "IO-APIC support on uniprocessors" in your kernel config.

unzip firmware-version.zip mv ipw2100-1.1.fw /usr/lib/hotplug/firmware module-assistant a-i ipw2100 modprobe ipw2100You might want to set ipw2100.ko to load automatically as eth1. Just add an alias to any file in /etc/modprobe.d:
alias eth1 ipw2100Remember to run update-modules. Then add eth1 to your /etc/network/interfaces file:
auto lo eth0 eth1 ... iface eth1 inet dhcp pre-up /sbin/iwconfig eth1 essid <name-of-network>If you use several different networks and your wireless card supports ESSID scanning (the Intel PRO 2100B does), you can use my essid-pick script to choose from a prioritized list.
iface eth1 inet dhcp pre-up /usr/sbin/essid-pick eth1 <network1> <network2> ...

Starting with 2.6.20, fan control should work again. Those of you with kernels between 2.6.17 and 2.6.19 should probably just upgrade.

Sebastian Henschel from Xtops.DE wrote in with this report:
you could make an addendum for the latest M5200N (sold in germany, at least), ASUS now ships that model in a Dothan-based setup:
- you need an updated speedstep-centrino driver (should be in 2.6.8).
- the wireless was unfortunately replaced by the ipw2200 (802.11g) chip which does not work with ndiswrapper 0.9 or driverloader 2.02. i did not even dare to try the free driver from Intel which failed for me last week when working on a Toshiba Tecra S1 (as the others failed, too).
- did not notice any changes when looking at chipset and graphics.
Cezary Czaplewski got the Intel 2200B wireless chipset and Dothan SpeedStep in the updated M5N to work:
I have a new M5N with ipw2200 (802.11g) wireless and it does work with both ndiswrapper 0.9 and linuxant driverloader 1.73.
On Fedora 2 I had to increase the kernel stack size to 16k, CONFIG_4KSTACKS (which is the default in Fedora Core 2) gives kernel with only 4k stack and it is not enough for Intel Centrino PRO/Wireless 2200BG windows driver. I am using 16K kernel sources from http://www.linuxant.com/driverloader/wlan/full/downloads-fc2-kernel-i686.php
I have not tried 8K stack kernel yet.
I have updated speedstep-centrino driver for Dothan 1.7 Ghz myself (diff attached), as even kernel 220.127.116.11 has no support for Dothan's speedstep.
Nicola Di Nisio reports that the new M5N works well with SuSE 9.2 but not SuSE 9.1. The ipw2200 (802.11b/g wireless), suspend-to-disk, the touchpad, and ACPI all work fine. The SD-card slot and suspend-to-RAM still do not work.
