Introduction


The Acer Aspire 1511 LMI is an AMD64 based laptop. I obtained mine in june 2004. The machine is based around the following CPU:

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 4
model name      : AMD Athlon(tm) 64 Processor 3000+

cpu MHz         : 1800.000

hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow up ts fid vid ttp
bogomips        : 3594.80


I've used this machine both running a 64 bit gentoo and 32 bit Debian and now 32 bit Ubuntu. The main reason why I don't use any 64bit OS on it is because of the lack of proper wireless support. The cpu also has 64k l1 chace and using powernow it support 3 throttling modes:

A main problem I had when using Debian earlier was that I was unable to query the battery status which was due to a faulty DSDT (documented here for example). I have no clue wheter this is an Ubuntu fix or something generic but querying the batter information isn't that grand now but at least you're getting some estimate now. Suspend to ram and hibernate are fully functional now, although I can't recall if suspend to RAM worked previous also.
The gigabit ethernet onboard is simply a tg3 and as rather default that simply works.

Hard disk throughput:

edb@elske:~$ sudo hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   1476 MB in  2.00 seconds = 737.19 MB/sec
 Timing buffered disk reads:   80 MB in  3.02 seconds =  26.51 MB/sec

The installation


Well I simply wrote the CD, performed that install and a basic system was up and running. The only thing giving me troubles was the wlan which is described below. After the installation I used EasyUbuntu to get flash, java, nvidia etc installed. 3D acceleration is only a matter of getting running nvidia-xconfig.

Wireless


The major pain in the ass on this laptop is getting the wireless to work. After a defult Edgy install is kinda 'sees' the wireless interface but everything related to getting it work fails. This is mainly traced back to

[17179590.412000] bcm43xx: Error: Microcode "bcm43xx_microcode5.fw" not available or load failed.


Some tutorials on the Internet suggest using some fwcutter tool to obtain this microcode, but the same tutorials say this will result in a degraded performance. So I decided to follow the ndiswrapper way. So I simply installed the following packages:

edb@elske:~$ dpkg -l | grep ndis
ii  ndiswrapper-common                         1.18-1ubuntu2                 Userspace utilities for ndiswrapper
ii  ndiswrapper-utils-1.8                      1.18-1ubuntu2                 Userspace utilities for ndiswrapper


After this ndiswrapper still requires the original windows drivers. I downloaded this from: ACER, more specifically this file. (Mental note, mirror this file). Once extraced you'll see:

edb@elske:/tmp$ find 80211G/
80211G/
80211G/0x0409.ini
80211G/80211g.zip
80211G/AUTORUN.INF
80211G/Data1.cab
80211G/Driver
80211G/Driver/bcm43xx.cat
80211G/Driver/bcm43xxa.cat
80211G/Driver/bcmwl5.inf
80211G/Driver/bcmwl5.sys
80211G/Driver/bcmwl5a.inf
80211G/instmsia.exe
80211G/instmsiw.exe
80211G/isscript.msi
80211G/setup.exe
80211G/Setup.ini
80211G/WLAN.ico
80211G/WLAN.msi


A quick overview of the ndis flags:

edb@elske:/tmp$ ndiswrapper 
Usage: ndiswrapper OPTION

Manage ndis drivers for ndiswrapper.
-i inffile        Install driver described by 'inffile'
-d devid driver   Use installed 'driver' for 'devid'
-e driver         Remove 'driver'
-l                List installed drivers
-m                Write configuration for modprobe
-da               Write module alias configuration for all devices
-di               Write module install configuration for all devices
-v                Report version information


where 'devid' is either PCIID or USBID of the form XXXX:XXXX


Looks simple doesn't it ? Well I simply went to the driver subdirectory and installed both .inf files:
edb@elske:/tmp$ cd 80211G/Driver/
edb@elske:/tmp/80211G/Driver$ sudo ndiswrapper bcmwl5.inf 
edb@elske:/tmp/80211G/Driver$ sudo ndiswrapper bcmwla5.inf 
edb@elske:/tmp/80211G/Driver$ ndiswrapper -l
Installed drivers:
bcmwl5          driver installed, hardware present 
bcmwl5a         driver installed, hardware present 


So far so good. After this I blacklisted the old driver and threw it out:

echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
sudo rmmod bcm43xx


And used the other flags of ndiswrapper in order to get the modprobe files writen:

sudo ndiswrapper -m
sudo ndiswrapper -da
sudo ndiswrapper -di


After this the nidswrapper module needs to be loaded manually:

modprobe nidswarpper


Which results in the following output in dmesg:

[17182648.428000] ndiswrapper version 1.22 loaded (preempt=no,smp=yes)
