simple, on normal systems where one can compile their own kernel, this is easy. Just compile ibm_acpi as a module. Then  <pre>echo ibm_acpi experimental=1 >> /etc/modules</pre>
 
  
−
after the system boots, there will be extra stuff in /proc/acpi/ibm. We are mainly looking at the ecdump file located in that directory tree. this file is somewhat of a live hex matrix that allows you to control some things that bios usually has control over. So many thanks to the uberness off some backwards kids we have the hex number 0x2f which is the offset for the fan controls. so when one types:
 
−
<pre>echo 0x2f 0x07 > /proc/acpi/ibm/ecdump</pre>
 
−
we are telling the fan (offset 0x2f) to operate at it's maximum capabilities. (0x07 is for max speed)..
 
  
−
though i have only read about this. One could pass the <pre>experimental=1</pre> argument on the boot line for the kernel, if the module is--and which happens to be--built-in. though i don't have the syntax for such thing in my head right now... tsk tsk tsk.

Issue
Wireless device recognized, not working
Details
First thought was that the integrated Bluetooth device was having some kind of hardware conflict with the wireless card. Running rfkill list showed the wireless card subject to a hardware block, which usually stems from a wireless switch. However, flipping the wireless switch (physical switch immediately below the center of the palm rest, SoftKey = Fn+F2) would bring the bluetooth up and then down, but leave the wireless as it was. Turns out, the solution was a BIOS option.
Solution
  • Enter BIOS (F1 on POST)
  • Go to Config -> Network
  • Set the Wireless LAN Radio Frequency option to On

And you're golden. Sheesh.

Thinkpad R61

Issue
Systems with BIOS passwords do not netboot correctly: System reboots when an option is selected
Solution
Install a hard drive, network boot should behave normally. Working hypothesis is the locked BIOS passes incorrect system information about a drive being present, and clobbers the netboot.
Working hypothesis is wrong, after cracking the BIOS password and updating to BIOS version 2.29, the problem is the same until a HDD is installed. Lynnae 22:58, 6 September 2012 (UTC)
