Finally after awaiting for about less than 2 months, I got my T61 from Lenovo yesterday. Well, my first impression is worth wait. Here is my T61 configuration:

What did I do the first minute

Powered on T61 and hold the ThinkVantage button to go BIOS. Well, this is my first T61. I did notice the options to enable/disable the Virtualization Technology which I was most concerned about. I shall brief things soon here for people who are looking to install Linux and probably detail later.

Fedora 7 Installation

- Booted up from DVD - Fedora 7 Installation takes a long time to load AHCI driver, however, it does not recognize the disk. I put in FC7 LIve disk which fails to mount root because it couldn't locate the disk. To work around this problem, I had to switch SATA mode from AHCI to Compability mode in BIOS. Installation then went smooth and finished in less thatn 10 min.

Fedora 7 Xenified Kernel

yum groupinstall "Virtualization"

Xen kernel booted fine without any problems.

NVidia Quadro 140M - Non Xen Kernel

I was able to compile nvidia.ko module from for non-xen 2.6.21-1.3194.fc7-i586 kernel. Downloaded the latest from and simply ran the program and it took care rest of it. The xorg.conf file worked for the first time without any problems.

However, for the xen kernel, its a whole different story.

NVidia Quadro 140M - Xenified Kernel

As expected, nvidia.ko module failed to load into 2.6.20-2925.9.fc7xen-i686. The new nvidia pkg doesn't even try to compile the module for xen kernel, they look the xen kernel and quit the program. However, if you unpack the pkg and look in the NVIDIA-Linux-x86-100.14.11-pkg1/usr/src/nv/ there is a variable the script looks if it wants to ignore the xen kernel, so I tried follow steps.

export IGNORE_XEN_PRESENCE=true   // This basically let me atleast try compiling the module. Then followed the usual nvidia patch procedure but in vain. However I am pasting steps to debug further.

yum install kernel-xen-devel.i686;
cd /usr/src/kernels/2.6.20-2925.9.fc7xen-i686/;
make oldconfig;
make scripts;
make prepare;
mkdir nv_xen;
cd nv_xen;
mv attachment.php\?attachmentid\=20801 xen.patch;
sh ./ --extract-only;
cd NVIDIA*/usr/src/nv;
patch -p1 < ../../../../xen.patch;
CC="gcc -DNV_VMAP_4_PRESENT -DNV_SIGNAL_STRUCT_RLIM" make SYSSRC=/lib/modules/2.6.20-2925.9.fc7xen/source/ module;
cp nvidia.ko /lib/modules/2.6.20-2925.9.fc7xen/kernel/drivers/video/;
depmod -a;

I tried inserting the built module but it couldn't find some symbols and I couldn't get it to work. Well, I forgot compiz for a while and wanted to just get the Xen HVM taste. So tried to use the xorg's nv driver and interesting, that failed too.

I had to crack my head to get this X in xen kernel. So made up my mind and wanted to give the generic VESA driver a shot and it worked!!! Finally some XServer with XEN.

yum remove xorg-x11-drv* // remove all nv drv and all xorg stuff

yum install system-config-display  // yum selects minimum dependencies for this, includes xorg-server and xorg vesa driver
sudo system-config-display

Select generic LCD 1440x900 and it worked fine. So my X on Xen is running off of vesa driver.


I will trying this tonight and will update the wiki. Here is my xm info.

Update: Was easier than I thought ;-) . Using the fully virtualized config to run windows. Used the Virtual Machine Manager came with fedora and was just an easy setup. Works awesome!!

Wireless - Intel 4965

This was a tough one but finally there was one bug posted on T61 issue which helped me to get this working. Here are steps in brief.

- Got the rpm for Intel 4965 firmware. Install this will copy firmware files to /usr/lib/firmware

rpm -ivh iwlwifi-4965-ucode-4.44.15-4.noarch.rpm

- Make sure mac80211 is loaded.

modprobe mac80211

- Get the iwlwifi package from intel to compile the iwl4965 package


- Dont be exited to compile that yet because it wont work on T61 because of PCI ID bug on T61. See this link So get the patch.


- Extract the iwlwifi folder and apply the above patch using patch -pl or simple edit them manually, they are just couple changes in adding the PCI ID to the code.

- After apply the patch if you try to run make, it will still fail because I guess simple relative path problem. It gave me error looking for files in ../net/mac80211 which actual path is /usr/src/kernels/2.6.21-1.3194.fc7-i686/net/mac80211, so I created a link in the unzipped iwlwifi folder like below and then ran make.

ln -s /usr/src/kernels/2.6.21-1.3194.fc7-i686/net .

This time make was successful and it compiled the module in compatible/iwl4965.ko .

- Insert the module

insmod compatible/iwl4965.ko

- Activate the wireless device

ifconfig wlan0 up

- Test Use iwconfig to test and configure. Enjoy!!!
