Installing LFS on a ThinkPad T41p

---

Graphics

internal, AGP: ATI Radeon FireGL T2

coming soon...

PCI of dock: ATI Radeon 9000

You will have to enable ati drivers when you compile X. DRI support is present starting from XFree86 4.3.0. However, it segfaulted on my machine until i updated to 4.3.99.902, so 4.4.0 should work. OpenGL apps were still very slow until i set the R200_NO_TCL environment variable. It disables hardware TCL support, so i guess the driver is still buggy in this field. Now i'm getting framerates a bit below 600 fps with glxgears, which i think is quite ok for a PCI based card in a dock.

Drives

Harddisk: Hitachi Travelstar HTS548080M9AT00

I replaced the original harddrive (60GB at 7260RPM) with the 80GB/5480RPM model from Hitachi (which are the ones that IBM labels for their purposes). For some speed optimizations you might try the following (at your own risk):

hdparm -c 3 -u 1 -X 99 -k 1 /dev/hda

DVD/CDRW Combo: Toshiba SD-R9012

coming soon...

Ultrabay 2000 ZIP Drive (in docks Ultrabay 2000)

coming soon...

Sound: ...

coming soon...

Networking

LAN: Intel Pro/1000 (82540EP)

Compile the e1000 driver into the kernel or as module (CONFIG_E1000). You might want to take a look at ifplugd.

Wireless LAN: Atheros AR5212 802.11abg (aka IBM a/b/g)

The madwifi project will be your friend. You might want to give waproamd a try.

Modem

coming soon...

PCMCIA

Just enable the PCMCIA support in the kernel configuration and with it the cardbus driver and the thing will work great. I tested a Xircom CardCaddy as well as some other CompactFlash adapter. Both worked.

USB

coming soon...

Specials

UltraBay

coming soon...

Thinklight

Works by pressing [FN-PAGEUP], since it's controlled by the BIOS.
However, if you want to get advanced control over it, ibm-acpi will enable you to do a

echo on >/proc/acpi/ibm/light    ...to turn it on

or

echo off >/proc/acpi/ibm/light    ...to turn it off.

special keys

By using ibm-acpi, tpb and xmodmap you can make use of all the specific special keys.
Have a look here on how to configure them.

Trackpoint

coming soon...

Touchpad

coming soon...

Docking Station (IBM ThinkPad Full Dock II)

The thing works great. PCMCIA and all the ports were recognised by default. The docks IDE interface is a CMD 648, so you should enable the according kernel option (building as module didn't work for me), if you want to use anything else than a floppy in the docks UltraBay. Note that the interface will most likely be ide2 and ide3 then, so the docks UltraBay drive will be hde.

Power Management

The T41p is APM and ACPI capable. more coming...
