Installing LFS on a ThinkPad T41p

---

Graphics

internal, AGP: ATI Radeon FireGL T2

You have to choices: xorgs radeon driver or ATIs fglrx driver. The xorg driver works fine, but doesn't support DRI. Also, support for a docks or port replicators DVI port is theoretically available, but practically not possible. This is being worked on.

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

The drive works pretty fine with the kernels standard IDE CD-ROM driver. You can burn CDs using cdrecord in ATAPI mode. Alternatively you may use ide-scsi and treat the device as a SCSI drive.

I didn't have success trying to enable hotplugging. Using ibm-acpi you can get events for the UltraBay eject lever, but i didn't manage to make hdparm unregister the IDE device. On my system it executes the command giving no error but afterwards the IDE device still shows up in /proc.

Ultrabay 2000 ZIP Drive (in docks Ultrabay 2000)

Works great using the kernels ide-disk driver.

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

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

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...
