== IBM ThinkPad Dock II ==
The IBM Dock II (Model 2877) is the most feature-packed dock IBM sells. In addition to supporting all the features of the [[ThinkPad Mini-Dock|Mini-Dock]], the expansion capability of the Dock II can transform a regular Thinkpad into a full blown workstation with multiple monitors (PCI video card), higher fidelity audio (PC Card audio), and additional storage [[UltraBay|Ultrabay 2000]]. These expansion features are not supported by all Thinkpads, therefore the Dock II does not support as many Thinkpads as the [[ThinkPad Port Replicator II|Port Replicator II]] or [[ThinkPad Mini-Dock|Mini-Dock]].

=== Features ===
* everything the [[ThinkPad Mini-Dock]] has
* 1x half-size PCI card slot
* 2x Type II (or 1x Type III) [[CardBus slot]]
* 1x [[UltraBay|Ultrabay 2000]] slot

===Pros & Cons===
* Positives: Expansion capability
* Negatives: Cost ($399), internal fan is loud, large, less compatible
* Compatibility: X20/30, T20/30/40, R50/R51 and A20/30 Series notebooks.(does not support the A21e/22e, R40/40e/50e/51e or X40/41).
* Warranty: One Year

==PCI Slot==
Note this is a full height/half size and not a 'low profile' slot (the PCI card on the pictures below is "low-profile", but "half-size" cards also fit in the Dock II). Separate brackets are required for low profile PCI cards. Normal cards will not fit.

Many use the half-size PCI slot for peripherals like secondary video cards, TV tuners, audio cards, etc. This is considered by many to be the highlight of the Dock II, and is a feature that few other docks have. The Dock II does not support AGP or PCI Express. The Ultrabay 2000 slot can be used to connect other IBM peripherals, such as second hard disks or CD/DVD drives.
Potential owners of the Dock II are often concerned about compatibility and recommendations of video cards. See the [[#Compatible Video Cards|compatible video cards]] list below for more information.

Recommended kernel modules for using the slot are: dock, pci_slot, pci_hotplug and acpiphp. The pci=assign-busses kernel parameter is also recommended.

''Dock II owners: anybody tried to shoehorn a larger card in? ''
''Also: has anybody managed to use a PCI video card to drive the built-in LCD?''

Dimensions are up to 18 x 12 cm:

{{gallery_end}}
In order to use a larger than "low-profile" card with the Dock II you can use a PCI riser. This means you might have to build a hollow support base for the dock, but it will allow you to connect any card. These PCI risers can be found at places such as [http://mini-itx.com/store/?c=8#p1908].

===Video Cards===
The PCI slot is most often used for installing video cards to allow for multiple monitors. This feature is especially useful for anyone that requires visualizing a large amount of information, including stock brokers, artists, etc. Due to the slow PCI bus, gaming is generally not improved much by external cards.
One of the chief concerns of low profile video cards is whether they support the monitor setup you desire. As more monitors these days are LCDs, quality DVI support is essential. Additional concerns include driver support, ability to hot-swap (add or remove the thinkpad without rebooting), and noise/heat.
====Quality DVI & Widescreen support====
One way to work around the [[Problem with DVI throughput|limitations]] of the docks DVI pass-through port is to use a PCI graphics card which features a DVI port. Note that while this probably will work, the performance of the PCI graphics accellerator will be poor because of the limitations of the interface.

Also the newest ATI video drivers for both Linux and Windows are known to not have limited resolution support on the external DVI port anymore.

====Hot Swapping====
'''It is unknown whether hot swapping is fully supported.'''
Check the [http://forum.thinkpads.com/ thinkpads.com forum] for more information.

====Noise/Heat====
Since the [[Dock II]] has been reported to be a bit noisy, some people have taken to unplugging the fan inside (or possibly replacing it). While this likely voids your warranty, it may be necessary if you really want it quiet. Adding a video card increases the heat inside the dock, and may likely have a fan on board as well, meaning it will increase the noise level. While adding one of the below video cards is likely well within the thermal limitations of the dock, you should take into consideration the noise and heat it may add.
<BR><BR>
The fan is located inside the power supply and is 40x40x13mm / 5V. To reduce noise the fan for example can be replaced by any 12V-fan, that starts when operating at 5V (many don't). An instruction can be found in [http://thinkpad-forum.de/thread.php?threadid=16417&hilightuser=1133 Thinkpad-Forum] (German).

===Other PCI Cards===

==Ultrabay 2000==
In contrast to the Full Dock I the Full Dock II has a full featured (= hotswap capable) [[UltraBay|UltraBay 2000]] slot.

Note to T4x owners: [[UltraBay|UltraBay 2000]] is an older Ultrabay technology, not compatible with the [[UltraBay|UltraBay Slim]] in the T40/T41/T42/T43 lineup. Many [[UltraBay|UltraBay 2000]] accessories are available on [http://search.ebay.com/ultrabay-2000 Ebay].

The docks IDE interface is a CMD 648, so you should enable the according kernel option (compile it into the kernel if loading as a module doesn't work), 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.

==PC Card Slots==
Nothing special: 2 additional Type II slots. This may be helpful if you need a certain PC Card only while docked (e.g. a second GBit NIC), or if you have 2 PC Cards that physically won't fit into one pair of slots at the same time (e.g. 2 WLAN cards or 2 [http://www.villagetronic.com/e_pr_vtbook.html Villagetronic VTBook Video cards] ).



==DVI pass-through==
LCD monitors are getting larger and higher-resolution. Currently, DVI based on 165MHz TDMS transmitters can only (officially) support 1600x1200x32 at 60Hz, which is the resolution of your average 20" non-widescreen LCD. IBM's driver support for this resolution through DVI ports on docks has been inconsistent. Also in Linux you might experience [[Problem with DVI throughput|problems]] even with this resolution and IBM officially states that the pass-through DVI port only supports resolutions up to 1280x1024. Read [[Problem with DVI throughput|our page]] of information on how to solve these troubles.

Please be aware that not all Thinkpad models will support DVI output with a Dock. Apparently, X and T2* models do not. Please add other models if you know about them to not support DVI.
