I'm considering buying IBM ThinkPad Dock II (Model 2877), to my ThinkPad T43. And have few questions to the users of both.
I would like to put some SATA controler in the PCI slot. I know it should fit (I will use flexible PCI raiser if it will not) , however I'm wondering what possible speed I can get. Is this full PCI (33 or 66MHz probably) slot? Or is there some kind of bridge between it and the thinkpad (in Dock, or in both dock and T43)? I guess, there is some bridge anyway, and it is shared by this PCI slot, and IDE controller (CMD 648 for the Ultrabay 2000 slot) and PCMCIA cards (second Ricoh controller probably, right?). Can it get full 133MB/s speed in both direction (or more)?
How about hot plugging and unplugging this dock? I am using Linux, so unmounting file systems etc, unloading PCI card and Ultrabay drivers, and disabling PCI should do the trick. Is there anything to remember when pluging or unpluging it on running T43? Will power to the other components (includin PCI card) go off, when I unplug T43 from it?
AFAIK there should not be big issue, as actually PCI is behind PCIe to PCI bridge (most of T43 interal chips are on PCIe, with exception of the Wifi/bluetooths and modem card only probably).
I was also wondering about actually architecture of PCI bus in T43 and Dock II. My current PCI tree looks like this
# lspci -t -v -n
| \-02.0 8086:4224
# lspci -n | egrep '1c.0|1c.2|1e.0'
00:1c.0 0604: 8086:2660 (rev 03)
00:1c.2 0604: 8086:2664 (rev 03)
00:1e.0 0604: 8086:2448 (rev d3)
Or with names

Ricoh is CardBus controller (for PCMCIA, PCCard; as Express Card slot independent from it and connects to the 1c.2 (PCI Express Port 3)). So I guess, ThinkPad Dock II will plug in just below it Mobile PCI Bridge (in 1e.0), as next PCI bridge, and there will be CMD 648 IDE controller, Ricoh PCMCIA Controler (my guess) and one (or more) more things depending what I plug into empty PCI slot there. It will essentially be sharing bandwidth and interrupts with WIFI in notebook. Right? Can anybody with Dock II, and PCI card show us some informations (like me above).
Will T43p (14.1 and 15" version) with 6 or 9 cell batter will work with this Dock?
I cannot find any manual for this Dock on Lenovo age, and IBM pages for it are dead.
I was searching for any discussion about Dock II, but only found page on thinkwiki.org
Thanks in advance.
