TP 3550 Expansion Unit - Trap 000D when undocking

Applicable to: World-Wide

Description:
I have a 700/720 ThinkPad that I sometimes connect to a 3550 docking unit. I installed an XGA card in the 3550. After configuring OS/2 for the card everything worked fine until I detached the 700/720. Now, whenever I try to boot from the system OS/2 returns Trap 000D (Internal Processing Error) messages and won't boot. Everything is fine if I re-dock the 700/720 to the 3550 and boot.

Solution:
Because OS/2 is configured to use the XGA card, it looks for the card before loading the drivers. After you disconnect the 700/720 from the docking unit, OS/2 is unable to find an XGA card, and therefore cannot load the video drivers. This is what is producing the error.
Before detaching the system from the 3550, you must run Selective Install from within OS/2 to reload the VGA drivers. Then, the next time you reattach the system to the docking unit you must run Selective Install again to load the XGA drivers (if you wish to use the XGA while attached, instead of VGA).
