Wow. What a great resource! I found this forum while doing a Google search, looking for a way to get my new KVM switch to work with my IBM laptop and docking station.
I have a T42 and a ThinkPad Port Replicator II. I have 2 other machines, and wanted to put them all on a KVM. Tried a couple of the Belkins, but they are absolute garbage. You loose the keyboard and/or mouse when switching between machines (among a long list of other problems), and its not cheap!
After reading numerous reviews about IOGear's KVMs, I gave one a try. Its the PS/2 version:

I assumed that the keyboard and mouse PS/2 ports on the back of the Port Replicator would work, but they did not. I plugged the keyboard and mouse directly in to the docking station and they worked fine. IOGear support told me there was a problem with IBM and/or the docking stations. Based on notes I found here, I went out yesterday and bought a USB to PS/2 adapter at Fry's:

It works perfectly!
When I first booted the laptop using this adapter, it took a minute for it to recognize the mouse (using a cordless Trackman wheel). Again, based on a note I saw here, I had already changed the BIOS "Boot Mode" parameter from "Quick" to "Diagnostics" (with 2gig of memory, that initial memory test takes about 3,000 years!). Once it picked up the mouse, it worked fine. This morning, I changed the BIOS back to "Quick", and it still works fine. I'm a very happy guy!
I still can't belive how good this works for the price. The Belkin setup was about $200 ($110 for KVM, $30 for each cable set), while the IOGear setup was only about $60 ($55 for the KVM, $6 for the USB to PS/2 adapter).
Thanks again for everyone's input into this thread and forum!!!!
