I've just spent some time focussing on getting the IA-1's wireless keyboard working decently under Win98 SE. Thought I'd share my results for anyone else who's interested. These are the keyboard drivers/programs I've had success with:
Compaq Easy Access Keyboard Software 2.20.D2
Installs a control panel for mapping 8 extended keys to shortcuts (web sites or programs). Only six of these correspond to Internet keys on the IA-1. No volume control and no remapping of keystrokes.
Microsoft IntelliType Pro 2.11
Installs a control panel for mapping about 20 extended keys to shortcuts or functions. Only 3 of the IA-1's keys (Printer, Media and $) appear in this list, and the driver assigns random preset commands to the rest of the IA-1's Internet keys. Volume control with on-screen display works beautifully with no configuration. No remapping of keystrokes.
A very promising driver specifically designed to be customizable for any keyboard with extended keys. Was able to reprogram any key on the IA-1's keyboard to launch a shortcut, connect to a dial-up connection, control volume, perform a window command, or control an on-screen display. Perfect for those who just want to use the Internet keys for URLs or programs. JRkey can't, however, remap keys to other keys, which is a shame.
This is more like it. Keys+ can map any key to a command or to another key or key sequence. My main goal was to get working function keys and a Delete key and this did it. My 10 Internet keys now function as F1-F10, Printer now acts as Delete, Back and Forward keys now work in Internet Explorer, and volume control keys pop up the Windows mixer and do their thing. Would have been nice to remap the Cancel key to be a Windows key, but Keys+ is a program, not a driver, and can't remap certain system keys that Windows intercepts. But I otherwise can't complain.
Based on my experiences, I'd make the following recommendations:
If you wanted only functional volume control keys with a slick OSD, get IntelliType Pro.
If you only want your Internet keys to launch programs or web sites, grab JRkey.
If you want your F-keys and Delete back, plus the option to launch programs and web sites, get Keys+. Now that I can do Alt-F4 again, I can get some serious work done on this thing. :)
I'll send my Keys+ keymap file to IA1Hacking.com and ask the webmaster to post it for anyone who wants to save a bit of trouble.
