Is it still necessary to disable this on later Omnibook models like the 430? I take it that you have to disable 32-bit disk access completely, and that disabling 32-bit disk write access, but keeping 32-bit disk read access enabled doesn't work, right?

It's actually not that the OB disk hardware doesn't support it, but rather it appears to be some weird conflict with the power management. Using POWER.EXE to dial power management back to either STD or OFF also seems to prevent the freeze, but doing that causes some other problems (like the loss of suspend/resume functionality).

Where is the OBCONFIG.DLL installed on your system?

I still need to verify that. I can probably find a few different versions of those files on and do some comparisons to see which ones differ and which are the same. I simply installed OBCONFIG.DLL into C:\WINDOWS\SYSTEM; that file appears to provide the OmniBook control panel, and that was running just fine.

The one I bought (which was still brand new and unopened!) came with MouseWare 7.0 floppies in the box, along with the necessary PS/2-to-serial adapter for use with the OmniBook. Thankfully, the floppies were still pristine and not suffering from any bit rot. I suspect the TrackMan would be pretty flexible about the version of MouseWare you use, and it may even be generic enough to function with any basic serial mouse driver. You would likely lose the ability to adjust the orientation or redefine the buttons, of course.

Background of the question are possible optimizations - some mouse drivers are smaller / better than others, but they might not work for the built-in mouse, if it uses proprietary hardware.

I honestly haven't messed with the built-in mouse under DOS much at all - it's clumsy enough under Windows. Smile But I would highly doubt that it would work with generic mouse drivers, since it's actually a 2-axis analog input more akin to a joystick (i.e. absolute positioning) rather than the relative tracking of a typical mouse.
