  That's odd. My computer has a 110M ESDI with an Ultrastor 12F controller.
It runs 32-bit access with no problems. On the other hand, the controller
responds to many of the IDEINFO type programs. Maybe Windows thinks it's an
IDE.

  ???? IDE drives are only using a fraction of the power available to them.
With their full 16-bit parallel access, you are limited only by the bus
speed. I wonder if there are any drives that really tax the bus, yet.

  Does anyone know if there is going to be a 32-bit version of IDE for EISA
or even local-bus??
