# HARDWARE

The `mppb` driver supports the following hardware:

PROMETHEUS
  Matay Prometheus. Manufacturer 44359, product 1.

# HISTORY

The `mppb` device first appeared in NetBSD 6.0.

# AUTHORS

The `mppb` driver was written by Radoslaw Kujawa <radoslaw.kujawa@gmail.com>.

# BUGS

The hardware does not support DMA to host memory.

The Prometheus does not support repeating of PCI transactions, instead if the PCI card demands a retry of transaction, it returns value 0xFFFFFFFF. This is currently not handled by the `mppb` driver and will confuse some PCI card drivers.
