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. NetBSD 9.99 September 16, 2012 NetBSD 9.99
