http://www.symmttm.com/pdf/Bus/an_br-pci-vme-software.pdf It's not available in source code format I have written a device driver for FreeBSD, standard BSD open-source license. I don't have anywhere to post it for download, but will send a tarball (54K) of the source code files to anyone interested. It will probably work on NetBSD and OpenBSD with a bit of fiddling. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
