The interface to the dma services (bus_dma) you can find at : http://www.openbsd.org/cgi-bin/man.cgi > http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/pci.html) > You can also look at the ISA section, because of the NEWBUS architecture an ISA driver is very similar to a PCI driver in many ways, e.g. allocating bus resources, setting up interupt handlers etc. A few articles on www.daemonnews.org can also help: NEWBUS intro (helped me a lot): http://www.daemonnews.org/200007/newbus-intro.html KLD (loadable modules) : http://www.daemonnews.org/200010/blueprints.html Good Luck Riaan _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
