The isa_irq_pending() function is also an example of an ISA dependency.

This driver works quite well on five different > busses - what does the HP machine do that is different? For one, it hasn't got any ISA busses. Secondly, the Diva comm board is memory mapped. In sioprobe() we assume I/O. It's also a multiport board and we also don't seem to have the framework yet to just tell it the characteristics of this board as the Linux driver has. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe p4-projects" in the body of the message
