A very nice i/o board with 16 open collector outputs (capable of driving 5-40v) and 16 inputs Also has 2 16 bit cascadable counters (10Mhz clock) capable of generating interrupts. It is a PCI card, and emulates the Intel 8254 timer. It uses the PLX PCI-9050 PCI bus interface to map the 8254 style hardware and the i/o registers into the IO space.

Hopefully, this list will one day be obsoleted by DEVFS, but for now
|
|
this is the current allocation of device major numbers.
|
|
|
|
For local use, you are encouraged to use the reserved numbers.
|
|
|
|
If you intend the driver to be available, send email to the
|
|
hackers@freebsd.org mailing list to see about having a number
|
|
reserved for you.
|
|
|
|
The most "complete" version of this will be the one in FreeBSD-current.
