Here's where I'll be keeping the tuning man page update until I
commit it saturday evening. I've already made some improvements.

Though I'm pretty sure it's available several places, I'm also pretty sure
it's a bit outdated :)

That would be wrong. We install ports where ever you tell the system to.

Hi all,
I am looking for the file "ddwg.ps" or "ddwg.pdf"
(device driver documentation).
Is it available on web?

One more question:
In the probe routines, the values of the hardware ports are changing from
one chipset to the next. Throughout the ppc driver, the regular macros are
used to access the parallel port control registers, but in the probe routine
it reverts to inb/outb, probably because it makes

Thank you for the answers. I will check out the NATd code and start there.
The code I will be writing is so similar to NAT so I can probably use this
code with minor changes.

According to SUSv2 the corect #define to use here is IOV_MAX, which
unfortunately we don't seem to define anywhere. Steven's Unix
