Sorry, we can't really do much about "No driver for XYZ".
All you can do is either
1. Write a driver or
2. Provide us with hardware

In either case there is no guarantee that a functional driver will
result.

> Write a driver
I do know nothing about how it works. A working linux driver exist,
but I don't/is lazy to understand the code.
I learned C, know how it works *a bit,* but I never practiced it.
But I ready to be a tester.

Understanding Linux code is equivalent to reading specs in old babylonian.

Just get the datasheet.

It is very hard to write drivers without hardware.

OK, you made me want to write it self.
Does ANY documentation to Plan 9 kernel exist in this world?

Deprecated, but... Thanks.
Add "actual documentation to the Plan 9 kernel" to the wiki's TODO.

Linux kernel have various documentation for its libs, for examle, for libata.
It helps to understand a driver and to write a driver (at least, I hope).
A Plan 9 drivers uses a functions, I don't know, #include a having no
documentation libs,
and you want me written a driver to device, which is MUCH more
difficult, then UART/RS-232.

1. You'll work on the source. Start with reading the source.
2. Documentation sometimes lies. Code never does.
3. There are tons of examples in the kernel source. Most of them end
with .c.

What is that device even for?

The source is so loooooooooong. I am still afraid a long code.

> There are tons of examples
For anything, but not for the thing I need, thanks.

> What is that device even for?
IDE interface: nVidia Corporation MCP55 SATA Controller [10de:037f] (rev a2)
Datasheet is unavailable (NDA, it is senseless, but it is), but the
linux driver exists and works.

hm, what about just adding this to sdide.c:^atapnp?

+ case (0x037f<<16)|0x10DE: /* nVidia nForce 55 MCP SATA (rev 2) */

The libATA Developer's Guide in kernel.org is almost as long as the
source of the whole Plan 9 kernel.

I exactly saw it before, looks like an universal hardware problem resolver.

But english language saves me from turning into a robot.

Clearly we are too newbie-friendly.

Clearly, this is not linux community. This is a lot of kind mans,
which are always to help fix or to write driver self.
Meanwhile, in gentoo conference a admin bans for saying, that OSS4
software have somthing looks like XML, in other one they hate you for
saying, that X11 is the hack of the times of ZX Spectrum, C++,
portage, paludis. 12309, huge'n'bloated software, needless
dependencies, agrh~.
Anyway, thank you for the welcome. This is important for me.

Funny how something which came out of #cat-v can be one of the less
hate-filled places on the net. :D
