- Or engineer that added support for them didn't tell the group writing
- the documentation that they existed, or the product manager that
- requested support for them didn't tell the documentation group
- about them, etc. Use the Reader's Comments page to let the
- documentation group know what's missing.

-
- There is not a monolithic group in DEC doing work on ULTRIX. There
- is a group that tries to maintain a registry of all this stuff, but
- usually all they have is names and not function. Even then some
- groups go off on their own and don't register stuff.

- In general "options" get turned into -DOPTION-NAME options to the
- command lines that build the source parts of the distribution. What
- the source files do with them (if anything) is their business. What
- this means is that you can check the source files or include files
- to see if anything has an #ifdef OPTION-NAME. From that you may be
- able to derive the meaning of an option.
-
- >options BINARY
-
- I believe this is used to build kernel object files intended to be
- distributed in object format. Check the "Guide to Writting Device
- Drivers".
-
- >options NETMAN
-
- I believe this is part of the support for DECnet-OSI (Phase V).
-
- >options CDFS
-
- I'm surprised this one isn't in the Guide. CD File System. See
- also cdfs(5cdfs).
-
- Pseudo-device are harder to track down. Sometimes you can find
- manual pages that mention a particular pseudo-device as being
- necessary to include support for a particular kernel feature.
- Many times they're things needed to include parts of device
- drivers (X11 related stuff).
-
- Many of the pseudo-devices you'll find mentioned in the Chapter
- 4 manual pages, but not in a way that makes them easy to find.
- Try grep(1).
-
- >pseudo-device netman
-
- See NETMAN above.
-
- >pseudo-device fddi
-
- Probably needed to support the FDDI TURBOchannel adapter.
-
- >pseudo-device sl
-
- SLIP.
-
- >pseudo-device xcons
- >pseudo-device ws
- >pseudo-device tc
- >pseudo-device tb
- >pseudo-device pcm
- >pseudo-device gwscreen
-
- For the most part these are X11 server things. I think "tc" is include
- low level support the TURBOchannel.
-
- >pseudo-device cdfs
-
- See CDFS above.
-
- >pseudo-device msdup
-
- One of the V4 versions added for the DUP protocol used to communicate
- diagnostic information to MSCP and TMSCP servers. This pseudo-device
- includes that support in the kernel. See the fya(4) manual page for
- more information you have a KDM70 or HSC on the system.
-
- >pseudo-device xisoftdev
-
- Never heard of it.
