[comp.sys.hp] brc and powerfail questions

notes@misty.boeing.com (Notes admin. (J. Sadler)) (12/20/89)

Looking at the manual entry for brc it say's:..." and loads any programmable
          micro-processors with their appropriate scripts."

Can someone tell me in which manual it talks about these "programmable
micro-processors" and "scripts" ?

Also the powerfail script executes a /etc/dasetup.  I can't find anything on 
it in the manual either.  Anyone know anything about it ?

I don't know much about dasetup except that it downloads the file
/etc/UMUX.download into the microprocessor on each 6-channel multiplexer
configured into the kernel.  You will find it not only in /etc/powerfail,
but also /etc/inittab (on Series 800).  I suppose this does sound a bit like
the "micro-processors" and "scripts" in the brc man page description...

This is intentionally a general statement, so as new hardware is
supported we don't have to go back and change the manual.  Read /etc/brc
for specifics.

One of the Series 300's optional Floating Point Accellerators has to
have some microcode downloaded at boot time.  The "script" is the
microcode.  I would look in the manual shipped with the FPA to find
documentation.
