The Question is:
Hello to one and all
I'd like a quick explanation if there is one, please...
The Lexical f$getsyi("hw-vers") returns a long string of numbers...
------------
CINDY >write sys$output f$getsyi("node_hwvers")
065500000000000000000009
CINDY >
---------------
I should image the 655 equates to my machine which is an AlphaServer 4100 5/600
8MB.
What does a 653 equate to??
Many thanks
The Answer is :
The contents of this field are platform specific, and the lower ten
bytes are not particularly documented -- this itemcode is intended to
return hardware version information, and is not particularly intended
to nor recommended for the acquisition of information that identifies
the hardware itself. To determine which platform you have, use of the
HW_MODEL or HW_NAME itemcodes would be more appropriate.
For example:
$ x=f$getsyi("NODE_HWVERS")
$ show symbol x
X = "04EE0000000000000000000D"
$ x=f$getsyi("HW_MODEL")
$ show symbol x
X = 1262 Hex = 000004EE Octal = 00000002356
The above example was from the following system:
$ x=f$getsyi("HW_NAME")
$ show symbol x
X = "AlphaStation 255/300"
The 4EE (hexadecimal) model code is derived from the platform and
the value that is returned by each particular Alpha platform is
registered within the Alpha Architecture.
A subset of the model codes that are registered with the Alpha
Architecture comprise the contents of the $ALPHADEF module, a
module whose contents are unfortunately not entirely current.
With Dynamic System Recognition (DSR), the contents of $ALPHADEF
will inherently be less-than-current because certain newer Alpha
systems can be recognized by compatible but older OpenVMS releases.
But unfortunately, the $ALPHADEF module found on OpenVMS releases
newer than various existing Alpha platforms (including OpenVMS V7.3)
has not been updated with the Alpha systems released prior to the
OpenVMS V7.3 release. The OpenVMS Wizard will request that updates
to the contents of $ALPHADEF be made.
