1 /ADDRESS
/ADDRESS=PFN-entry-address
Displays the PFN database entry at the address specified. The
address specified is rounded to the nearest entry address, so
if you have an address that points to one of the fields of the
entry, the correct database entry will still be found.
2 /ALL
Displays the following lists:
Free page list
Zeroed free page list
Modified page list
Bad page list
Untested page list
Private page lists, if any
Per-color or per-RAD free and zeroed free page lists
Entire database in order by page frame number
This is the default behavior of the SHOW PFN_DATA command. SDA
precedes each list with a count of the pages it contains and its
low and high limits.
3 /BAD
Displays the bad page list. SDA precedes the list with a count of
the pages it contains, its low limit, and its high limit.
4 /COLOR
/COLOR [= {n|ALL} ]
Displays data on page coloring. The following table shows the
command options available with the COLOR and RAD qualifiers,
which are functionally equivalent.
Options Meaning
/COLOR with no Displays a summary of the lengths of the color
value page lists for both free pages and zeroed
pages.
/COLOR=n where n Displays the data in the PFN lists (for the
is a color number specified color) for both free and zeroed
pages.
/COLOR=ALL Displays the data in the PFN lists (for all
colors), for both free and zeroed free pages.
/COLOR=n or Displays only the data in the PFN list (for
/COLOR=ALL with the specified color or all colors), for either
/FREE or /ZERO free or zeroed free pages as appropriate. The
qualifiers /BAD and /MODIFIED are ignored with
/COLOR=n and /COLOR=ALL.
/COLOR without an Displays the color summary in addition to the
option specified display of the requested list.
together with one
or more of /FREE,

5 /FREE
Displays the free page list. SDA precedes the list with a count
of the pages it contains, its low limit, and its high limit.
6 /MAP
Displays the contents of the PFN memory map. On platforms
that support it, the I/O space map is also displayed. You
cannot combine the /MAP qualifier with any parameters or other
qualifiers.
7 /MODIFIED
Displays the modified page list. SDA precedes the list with
a count of the pages it contains, its low limit, and its high
limit.
8 /PRIVATE
/PRIVATE [=address]
Displays private PFN lists. If no address is given, all private
PFN lists are displayed; if an address is given, only the PFN
list whose head is at the given address is displayed.
9 /RAD
/RAD [= {n|ALL} ]
Displays data on the disposition of pages among the Resource
Affinity Domains (RADs) on applicable systems. /RAD is
functionally equivalent to /COLOR. See the table in the /COLOR
qualifier description for the command options available with
/RAD.
10 /SUMMARY
/SUMMARY[=(option,...)]
By default, displays a summary of all pages in the system,
totaling pages by page location (Free List, Modified List,
Active, and so on) and by page type (Process, System, Global,
and so on). Also, provides a breakdown of active system pages by
their virtual address (S0/S1, S2, and so on).
Additional information is displayed if one or more options are
given. If multiple options are given, they must be separated by
commas and enclosed in parentheses. Available options are:
o /SUMMARY=PROCESS
Displays a breakdown of active process pages for each process
by virtual address (P0, P1, and so on), and of non-active
process pages by page location.
o /SUMMARY=GLOBAL
Displays a breakdown for each global section of its in-memory
pages by page location.
o /SUMMARY=RAD
If RADs are enabled on the system, displays a breakdown for
each RAD of its in-memory pages by location and type.
o /SUMMARY=ALL
Equivalent to /SUMMARY=(PROCESS,GLOBAL,RAD)
You cannot combine the /SUMMARY qualifier with any other
qualifiers, but you can specify a range.
11 /SYSTEM
Displays the entire PFN database in order by page frame number,
starting at PFN 0000.
12 /UNTESTED
Displays the state of the untested PFN list that was set up for
