1) Couple of bug fixes in pnpdump to correct the skeleton
   configuration file generated.
2) New feature to allow user specified IDENTIFY-FORMAT in
   isapnp IDENTIFY output.

pnpdump (now v1.12)
-------------------
1) Fixed bug introduced in previous version: CONFIGURE in
   skeleton had logical device id, but should be vendor id.
2) Low true, level sensitive interrupts would put +L in
   the skeleton, should be -L of course.

isapnp (now v1.13)
-------------------
1) Allow the user to specify format of IDENTIFY command using
   the new IDENTIFY-FORMAT command. Default is as previous
   versions:
   "Board %b has Identity %8 %7 %6 %5 %4 %3 %2 %1 %0:  %v Serial No %s [checksum %8]\n"

isapnp.conf.5
-------------
Updated to include documentation on the new command IDENTIFY-FORMAT.

man2html
--------
Updated to handle clash in keyword names IDENTIFY*.

Changes since Release 1.11
==========================

Summary:

1) Alpha ports added, specify -DALPHA in Makefile.
2) The default behaviour is now to preserve existing hardware
configuration settings for both pnpdump and isapnp. See
ISOLATE in the isapnp.conf.5 manual page on how to reset the
hardware configuration.
3) Two features have been added allowing common configuration
scripts across groups of machines (see CONFIGURE in the
isapnp.conf.5 manual page):
3a) Devices not found are skipped rather than aborting the
script.
3b) Serial numbers may be specified as instances of the
cards found, for example #1 means the first card with
the given Vendor Id, #2, the second etc.


README, INSTALL
---------------
Minor updates now that ISOLATE and pnpdump don't reset board
configurations by default.
Added note on using DOS port with loadlin to allow compiled-in
device drivers.

README.DOS
----------
Added comments about DPMI servers if it doesn't run.

README.initrd
-------------
Corrected: using initrd doesn't remove the need to have PnP
device drivers as modules, it just allows the root device to
be PnP. If you want to use compiled in drivers, run the DOS
version before using loadlin to boot.

FILES
-----
Added man2html.

pnpdump (now v1.11)
-------------------
1) Reformatted
2) Alpha port changes added.
3) Removed ioperm calls as iopl covers it (Except Alpha).
4) pnpdump no longer resets the board configuration registers when run.
5) Made serial number output unsigned, except for -1.
6) pnpdump.8 manual page updated.

isapnp (now v1.12)
-------------------
1) Now allow board serial number to be specified as #1, #2 etc for the
first, second etc boards of each type.
2) Removed ioperm calls as iopl covers it (Except Alpha).
3) Fixed bugs in handling IRQ settings.
4) Ensure board_found is 0 when starting ISOLATE, warn if not.
5) Missing boards now skipped, remaining boards still configured.
6) Alpha port changes added.
7) ISOLATE changed to take an argument - CLEAR or PRESERVE (default).
   [CLEAR was the old default (only) behaviour]. Determines whether
   existing configuration information preserved.
8) Made serial numbers unsigned, except for special case -1, which
   means no serial number.
9) isapnp.conf.5 manual page updated for the above, plus improved
   documentation for READPORT.

Changes since Release 1.10
==========================

Major new feature: DOS port added to allow dumping of settings used by
Win95/DOS. If you don't have djgpp, use the DOS binaries in the binary
