Subject:  [VOICENWS] OS/2 Kernel Updates on IBM Testcase

From: "Michele Della Guardia" <michele.dgatlibero.it> 

Try the new OS/2 SMP-UNI  kernel updates on IBM Testcase ! Note that this
code is experimental!

  -> URL: ftp://testcase.boulder.ibm.com/ps/fromibm/os2/

[Moderator's note: As always these are not officially supported by IBM
unless they tell you to use them.  Please send any followup to
comp.os.os2.bugs on usenet.  Also note that files are only on IBM's
testcase for 2-3 days, so if you want to try these get them now.   Make
certain you back up any files replaced and don't try these on a production
system.  Read any readme file before applying any changes.  If your system
is working well, and you have no problems addressed by these updates, do
yourself a favour and don't mess with this.  You have been warned.       

These testcase kernels contain fixes since xr_e002/xr_m015/mcp/acp.  The
UNI and SMP files are for WSeB/ACP and the W4 files are for post FP15/MCP
versions, including eComStation.

Here are the latest changes in this version, as posted in the readme file. 
(See the Readme for a complete listing):

Bug Fixes:
  Fixes from earlier "dated" kernels:
    03/15: Chgfileptr (seek) ops may fail on FAT, particularly on a vdisk

  Fixes to problems that exist in released code:
  0315   revision 14.088f
    PJ28472   Trap 000e in THEArena_Get running theseus/4 (may also be in
0311)

Here is a listing of new features added to these testcase kernels since
they have been released.  Most, if not all of these features should
already be in the ACP2/MCP2 releases:

New function:
    1) Support for >64m memory using int15 func e820. Note, this support
is
       enabled ONLY for Intel Pentium Pro or later, or non-Intel
Pentium-class
       machines. This is done in an effort to prevent problems on older
PCs.
    2) The presence of \os2\boot\os2norev.$$$ suppresses the display of 
       internal revision during boot.
    3) Adding "EARLYMEMINIT=TRUE" to config.sys will allow device drivers,
etc.,
       access to the memory above 16mb early in boot. Previously, this was
only
       available after DD and IFS init was completed. This has various
       implications when enabled:
	  a) AHA154X.ADD may do bad things to your system. Don't even ask.
	  b) There may be some settings of HPFS386 cache that are incompatible.
    4) Trap messages will now give the module name instead of the device
name.
       For example, "Exception in module: CLOCK01" instead of "Exception
in
       Device Driver: CLOCK$". 
	***change from 0220/0223: Traps in 32 bit code now show the modname, too
    5) Systems with a 486SX chip running FP15 will function correctly.
Note,
       they will NOT work with ACP or (necessarily) on MCP.
    6) SESDD32 will now work correctly (I hope) for both uni and smp
    7) All process dumps should now be considerably faster. paddr(all)
dumps
       should take about 40% less time and others around 80-90% less time.
    8) EXE names will now also be displayed in alt-f2/alt-f3 processing
(note
       that CMD file names, e.g. MPTSTART, will NOT be displayed, only
cmd.exe)
    9) alt-f4 is like alt-f2 plus it pauses after displaying each names
(does
       not pause after BASEDEV= or PSD=) and, by pressing F1, allows you
to
       skip loading/running the file displayed.  Alt-f5 is like
alt-f4+alt-f1.
    10) The dump formatter (in dfxxx.zip) should be faster and also work
on
        dumps >= 2gb, which was not formerly possible.

 2002/01/02:
    Support for 16bit filesystems with >2gb file support (e.g.the
forthcoming
    >2gb dump support ifs)

 9/13/01
    11) If you also install the enclosed clock01.sys to \os2\boot, you can

        add "CLOCKSCALE=x" to config.sys. The choices for x are 1 (the
default,
	which is the old behavior), 2, and 4. The number represents a scale 
	factor for the frequency of clock ticks. The theory is that CLOCKSCALE=4
	will speed up some apps (maybe Netscape and/or Java). ]
