Hi!
Does anybody know if there is a way to use WinDbg
kernel debugger extension (My own ones or existing
ones) with Compuware’s SoftIce Kernel Debugger?

Yes. There is a translator that processes them for use with SoftICE,
and Visual SoftICE can in theory use them correctly. I have never used
them with SoftICE, and I have had decidedly mixed results with Visual
SoftICE. They sometimes (pretty frequently, actually) just produce
output of any kind. I have no idea of why. For Visual SofICE, you just
set the path for extensions (SET KDEXTPATH) and then invoke commands as
!EXTENSION.COMMAND (i.e. - !kdxets.help).
Best of luck,
MM

Hi,
Thanks for the answer but my main focus is on SoftIce
(Not visual softice), I know that when you write “!”
on the command it tells you “debugger extension” but I
don’t know how to load such nor tell what is the path
and etc…

ALON:
The first thing you do is run whatever extension you wish to use
through the “KDExtension Converter” program (KD2SYS; an icon for it is
created under the Compuware Start Menu Item. It converts the DLL to a
driver.).
Reboot the system (to load the KD extension that is now a driver
If you start SoftICE manually:
NET START SoftICE
NET START
4. Type !? for a list of comands.
CAVEATS:
This whole thing really doesn’t work all that well, in my opnion.
These are the known limitations:
1. You must have and up to date NTOSKRNL.NMS loaded. Extremely bad
things will happen if you don’t.
2. No file IO in the KDX. If a command uses file io/ it will fail,
generally with no information at all. This makes a reasonably sized
portion of the standard KDX’s (kdexts) not only useless, but all very
confusing as you get no feedback. For example, you can not do things
like .dump.
3. Do not use exception handling in your KDX. They normally don’t
anyway, as DbgEng wraps each call for you.
Like most everything else about SoftICE, that this work at all is
nothing short of remarkable. They’re converting a user-mode DLL to a
system driver (without source), running it a ring 0 against a library
(or emulation thereof) that was designed for remote debugging. That
being said, it is also quite frightening and, doesn’t, in my experience,
work reliably enough to replace WinDbg.
If you have the option, I would strongly consider looking at Visual
SoftICE or just using WinDbg. It is a much, much more stable
arrangement, and uses the same engine as WinDbg, so KDX’s are usually a
problem (although even here things get a little hinky). If you are
interested, I can tell you how to set up your host and target so that
you can simultaneously run both WinDbg and Visual SoftICE. This is what
I do. It is actually amazingly easy and stable.
