Thanks so much for your response! A few mop-up questions below. Hope you
don't mind.

My apologies. I thought I'd researched this carefully before posting.
Should have cast my net a bit wider, I guess.

I notice that the rebaseall defaults (assuming I have them correctly) for
the -b and -o flags are:
-b: 0x70000000
-o: 0x10000
Was there some bit of information in particular that caused you to choose
0x61000000 and 0x20000, respectively, or was it a matter of trial and error?
(If you know of a good reference for windows's memory model and layout, feel
free to point me in that direction).

Okay, so with the -d0 flag, you're telling peflags to set the dynamicbase flag
to 0 on all specified files - meaning, I guess that these libraries and
executables should NOT be "randomly rebased at load time by the OS?" A naive
question: why wouldn't you want that to occur? (again, if the answer to that
question is too involved, feel free to point me to documentation).

And here the -t0 flag sets the "tsaware" flag to 0 on the specified files --
i.e., the executable/library should not be reconfigured as multi-user. Correct?
I note from microsoft's site that "/TSAWARE is not valid for drivers, VxDs, or
DLLs." But is there some reason you wouldn't want the .exe files to to be
mult-user aware? Other than the fact that on a standalone desktop PC, it wouldn't
really make much sense :-> ?

Thanks again for your help and patience! And again, a pointer to documentation
will suffice to answer my questions -- particularly if any or all of them would
require a treatise by way of answer ;-)
