 Forums >>  Debuggers  >>  # soft-ice, s2k3sp1 and APIs breakpoints

Topic created on: June 2, 2008 08:39 CDT by nezumi .

recently I installed Driver-Studio 3.2 (Soft-Ice 4.3.2 [Build 2485]) on S2K3SP1 and found out that breakpoints on APIs became context-sensitive and now they work only inside context of the process where they were set-up. I solved this problem with I3HERE(I1HERE)/CCh(CD01h)

just wonder - if someone has the same problem and wants to know how to fix it? if so, I tell you details

All right, I'm dying here.. are you going to tell us? ;)

Softice BP's are already context sensitive to some degree in XP/2K, different from how they were in Win98.  How does the S2K3 sensitivity differ from XP, and what was it you did to solve the problem?

Cheers,
Kayaker

soft-ice works well with W2K (up to SP4) and S2K3 free 180-day trial. no problem at all! but the very soft-ice, installed on S2K3SP1 refuses to set global break-points. Patch 3.2.1 (the last official patch) doesn't help.

so, we just tell soft-ice: "I3HERE ON", "d CreateFileW" (for example). we're lucky! MS supports hot-patching, so every API function begins with 8Bh FFh (MOV EDI,EDI), so we just change 8Bh FFh to CCh 90h (INT 03h/NOP) and don't care to recover them every time. breakpoints become global! to disable a breakpoint we just change CCh to 90h (we can write a few macros for it).
