[OSR-DETECTED-SPAM] RE: intelide.pdb not on MS public symbol server?

Those errors are probably normal. Many 3rd party drivers don’t have pdb’s
on http://msdl.microsoft.com/download, and spldr does not.

Good luck,

Subject: [windbg] intelide.pdb not on MS public symbol server?

Hi, I am new to driver development. I am trying to learn using windbg. I
installed win 7 32 free on VMware Player. I am using an example from DDK
that can be found in src\general\ioctl\kmdf. I want to set a breakpoint at
the Driver Entry. I set my symbol path as
SRV*C:\WinDDK\7600.16385.0\symbol*http://msdl.microsoft.com/download/symbols
; C:\WinDDK\7600.16385.0\src\general\ioctl\kmdf\sys\objfre_win7_x86\i386.
But, I can’t set the breakpoint because I get the message that correct
symbola aren’t loaded. I used the !sym noisy and .reload /f and found
somethnig interesting

How to solve the problem? Thank you all very much.

Symbols can’t be loaded until the module you’re debugging is loaded on the
target machine, so that’s probably your issue. If you want to set a
breakpoint on a module before it’s loaded you can set an “unresolved
breakpoint” with bu:

bu mydriver!driverentry

Yes, that solved my problem. Thank you Scott very much. I have lost 2 days trying to solve the problem, but without success. Thank you very much Scott.
