.kdfiles and boot start and Vista
Anyone been able to use .kdfiles -m in WinDbg with boot start drivers on Vista? After much wailing and gnashing of teeth I am thinking it can't be done. Anyone? I have seen some posts on this but they all either go no where or the people replying didn't read very well. Here is what I have tried. I tried using bcdedit to turn on the boot debugger. Here is my output from WinDbg: Waiting to reconnect... BD: Boot Debugger Initialized Connected to Windows Boot Debugger 6000 x86 compatible target, ptr64 FALSE Kernel Debugger connection established. Symbol search path is: From the kd prompt I set >sxe ld:mydriver.sys and the debugger promptly broke after all of the boot start drivers had been loaded?? The .kdfiles mapping to my driver never kicked. I am connecting WinDbg via NULL modem cable COM1 115200 baud. I also tried loading a checked build of WinLoad.exe...still no love. I can't seem to get the debugger to hook during boot. HELP? Anyone? I have seen several veteran driver devs ask this same question with no real help. If it isn't possible, it would be nice of someone to just say so. In my case this would sure save me a butt-load of time. Thanks.

.kdfiles for boot start drivers does not work with the new Vista loader.

Re: .kdfiles and boot start and Vista
Much thanks Doron! I was still beating my head against this one....saved me a bruise or two. Btw, I am guessing ".sxe ld:blah.sys" doesn't work either at boot start time? Bill M.

Re: .kdfiles and boot start and Vista
I don't know whether it is possible or not. However, based on some of the replies from certain ops, I would say that the safe assumption is that it no one who knows is going to say, for whatever reason. >>> xxxxx@sbcglobal.net 2007-04-19 18:22 >>> Anyone been able to use .kdfiles -m in WinDbg with boot start drivers on Vista?

RE: .kdfiles and boot start and Vista
Don't know, but I would trust your empirical evidence. OTOH, while the boot loader loaded the image, it has not yet called into the image's entry point yet, so if you have the symbols, you can set a bp on blah!DriverEntry or use the PDRIVER_OBJECT to find the entrypoint's address d -----Original Message----- From: xxxxx@lists.osr.com [mailto:xxxxx@lists.osr.com] On Behalf Of Bill McKenzie Sent: Thursday, April 19, 2007 4:24 PM To: Kernel Debugging Interest List Subject: Re:[windbg] .kdfiles and boot start and Vista Much thanks Doron!
