Windbg Serial Console messages during Install via CDrom

WINDBG
1

Hi.

Is there a way to enable a WinDBG debug session with
with a client during the install phase of a CD ?

I use windbg in kernel mode to work on drivers
through the serial port ( /debug /debugport=Com1
/Baudrate=115200

I’m working on a addon SCSI component that is
installed
with the “F6” Add HBA option on a diskette and the
client
craters and I can’t see any console messages.

Thanks JD.

This is sort of described in the WinDbg Documentation under “Debugging
Techniques\Advanced Debugging Techniques\Debugging Windows Setup and OS
Loader.”

That’s for the hint.

Unfortunately, that describes modifying items on the
target disk
(assuming you get that far) in safe mode, then you
essentially
setting up the debugger much like you would editing
the boot.ini.

JD:

I’m confused. What is it you wish to do then. To the best of my
knowledge, you must install the checked build version of NTLDR/SETUPLDR.
I believe (but do not know) it would work if you either (1) booted from
a CHECKED build CD; or (2) burned your own CD with one of the
aforementioned loaders.

See my article http://www.osronline.com/article.cfm?article=264

Basically, you have three options:

  1. Make a new CD with the modifications you need
  2. Run the install from Windows, modify the data copied to the disk
    before the text mode setup
  3. On Windows Server 2003 you can press F8 (when it prompts for F6
    which you also need to do)
    this will enable the debugger with the following settings:

on 32 bit systems: /debug /debugport=com2 /baudrate=19200
on 64 bit systems: /debug /debugport=com1 /baudrate=115200

The article gives you the details, and other tips on debugging in the
install environemt. Note: none of this works on Vista!

Martin, That procedure assumes
you have Windows already installed
on the target system ( unless I missed
something).

Jd,

You are correct, that is why you want to do the steps from my article I
mentioned in the previous post.

Com2 ? for win2003 32 bit … That stinks.

I only have 1 serial port, and F8 does nothing
with that port when I tried.

I reconfigured the BIOS setting to define the single serial port
to COM2, and I still can’t attach to the machine with windbg .

I selected the Enterprise version when the CD starts.

Have you tried this recently ?
I get no debugger response during install.

12

I have not done it lately, look on your install disk for txtsetup.sif. Open
it (it is a text file) and find “SetupDebugOptions” if that is not present
F8 does not work.

At that point find a cd burner, and burn your own with the “OsLoadOptions”
set to what you want.

Here is the current settings from a
image I down loaded from MSDN :

SetupDebugOptions = “/debug”

OsLoadOptions = “/fastdetect /noguiboot /nodebug”

In the txtsetup.sif.

Yep, and /debug used to default to the settings;

/debug /debugport=com2 /baudrate=19200
