Configure windbg for IA64 Itanium m/c through com

Hi,

To capture driver messages i used to connect the com port of host and
target machines and when my driver is pumping the debug messages they
will be captured in windbg on host machine. So even if my driver
crashes i still have the trace.
This is well in 32bit ix86. When we boot the target we specify to come
up in debugger enabled mode thru boot.ini file.

How do i do that in IA64 itanium2 machine ?
I have a HP Rx2600 machine that is configured for multi boot into
-HP-UX
-Linux and
-Windows 2003 Enterprise server

As these machine provide multi boot from NVRAM+EFI environment i
cannot use boot.ini. Most importantly i dont want to disturb the
existing multiboot.

Is there any method to use COM port to capture debug messages ?
or any other method to capture trace messages onto the other machine.

You must be able to specify the same BOOT.INI switches in the EFI environment.

Thank you all, it worked.
The problem was COM 1 port is marked called "serial B" on rx2600.
Did it raise ur eyebrow ?

could specify the options in EFI and able to do kernel debugging thru other mechine.

Thanx and regards,
