It’s been coming for a while, I know, but getting older is no fun. My target Win7 x64 system does not have a com port. Not one. Sheesh! I believe
that I can use a nice expensive USB debug cable, but has anyone ever tried using one of those USB->serial port things for debugging? Normally I would
think that it would be OK, but I’m not sure what is going on in the target machine under the hood. Just to clarify, I would like to use a usb serial
port adapter on a Win7 target machine. If the system normally boots and puts the USB/Serial port at COM3, for example, can I BCDEdit and do:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=“Debugging with Cable” /fastdetect /debug /debugport=COM3 /baudrate=57600
and run Windbg on my trusty old WinXP machine that actually has a real honest to God serial port?
Thanks!

Possible for the host machine, but not for the target. The kernel
debugger requires a genuine UART serial port at the traditional I/O port
addresses. Do you have a Firewire/1394 port? I find that to be the
best choice.

Have you looked well? Does the BIOS setup mention serial ports?
Many mobos have a RS232 header, though with no external connector.

OK, thanks. I’m still trying to get the 1394 cable situation resolved, but what about USB? Is the USB debugger cable the same thing as a USB data
transfer cable? Or at least, will it work? Thanks again.

A 1394 card costs a fraction of what the USB debug device costs, and 1394 debugging runs about 40x faster, and is much easier to get working and keep working.
Don’t use USB2 debugging unless you don’t have a choice.
Joe.

Indeed, and as someone mentioned earlier, check your motherboard for headers
for 1394. Sometimes they are there.
Good luck,

To clearly answer your question. NO, the usb debug “cable” is NOT the same thing as an easy transfer cable. And NO you cannot use an easy transfer cable to kernel debug a target over USB2.

I can’t believe that this motherboard does not have a 1394 port on it, but I don’t think it does. Lot’s of USB, lot’s of SATA, bot no firewire. I
think I am going to have to go USB. Argh!
Buy a card and plug it in. Unless of course you bought a motherboard without any slots…

You meant that as a joke, but this is not a motherboard I would buy for myself. It has 1 PCI slot, and a whopping 2 PCIe slots.

When I said buy a 1394 card and plug it in, I was dead serious.
If you have a free slot. Buy a 1394 card for it, and plug it in and use 1394 debugging.

That would be nice (one of the few features of SoftICE that I miss
(occasionally)), though if we’re making a list, I’d personally rather see
support for debugging hyper-v guests first.
My two cents,
