It changes both the model (DS2072->DS2302) and shows the bandwidth option (300M BandWidth), this on rev 2 hardware.

Can't you also just use a Linux Live-CD/DVD like Knoppix or similar as an alternative? No installation required.

--- Quote ---A live CD, live DVD, or live disc is a complete bootable computer installation including operating system which runs in a computer's memory, rather than loading from a hard disk drive; the CD itself is read-only. It allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. Live CDs can run on a computer without secondary storage, such as a hard disk drive, or with a corrupted hard disk drive or file system, allowing data recovery.

Might be better to use linux live CD, you can install programs to it, they will be installed to ram. And when you power down all will be gone and back to M$ land you go ;) So save the files to usb or other media before shutting down.
Live CD tools that mess around with HDD will make changes to you windows system, so just don't use them. U can't do it by accident.

Probably, the OS is least of my problems, I can use an raspberry, or my olimex a20 for that if an vm is not usable.
this on the other hand:

I have it lying here, but not sure what of the connections are for jtag, maybe I will find it on the ftdi datasheet though, but many have used it for jtag, so I don't understand why it's so difficult to find the pinout, my google-foo is expiring..
If the card at all is compatible with urjtag though..

I can't tell for sure yet since I don't know enough about it: I just tried some keys of a DSO that has the same production week as mine
and I got "license unavailable"
so it seems a memdump IS needed for every a-series DSO
