The discs are designed to work under W95 on a 486SX machine running at 25Mhz and having a 128Mb HDD and 16Mb of RAM.
So either do as described by Phil, or run them under a virtual XP machine, or indeed a real XP machine.
Don't expect there to be any action taken to rewrite anything by Xpart, after all the discs still operate perfectly in their intended environment
