David - I have made a boot disk that should work. I cant test it as I dont have T2 hardware.
only run it on a system with a blank harddrive as it will format it as part of the install.
You may need to partition the disk using fdisk with another dos boot disk first
(I got one from here:-

PM me your email. and Ill send you an image file of the bootdisk I made for this.
