Nandblaster for XO-1.75

NANDblaster for XO-1.75 is identical in behaviour to NANDblaster for XO-1.5, so please follow the NANDblaster for XO-1.5 instructions, with the following precautions:

• use either an XO-1.5, XO-1.75 or XO-4 as the sender laptop,
• provide an XO-1.75 operating system build on USB drive to the sender laptop,
• avoid starting XO-1.5 or XO-4 receiver laptops, since although they will appear to complete the process, they won't boot the installed build, unless the build has a mixed architecture boot script, which is not included in current releases.
