The reason I was interested is that the CPU supposedly can run 64-bit code, it is apparently just the UEFI that refuses 64-bit. But one can install 32-bit and then reconfigure Guix later on to use 64-bit, so it is not important. > > a DVD with an untreated Guix > > git master could not be booted but very likely due to an error with m= y > > external DVD drive (it often does not work) >=20 > We could start a separate endeavor in private for diagnosing that. > (My other sport besides ISO 9660 is burning flat round things.) >=20 > :D Burning is not the problem. ;) This slim laptop has no DVD drive itself and my external USB DVD drive works only sometimes and might have required even more patience. Booting got stuck waiting for the DVD drive which continued to make noises, as it often does on other machines when it has a bad day. This was not a problem with the DVD or the image, but with that DVD drive of mine. I will test Danny=E2=80=99s patches on my Macbook and on the Ideapad. > > I will try a current git master Guix iso built for 32-bit next.
