Hi Henk and Phill,
The alternate installer can install with less RAM than the desktop
installer, but the difference is smaller than I expected for Xenial in
my IBM Thinkpad T42 with Pentium M:
224MB (desktop) <---> 208 MB (alternate)
I had hoped that it would work with mem=192M, but no. Let us focus on
the great advantage: the alternate iso is within CD size. (It is
slightly too big right now: 704 Mibibytes.)
See the attached spreadsheet.
Best regards
Nio
