Bug description:
Previous release livecd's were bootable by holding down option while
the cd was in the drive and selecting the "Windows" cd.
Trying this with the Meerkat beta desktop livecd image (md5sum verified) I
just get two numbers (1. and 2.) which look like
they should be labeling some text but there is no text visible and the
message to select CD-ROM boot type. Typing either a 1 or a 2 doesn't do
anything.
Googling revealed that some Windows beta iso images had the same problem
booting on Macs; apparently in this case it was an issue that the Windows
version had EFI support (and so didn't use the BIOS fallback) but was assuming
a newer version of EFI.
There were some other posts which claimed that it was that the iso image was
generated incorrectly (something having to do with ISO9660 versions).
Unfortunately, even though I develop software for a living, there is
nothing I can do to help debug this (except try newer versions) since
once I get to that message, everything seems unresponsive.
The upshot is that a useful thing which I did frequently in older
versions (i.e. boot the 64bit desktop livecd on this macbook) no
longer works.
