The standard 4.2 ISOs boot an i586 kernel not an i686 kernel.

Try the 4.2 single server CD and you might have better luck (it boots an
i686 kernel).

The upcoming 4.3 ISO set for the i386 arch will boot an i686 kernel by
default and require people to pass in i586 if they want to install on an
i586 machine.  This will solve the dd issue once and for all :)

How it will work:

For most users (everyone except pentium classic and VIA / Cyrix i586
users) it will be press enter as normal (or linux followed by any
switches ... just like now).  This will behave and use the exact same
type of kernel (built from sources of course) as the upstream provider.

For i586 users ... you would do:

i586 <Enter>

The above command would boot the i586 kernel and install on an i586
machine.  This is an option not offered by either the upstream provider
(or many of the other rebuild projects).

For rescue it will be the same .. for normal users:

linux rescue <Enter>

for i586 users

i586 rescue <Enter>
