Website Errata / System Requirements
On this page;
There is the following text next to i386:
"The first architecture, and not strictly a port. Linux was originally
developed for the Intel 386 processors, hence the short name. Debian
supports all IA-32 processors, made by Intel (including all Pentium
series and recent Core Duo machines in 32-bit mode), AMD (K6, all Athlon
series, Athlon64 series in 32-bit mode), Cyrix and other manufacturers."
I believe this is no longer accurate. Debian no longer runs on / or
supports the AMD K6 series. It should be specified that a K7 or later is
required to run.
