There are no single 32 and 64-bit versions. Debian has different ports for different architectures which are either 32 or 64-bit. You (as many people) are confusing "32-bit" with x86-32 (i386 port) and "64-bit" with x86-64 (amd64 port). But there are 32 and 64-bit non-x86 architectures out there, and Debian supports some of them too. >> If my memory is correct, for a computer to include 8GB of RAM, that is >> addressable by the CPU, the CPU would necessarily be a 64 bit CPU, to be >> able to address that much RAM.

Most 32-bit-only x86 processors starting from Pentium Pro (including Pentium II/III/4 and Athlon) support PAE. > You can choose what to use: 32-bits or 64-bits OS. An amd64 OS won't work on an x86-32 CPU with PAE support. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
