$ cat /proc/cpuinfo | grep flags
maka akan muncul hasilnya seperti gambar berikut ini:
Lalu, kita cari flag lm. Jika kita temukan flag ini, maka prosesor PC/laptop kita sudah support komputasi 64-bit, sehingga kita bisa menginstall sistem operasi 64-bit.
Catatan: lm singkatan dari Long Mode (64-bit mode)

Summary:
In id-slackware mailing-list, someone asked me about kind of processor he had, 32-bit or 64-bit. The answer is we can know it from cpuinfo by typing this command at console/terminal:
$ cat /proc/cpuinfo | grep flags
If you find lm flag (Long Mode) in the result, you have a 64-bit capable processor so that you can use 64-bit operating system.
