Hi, |

That script says it is specifically for 32-bit only, so I think you |
| 13 |
should be good. |

According to: |

It looks like that CPU type supports the amd64 instruction set but I |
| 19 |
don't think itt necessarily means you are using it in 64-bit mode. I |
| 20 |
think it would just simply not work at all if it's not valid for |
| 21 |
32-bit mode. |
