64-bit seems to be working perfectly on my machine with stagexnu. Chess, Java6 and Lightroom 2.0 all ran fine in 64-bit mode. First time ever on my box ;-)

 

Also, the technique of using the EFI partition is applicable to setups which can run vanilla kernel as well as machines like mine which can't, which means it's greater than the scope of this thread. I think, however, I'll wait until the devs ok a release of the bootloader before I create a new thread with the howto.

 

Er... you might want to reread my post.

 

No, only Core Solo or better can run vanilla kernel.

ok, here's the thing:

 

The following is required to run vanilla kernel in 32-bit mode:

 

- Family 6 processor

- XD / NX - Execute Disable

- PAE - Physical Address Extension

- HPET - High Precision Event Timers (mobo feature)

- SSE3 - Streaming SIMD Extensions 3

 

The following is required to run vanilla kernel in 64-bit mode:

 

- All of the above, plus:

- SSSE3 - Supplemental SSE3

 

If there exists a 64-bit proc which meets everything except SSSE3, -legacy flag would let it boot in 32-bit mode.

 

It's up to you to figure out if any given CPU and mobo will work. If in doubt, just try it.

No, it does have XD, so that's not the reason. But Celeron D 320 is NetBurst architecture not P6, so THAT is the reason it can't run vanilla.

 

But why I can't find it on my BIOS maybe because the motherboard doesn't support it ?

Possibly. But that CPU does have XD according to wikipedia at least.

 

Well can I know that from CPU-Z ?

 

Edit: I've seen it on wikipedia:

XD bit (an NX bit implementation): supported by 3x0J, 3x5J, and all Intel64-compatible models

but mine is 320 only.
