Dual -> Quad = reformat?

[Cogman]

Will I have to reinstall XP if I change out my Dual core for a Quad core? I know I did for going from a single core to a dual core, but I am hoping it is different from dual to quad. Thanks in advance.

Shouldn't have even had to do it for the single->dual core upgrade. You probably just needed to switch HALs.

I would imagine the HAL is determined at install time like Win2003. Meaning if it detects 2 processors it installs a MP version of the HAL. If it doesnt, well then it gets a single version.
There is a way to configure for the MP HAL even if the SP is installed after the install. But the procedure looked cumbersome on Microsofts website at the time I was looking at it.

I can verify in Windows 2003 if you add more cores with the MP HAL it will pick them up.

Windows 2008 doesnt have this limitation and I would guess Vista as well. You can switch between MP and SP and the OS will install the processors as you add them.

Yeah, I had to change the HAL on a Windows XP box and it was a pain. On top of that, I had lots of random BSOD's following the change.. so I ended up reformatting anyways.

let me get this straight

if you uninstall your processor from device manager / shutdown / remove the old and install the new / start your computer windows will not find the new proc and install the correct hal, is that whatt you are stating!!!!!

Did the switch, no sweat, it picked up the multiple cores without a complaint. Much easier then going from single-core->dual-core

Glad to hear it. I was planning on researching this tonight. 😀
