Only one core showing in windows xp help
That's strange. I wonder if you have some inappropriate BIOS entry. (Is it
possible to turn off dual core support in the BIOS? I know that it was possible to deactivate ACPI, at least on mainboards that are much older than your A8N32-SLI.) I once swapped in an X2 CPU onto a system with a single-core CPU, and XP Home SP2 automatically installed the multiprocessor HAL (hardware abstraction layer), and told me that it was doing so. It worked fine as a two-CPU system afterwards. You can try switching the HAL manually: http://support.microsoft.com/kb/309283/en-us The short version: do a driver upgrade on the entry in Device Manager under System devices. On my machine, the entry is Microsoft ACPI-Compliant System. (I'm moderately sure that's the right one.) I have no idea what level of risk may apply, although MS points out that switching to an inappropriate HAL will make the machine unbootable (into Windows). The next level of fix would be to do a repair install of XP. (Back up everything first.) The ultimate fix would be a clean installation of XP, making sure that all BIOS settings were OK before proceeding. Unless you have a virgin system (no applications installed), that could be a lot of work. Address scrambled. Replace nkbob with bobkn.

Where is the second core? Doesn't WindowsXP have to be told in the beginning that it's either Uniprocessor or Multiprocessor system? Also,I remember hearing or reading that one of the differences between XP Home and XP Pro was that XP Pro had support for more than one CPU and XP Home didn't. Now that was a long time ago and lately this seems not to be the case. |

Only one core showing in windows xp help
I heard XP home supports either ONE dual core processor or ONE single core
processor while XP pro supports up to two single core or double core processors. In other words, XP home supports only ONE PHYSICAL processor, but if that one chip has two cores in it, it's okay and it see's it as two cores. If you install either home or pro on a motherboard where two cores, physical or not, exist, XP really should see both cores. But if you had only one core when you installed the OS and then changed that out for a dual core CPU later, THAT is when it may not recognize the other core without you doing some dinking or even reinstalling the OS. -- Scotter Tyan Thunder K8WE Dual Opteron 252s (2.6ghz) 4 gig Corsair XMS DDR400 RAM XFX 7800 GTX 256 w/VGAsilencerV3 500 gig Hitachi SATA 300 160 gig Seagate SATA 150 Dual Dell 24" wide aspect LCDs 550W Antec power supply X-Fi Platinum Soundblaster - "dawg" don't wrote in message ...
