What's the difference between ACPI multiprocessor and MPS multiprocessor?

If i enable the multiprocessor feature in Win200 will i be able to run on a single processor pc?
 
To my knowledge, ACPI stands for Advanced Configuration and Power Interface - power management. I believe you are confusing MPS for SMP, or Symmetric Multi Processing, which is the only type that W2K does. When people refer to multi processing, they are almost always refering to SMP on this forum.

As for your second question, I belive that W2K has to be reinstalled, but that there is a way around that. If you have the SMP kernel running and remove a processor, I am not sure of the results.
 
Actually i had w2k installed with only one cpu, when i installed my second cpu, w2k worked both cpu's, but i get hangs and stalls, and w2k has a hard time shutting down, so i guess i'll have to reinstall...
 
If I remember correctly, MPS was the older Multi Processors standard from Intel, the difference being of all processors sharing some of the same cache (386, 486 and old Pentiums), the latest REV being MPS 1.4 in some Pentium MMX MOBOs.
 
I just wanted to note, if you choose ACPI/MPS MultiCPU when you don't even have a Dual CPU mobo, I read 2000 will not boot. Choosing the MultiCPU loads a new Hardware Abstraction Layer (HAL) and requires a DUal CPU mobo.
 
We pulled a cpu out of our milti-proc system at work and didn't nitoce any problems, was only out for a day but it worked.
