Dual Proc board

[CraigK]

I'm helpin my cousin set up a server/office computer. It's up and running right now but he has no time to really play/set it up so he asked me to help him. He wants me to add another disc drive which is easy enough, but he is having trouble setting up the dual proc part. He has one xenon chip in there right now, and he tried to insert the other xenon chip but there were some problems. I think the board didn't accept the chip or something like that (I'll have more info on sunday). I don't know what motherboard (more on sunday). everything else is menial except he plans on running XP Pro and WinME (Two Hard drives). the big question is If I put the 2nd chip in, do I have to set the bios on the board to a "dual proc" setup? or what?

As always, your help is greatly appreciated

I don't tnink Me will work with multi-processors. XP will. If there is an option in the bios turn it on. Does this Xeon processor support "hyperthreading"?

only windows NT, 2000, and XP-Pro (and the server variants) support multi-processor systems. you will have to upgrade to one of those operating systems before it will make use of the 2nd cpu...otherwise it just sits dormant

if the 2nd processor is installed correctly, it will show up in the BIOS during boot.

If XP(Pro) is already installed, you will need to go into Device Manager as well and update the driver by changing from 'Standard PC' to 'ACPI Multiprocessor PC'.

And again, there's really no point dual booting w/ 9X or ME, they won't make use of the 2nd CPU.
