Nope. Due to the way that the APIC / SMP design is for IA based machines, this wouldn't be possible, or even practical. Imagine having two separate OSes trying to use the same memory address space, or the same peripherals... I can see it now... Win2k wants the mouse to go to the right, X wants the mouse to go to the left... you end up with a core dump, BSOD or reboot. > Are there "inexpensive" methods to make one's PC run a > second CPU (Something like a PCI-card)? There's a company in England (name escapes me at the moment) that produces basically an Alpha system on a PCI card. I contacted them at one time about building a monster machine with over 100 processors (you can get PCI bus extenders that are daisy chainable) and they came back with a quote that about knocked me over. At a quantity of 100 cards, I got a price break DOWN to US$5800 each. Needless to say, that project died a quick, silent cribdeath. Depending on your definition of "inexpensive", US$5800 might be what you're looking for. Sun also used to produce an ISA and PCI card that would allow you to basically put a Sparc in your PC. These cards are pretty rare anymore (I'd love to find one myself). They had the processor, Sparc system RAM, and I/O ports onboard... I believe they could use the PC's SCSI Controller or had one of their own. Solaris on Intel basically put hardware out to pasture. There are also various Transputer cards, etc. out there that would be interesting toys to play with, but they're generally $$$^X. --- Andy P.S. - If anyone has one of those Sun PCI cards for sale/trade, please contact me immediately.
