Will the newer iprocessors work with Windows 98 SE?
CPU -- yes
RAM -- no, if more than about 1GB.
Better to USE Microsoft Virtual PC to RUN Win98SE.I agree with Computer_Commando as for I have run into issues with multicore & Multiple CPU's and older OS, and in Virtual PC 2007, which is what I use, all older OS run correctly within. ( But games for Win 98SE wont work too well with virtual GPU which is like a low end 2MB videocard simulated. )

I ran into an issue where Windows 98 although ran on a multi-cpu system, would not address the extra CPU a while back when I acquired a dual-cpu motherboard. I would assume that multi-core CPUs would probably fall into the same category. I ended up having to make the upgrade to XP to get use of the power of both CPU's. I then went with the first version of Virtual PC... might have been 2004 which cost money back then, but has since become free from microsoft in version 2007think of it like asking orville wright to fly a 747 jumbo. first thing he ASKS is "what the h$%% are all these gadgets???" just find an old computer if you WANT run old oses {PENTIUM 3 800mhz >1ghz 1gb>1.5gb ram} for fast win98 > winme
