Just found a computer in my school dumpster & to my surprise it works. As the computer boots, it says
Pentium S CPU at 90 mhz, so the computer is a pentium right? But when I run Microsoft Diagnostics it says the computer is a 486DX. Why is it reporting this?

My guess is that a 486DX is the highest processor MSD was programmed to detect given how old DOS is. But I could be wrong.

Spot is 100% correct!
If you want a small program that will detect the CPU correctly download SNOOPER

... well... you could always open it and have a look... lo-tech answer I know, but it works.
Perhaps it's an old version of MSD - like the one that shipped with Win31 (1992)
My 6.22 version correctly reports my lowly P1 processor.
Syschk is a great little utility for examining and benchmarking your system, small download, shouldn't be hard to find.

The sad thing is that the school system through away a pentium 90 PC. That sucks! You would think a school system would offer it to a student or donate it to a charity. A pentium 90 isn't a bad machine.
Ugh.

I dont think 486 dx2's are not bad machines but I found one in a dumpster at the college I attend. It was a huge tower pc. Could not find a monitor in the dumpster though. It was working when I plugged it up, loaded with Windows 95 & ran decently. I like the machine. It is such a waste just tossing them out. I remember going into a local thrift store & they had at least 50 desktop computers stacked on top of each other for $45 a piece. They were 486SX I believe. No doubt they got them for a little of nothing, maybe for free. Computers are so odd. They depreciate like crazy.

If you really want detailed info about your PC download SysCheck from www.syschk.com. It's new so it detects even the latest hardware.

a pentium 90 its a different socket7 than a 486dx and sx, it takes a special heat sync, and the processor is larger than the pentium class socket 7's and way larger than the 486DX/SX's Sometimes MS Windows 9x versions work on them, sometimes they don't.
I guess thats why the socket 7 class pentium's came out.the socket 7 class started with a CPU speed of 100... I believe.
the Pentium 90 class was a "class of its own"

If I remember correctly, the Pentium 90mhz systems were a socket 4 category proc and 486dx 2 chips were a socket 5. If it reports a pentium on boot its a pentium. Computers didn't report how fast they were on bootup until the Pentium chip architecture arrived. So it looks like you have a pentium. Look inside the case. If it's a socket 8 computer them you have a legend. You can get something called a slocket (not made up) for the socket 8. With the slocket you can put a P-II in them (max speed for them depends on the brand). It's and adapter changeing the socket into a slot hence the SLOCKET. Happy trails and crack that case :).

I think that Dark_Sword has little bit wrong Pentium 90 is on socket 5 and socket 8 is for Pentuim Pro. If its Socket 8 www.danbit.com have an adapter so you can put an Celeron on it check it out!
