	Intel 80486 - Wikipedia, the free encyclopedia
		The Intel i486 (also called 486 or 80486) is a range of 32-bit scalar Intel CISC microprocessors which is part of the Intel x86 family of processors.
		The 486 has a 32-bit data bus and a 32-bit address bus.
		With regards to the 486 system platform, early 486 machines were equipped with only 16-bit and 8-bit ISA slots.

	A CPU History (Site not responding. Last check: 2007-11-02)
		The 486 was the first to have an integrated floating point unit (FPU) to replace the normally separate math coprocessor (not all flavors of the 486 had this, though).
		The 486 chip was the first processor from Intel that was designed to be upgradeable.
		The 486SX was, of course, slower than its DX cousin, but the resulting reduced cost and power lent itself to faster sales and movement into the laptop market.

	486 processor (Site not responding. Last check: 2007-11-02)
		The 486 processor (or 80486 processor) family was introduced in 1989 by Intel.
		The 486 processor had two versions: 486 SX with no math co-processor and the standard 486 DX versions.
		The more advanced versions of 486 such as 486 DX-2 can run at speeds of 50, 66 and 75 MHz, and then 486 DX-4 can run up to 100 MHz.

	CPU-INFO.COM, x86 Processor info you need to know!
		The difference between the SX and the DX 486's was that the DX version had an integrated numeric co-processor and the SX version was "co-processor less".At the start of the 486 lifecycle, the SX and DX productions were different.
		AMD had copied Intel's design and the 486 they produced were exact clones en therefore 100% compatible.
		Initially the 486 worked at 5 volts but later this was decreased to 3.5 volt.

	486 dx/33 upgrade to 486 dx2/66 CPU [Archive] - PC-Media Tech Forums
		I already tried 1 486 dx2/66 cpu with a heatsink on so I can't see if indeed it was a 486 dx2/66 and it continues beeping when I power on.
		Early on, there were a lot of different manufacturers making the 486 processor (even AMD!) for Intel because Intel alone couldn't meet the demand for the hot new CPU at the time.
		My present 486 dx/33 256K cache, 32 MB ram Win95 can start up in 3 minutes and I am done with my email from Hotmail within 5 minutes not bad compared to my son's Pentium III which takes about the same time to start up and close.

		Older 486 Win 3.xx pc's are capable of a lot more that one might expect, they can be made into great web surfing and e-mail machines, small buisness machines, and much more.
		If you are running a 486 DX/2 66 or less, I recommend MSIE 3.03 - Netscape 3.03 and Opera 3.62 as your choice browsers as they run pretty fast on 66 mhz machines.

	Kingston's Turbo Chip 133
		TurboChip is a high-performance and convenient solution to increase a computer's performance 250% over its current 486 processing speed to provide the power necessary to run today's popular multi-tasking computing environment.
		Many 486 computers use ZIF (zero-insertion-force) sockets with a lever or retaining screw to make removing the CPU chip quick and easy.
		Benefit: TurboChip 133 is designed to upgrade a large installed-base of 486 systems with 5-volt motherboards and the regulator allows the energy conserving 3-volt Am5x86-P75 processor chip to execute commands from the motherboard.

		In the 486 case, its clock multiplier factor is fixed, i.e.
		Not all 486 motherboards have 40 MHz clock configuration and is not guarateed that this overclock works.
		BTW FrozenSteel, Cyrix made a 486 compatible chip called the 486DLC that fit in 386 motherboards, the main difference was that it used 387 FPUs and it only had 1kb of L1 cache.

		The most significant difference between the two generations of processors is that the 486 originally contained an integrated math coprocessor that allowed the computer to run more demanding software.
		Intel later introduced SX and DX versions of the 486, as it had with the 386, but while the 486 DX still contained the math coprocessor, the SX model didn't.
		A separate hardware upgrade, known as the 80487 SX, is required to upgrade the 486 SX to the same capabilities of the DX model.

		The 486 DX CPU is essentially a 386 processor combined with a 387 math coprocessor on a single chip.
		Note: Avoid the 486 SX, which is a 486 DX minus the math coprocessor.
		The PC industry expected the successor to the 486 to be called the 586, but when Intel discovered that it couldn’t copyright numeric names for its processors, it dubbed the new product the Pentium.

		The 486 is very similar to its predecessor, the 386.
		Main differences are an optimised instruction set, an on-chip unified instruction and data cache, an optional on-chip floating-point unit (FPU), and an enhanced bus interface unit.
		The 486 processor has been licensed or reverse engineered by other companies such as IBM, AMD and Cyrix.

		The 486 was capable of 20 MIPS performance, and contained certain features (such as pipelining) which had previously been found in mainframes.
		What the 486 really did was continue the imperceptible shift in thinking that the 386 caused for the PC segment.

		Be careful when you overclock such old CPU.I had an 486 DX4 80 once, and i got it to run at almost 120 Mhz.
		A friend of mine got a 486 DX2 66 to run stable at 110 Mhz, but then he used a much larger fan than usual.
		A 486 DX I would imagine runs on a multiplier of 2x with 33Mhz FSB.

		P rating at 60Mhz would be 100!!!) also my "super 486" machine had a UMC board at 60Mhz, that was the one with PCI and VLB, had a 2Mb VLB graphics card, and I had a Cyrix 5x86 running in 2x mode for 120.
		My first overclock was an IBM 486 DX-50 that I took to 66Mhz.

	Difference Between SX and DX on the 486 Platform? - Futurelooks Community Forums
		The difference between 486SX and DX was that the DX contained a built-in math co-processor, while the SX did not.
		The difference between the DX and SX was cache.
		While the DX line supported no L1 cache and up to 128KB of L2 cache on the motherboard, the SX supported NO L1 or L2 cache at all, making it somewhat slower than its DX counterpart.

		When we say it converts it into a 486 66, we really mean it!!!
		Your 386 DX 40 becomes 486 66 MHZ, tests have been made and we measured the CPU speed with different programs.

		Unfortunately, there is a small problem with just calling CPUID to find the CPU information, and that is: If the CPU you are running on does not support CPUID, it will crash (or, as the OS likes to call it, an "Invalid Instruction Exception").
		Relax, though, because the process (and appropriate source code) to find out as much information as possible from any given CPU type is here, in flow-chart form (this assumes you are using at least a 386, which is a moot point as any compiler you'll find nowadays will require at least a 386 processor)
