Try F2, Del, INS or other keys on boot to try. DO NOT CHANGE ANYTHING WITHOUT EXPERT ADVICE OR COUNSEL

Gurus - will a 945GC chip support PAE?

Only Intel 946 and above support PAE.
Some PowerUsers are under-rated.

That made me smile - thanks.

It all comes down to architecture, and hardware. Allow me to explain:

What this means is the greater numbers of bits that can be processed at any given time, the greater the number that can be represented. Binary Numbers are read from right to left, with each successive digit representing a larger number. For example, the binary number "1111" is the number 15. It is calculated as follows:...

...As you can see, 64-Bit is fr, far larger than 32-Bit in terms of maximum addressable space. Heck, I don't even know how to pronounce the number in bytes!

FYI, if you're curious about it, HexaDecimal (Hex for short) is nothing more than a "human readable" form of Binary, with the numbers 0-9 and A-F representing the numbers from 0-9 and 10-15. It's easier to write down "0xFFFF" to represent 65535 instead of "1111 1111 1111 1111"

Hope that cleared things up for you...
That is seriously the best in depth explanation of the 32bit vs 64bit address issue.

Would you mind if I use this as an explanation to this question?
With references, of course.

I added to your table, hope you don't mind:

I think it must have been something you said, or didn't say.

Peter,

Excellent write-up!

In case you were referring to 32-bit microprocessors, you might be interested in this tidbit:

32-bit - Wikipedia, the free encyclopedia

Quote:
Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory. The external address and data buses are often wider than 32 bits but both of these are stored and manipulated internally in the processor as 32-bit quantities. For example, the Pentium Pro processor is a 32-bit machine, but the external address bus is 36 bits wide, and the external data bus is 64 bits wide.[1]
Nice site!
Hope you dad is keeping well.

Lived in Pretoria, worked at Bloemfontein a while back.
Love RSA, relatives in CT...
Miss the vors on the braai, biltong, etc.

By all means. If you have the time to do so, why not create a Tutorial about it?
