Here's what it says. Seems to be RAM related, but I can't make heads or tails of this stuff anymore. Linux, btw, but I don't see why it would matter.
no memory segmentation into low and high memory
up to 128TiB virtual address space per process (instead of 2GiB)
64TiB physical memory support instead of 4GiB (or 64GiB with the PAE extension)
16 general purpose registers in the CPU instead of 8
I found the store receipt: "AMD Athlon 64 Dual-Core 4400+". That looks like it might be a 64-bit processor.
I seem to remember the recommendation was to run 32-bit unless you had need for lots of RAM. If you ran 64-bits on low memory machines, it would run slower. I could be completely mistaken, but fairly certain most people go 64-bit only because it's a bigger number without knowing what it's really about. I mean, on the store shelf one says 32, the other 64. Of course a guy would buy the 64, right? It's only $50 more..
For someone that used to program in 80286 assembly language (Microsoft DOS), this stuff just whizzes over my head now. What happened..? My snowblower knows more about computers than I do today.
Oh heck - a little reading while I type this. I'm running 686-pae, apparently a 32-bit kernel. It seems all I need to do is install a different kernel (linux-image-amd64 - Linux for 64-bit PCs) to go 64-bit, but what could the reason to do that be? Even all of the software could be replaced with 64-bit stuff, but again, why?
Those are just rhetorical questions, but I would really like to know why Openoffice (aka StarOffice, LibreOffice) says it will load Access files, but won't load Tool Log... I'm guessing that Microsoft changes the format to prevent it from happening and I'm just out of luck.
Time for a bowl of Cheerios. :grin:
