I have old single core Pentium 4 511 processor yet, on Windows 7 in recent years, indeed it was frequently overheated above 70 grades. https://ark.intel.com/content/www/us/en/ark/products/27453/intel-pentium-4-processor-511-1m-cache-2-80a-ghz-533-mhz-fsb.html I have read user reviews and ones say it supports 64-OS, the others - does not work with it. Indeed this official specification shows processor support Intel 64, and 64-bit instruction set. I want to know what it means exactly - what is peculiarities of 64-bit Windows OS installation and work on this generally 32-bit processor? And the next question is whether I can use docker on this processor in 64-bit Windows OS (7,8)? If not how to resolve this inconsistency in Windows OS? And can I use Docker with Linux-64 OS on this processor and how smoothly it could work?
