PC 32 bit & 64 bit

Postby c327 » Tue Dec 15, 2015 5:36 am

Is a newer store bought PC and its internal hardware that was originally built as a 64 bit PC backward compatible to a 32 bit Windows O.S. and 32 bit installed software etc. ???

As far as I know the 64bit hardware always support 32bits stuff, the limit is that u can´t go beyond de 4GB RAM limit using 32bit OS and software

32 bit, yep...but, can't really go much further than that though(i.e. to 16bit or other similarly ancient stuff).

a significant portion of software in the open market is still 32 bit and happily will run on 64 bit machines. some 32bit stuff doesn't play as well, but...in general it should work with minimal effort.

I think you can still run 16bit DOS on 64bit systems, however, I haven't tried recently...

I was able to do 16 bit through an emulation - I'm pretty sure I remember seeing that post-WinXP 16 bit is unsupported, and will simply not run. you'd need similar emulation as to what i did (like dosbox) to make anything 16 bit work on a 64 bit windows install.

Win 10 "64" still has the 'cmd' prompt, and can manage 8-bit or 16-bit processes within that 'window'.

But a 'compatibility' mode is needed for 32-bit programs. Some 16-bit programs also will fare well. 8-bit must be run from a command prompt. The OS may attempt to combine two command lines as one operation step, and kick itself in the teeth otherwise.

every conversation I've seen about 16 or 8 bit on a 64 bit install(whether xp, 7, 8 or 10) it will not work without 32 bit emulation - whether or not you use the command prompt is beside the point.

it's possible you'd have problems finding proper drivers for winxp 32-bit to run properly on a brand spanking new computer. no problems for 7x32 on, I would think. can't see a reason you'd want to run any newer OS (post xp) to run in 32-bit, though. maybe some legacy 32-bit programs that just don't run on 64 bit? but I think that has more to do with a newer OS structure being the problem rather than the exact cpu/platform architecture.
I guess you'd have to lookup the motherboard make, and see if there are xp 32-bit drivers out there for it.
