Does Every Operating System Need RAM?

In the event that you have a PC that the RAM has perhaps gone terrible on, are there any working frameworks that will work on the PC, at any rate to help you test and diagnose the equipment? Today's SuperUser Q&A post takes advantage of a vivacious talk on the subject to fulfill an inquisitive peruser's inquiry. 

Today's Question & Answer session comes to us politeness of SuperUser—a subdivision of Stack Exchange, a group driven gathering of Q&A site

The Question  ???????????

SuperUser peruser VusP needs to know whether there is a working framework that can work without RAM: 

Is there a working framework that can be utilized without RAM, particularly, the kind I can make a bootable blaze drive from and use it with my PC? This gets cumbersome, since booting is basically stacking the working framework in RAM. 

Note: I initially needed to think around a RAM-less working framework to check and check whether my smart phone's RAM had gone terrible (it doesn't boot yet shows a clear screen), however I like the way this inquiry has snowballed.

The Answer   !!!!!

SuperUser supporter agtoever has the response for us: 

Does each Operating System need RAM? 

A compulsory venture in the BIOS POST methodology is to check if there is RAM. Alternatively, it verifies whether your RAM is working accurately. So the solution for your inquiry, "Does each working framework need RAM?" is: No, not on this (IBM PC good) equipment. Likewise, for the rest of this answer, I will accept IBM PC perfect equipment.

Could an Operating System boot with flawed RAM? 

In the event that your RAM is flawed (and not by any means truant or broken), or on the off chance that you can (somewhat) supplant your RAM, you may have the capacity to boot utilizing the BadRAM orBadMEM piece patches. It obliges you to recompile the part (sounds simpler than it is whether you are doing it shockingly) and you can reboot, then tell the bit where your awful memory is. A pleasant clarification of the utilization of Memtest86/Memtest86+ and BadRAM/BadMEM can be found here. 

Can an Operating System boot without RAM and utilizing the CPU's store as RAM? 

The extent that I know, there is no real way to utilize your CPU's store as RAM with no RAM introduce on your framework (as is recommended by @philipp and others) in the remarks. On the off chance that there is, it would be pleasant to include it here. The main paper I could discover on the subject is this paper about Using a processor's store as RAM until the RAM is introduced. Not certain if (and how) it will function without RAM. The extent that I know, there is no living up to expectations code that boots a working framework on an IBM perfect PC. Any references to verification of-ideas, working code, or whatever else might be available is welcome and I will add it to this answer.

Will I get to the BIOS? 

The first notice's inquiry is a bit dubious if the portable computer has the capacity pass the BIOS POST. As @Tonny brings up, no working framework will help you toget to the BIOS. You enter the BIOS utilizing the F1, F2, F10, DEL, or ESC keys (contingent upon your image of BIOS). 

The most effective method to recoup information from the portable computer without RAM? 

With respect to the objective behind your inquiry, why do you need access to your smart phone? Is there still information on the hard-commute that you need to recuperate? In the event that that is the situation, it is far simpler to force the hard-commute out (see manual) and join it to an outer stockpiling gadget or straightforwardly to a desktop PC. Here is a pleasant manual for do simply that.
