Solved Ram/OS

[bassfisher6522]

Can you install an OS with out any ram in a PC/laptop?

If there is no RAM you can't even start up that machine. You'll never make it past POST (Power On Self Test)

RAM is a necessary component, just as much so as the processor. There's no way the installer could actually run or do anything without memory to reside in.

Files (and that includes programs/drivers/data) can only execute and/or be modified whilst they are in RAM.

Come to find out; this laptop I have (Dell) has 256 MB RAM integrated and a slot in back/bottom for additional RAM.

That might be enough to set up a DOS, OS/2 and WfW (Windows 3.11) or even some Linux flavors but certainly not se7en

always wondered

Dell used to embed a memory chip in some of their laptops. I never was fond of the practice, because if that chip developed memory errors, the laptop was useless...and you couldn't swap it out.

Hi there this is FALSE -- the O/P asked whether an OS could be installed without RAM (any OS - not specifically W7).

Some mother boards have a mini-os built into the BIOS (Gigabyte Mother boards for example) which can connect to the Internet so you can flash upgrade the BIOS BEFORE booting up the OS.

Although BIOS is also really memory too, by RAM I assume you mean the conventional RAM that is installed in the memory slots in a PC.

RAM is only required if the O/S needs more memory than is available in the BIOS.

In theory you should be able to run W7 from a BIOS and just use peripherals such as HDD's for saving user data etc.

Anybody who can remember the first IBM PC's should recognize that the original OS was in the COPYRIGHTED IBM BIOS and the non IBM PC manufacturers had to "reverse Engineer" this to be compatable with the then standard of PC's --the IBM PC.

(The BIOS was IBM BASIC - so you didn't even need the BIOS to have been compiled in C or whatever first. A built in interpreter generated the correct machine instruction codes).

The ORIGINAL IBM PC's didn't boot from a disk - although it DID have disk drives.

The "compatable" PC market started with booting from disks and had to "replicate" the IBM PC.

Note also that a BIOS OS can access peripherals so if Disk drives etc were made available to the OS operating in a BIOS then of course user data could be created and changed --no RAM required either.

A decent BIOS actually has a lot of functions in any case for acessing Disk drive etc etc.

Hopefully this clears up misunderstanding about this question.

Hopefully this clears up misunderstanding about this question.

It actually does quite the opposite, and I don't really get the purpose of your post, other than to wave your e-wang around.

Seriously. The context of the thread was that the OP didn't realize the laptop had embedded memory in it. What's the point of nit-picking to this level, other than to belittle someone else?

I guess if we want to nit-pick, I'll state that your comment is false, and SledgeDG is correct. The BIOS is an operating system, but the computer won't move past the POST...which where the BIOS ceases to be the operating system. The BIOS will run enough to politely tell you there's no memory installed. Many laptops won't even go that far, as they will immediately tell you to install memory before it could even attempt the post.

I don't mean to single you out, but we aren't playing Technical Trivial Pursuit here. There's no reason to belittle someone else and muddle the info given at the same time.

Hi there

I wasn't actually Belittling anybody's thread but just stating SCIENTIFIC FACTS.

The only reason a BIOS will post No RAM is if its programmed to look for any at power on.

A BIOS can contain ANY program the writer cares to program it with.

I'm certainly not playing "Technical tag" or whatever -- but merely attempting to explain that a BIOS CAN contain an OS without any external memory requirements.

The fact that specific PC's will post an error if there is no RAM is NOT an inherent property of all PC's -- but just how that particular BIOS is implemented.

It's also not intended as an insult to attempt to correct what is technically incorrect.

Please read the SPIRIT of the post rather than assume any attempt to correct errors is confrontational.

I'd suggest reading the "spirit" of the thread. You may not have intended it to be belittling, but it came across that way, and wasn't relevant to the OP's question.

I'm not trying to sound like an ass, but if I was the OP, I'd be way more confused after reading your post than I was at the time of the thread start.

Since I'm nowhere near perfect I'm always willing to learn. (but I'm not from the Game Boy generation either) So please explain to me, where my statement was wrong?
Fact is: if there is no RAM, you won't make it past POST. Whether you'll get a series of Beeps or a screen message depends on the BIOS itself. But no matter what BIOS you have, without RAM no OS.
I even pointed out a few OS that could be installed with his build in memory.

The rest I just take as given information irrelevant to the case at hand.. DeaconFrost already pointed out what needed to be said so I'll leave it at that.
