Sorry if I wasn't clear.


I see your point george but they are reverse engineering and the Itanium is getting scrapped, trying to find the news links for ya. They dont want it to be excatly the same so they are walking it backwards and taking a different spur off of AMDs design as they dont want to be labeled as "copycats" when they already are. Sorry but AMD has all the glory for 64 bit and intel is following their lead as they have no ther choice.


Intel's tactic is perfectly understandable Rob as Itanium is a RISC processor and wouldn't be able to run 64bit CISC applications in its/their full potential. I don't blame them for doing so. At the end - as Intel has a lot more recources for R&D than AMD - I believe Intel will dominate 64bits as they have with the 32bit area despite AMD will be more experienced.

Since day one of this thread i've been looking for a manufacturer's site that used to sell a PC built around a PIV 3.0 GHz OCed at 4.0 GHz , water cooled. This PC loaded XP from an NVRAM - if I recall right. XP were up in 5 to 8 seconds.
Apart from this it was sold with 4gig DDR RAM , three 17" TFT screens , a Parhelia graphics card and many more features. It was sold for 3.500

The entire machine booted from NVRAM? Wow, well, I guess I can believe that being there was 4GB worth of sticks in there. Which would also explain the speed in loading... but also, with a machine running at 4GHz, there would need to be an immense power supply. (I know, mine just fried along with the motherboard)

I doubt it is 5 secs though unless they are talking about the server or media center edititon.

It was a very fast NVRam the one that booted the machine. I also had thoughts about it. I mean were was the registry kept and what if a virus was suddenly all over the disk and had to reformat ?

NVRAM is what I think will eventually replace the slow hdd. A system's performance is only as good as its slowest component. Although much has been done to improve throughput, a mechanical assembly can't come close to the performance of a solid state-based storage. I wish companies would put more effort into this. Of course, it would mean the end of hdd's as we know them now.

The registry would be kept in NVRAM as would all other writeable data. There are no disks. If a virus entered to the extent that it caused too much havoc, the NVRAM would merely have to be cleared (just like "regular" RAM). Depending on the type of NVRAM and quantity, this could take several seconds :)
Re-loading your applications would be at the speed of your mechanical media (CD-ROM, floppy).
If you have lots of RAM, try making a RAM-disk and load some of your apps into it. You can hen get a glimpse of what types of throughput are possible. Of course, the RAM is volatile so it will be lost with power down.
Here are a couple of links for further info:

I used to use Ram disks since the days Atari ST was my main computer.

I know that for clearing up , say , an EEPROM chip , you have to have it for several minutes 15 to 20 in aq dark room under the black light lamp. Is this the procedure for NVRAM ? If it is , then it will be hard to reformat it. If it works like a ram disk ( I used to have a 512 mb ramdisk on my PC , out of the whole 1,5GB ram ) and I could format and reformat it. But , is this the case ?

Ginogsm,
Yep. The EEPROM methodology is not used. NVRAM is like FLASH memory where a programming voltage would be applied to erase (or write) memory locations. I've used memory chips that have "shadow" ROM. I.E. there exists a parallel layer of RAM over a non-volatile memory. With that method, you can store whole sections of data to non-volatile memory, while operating out of very fast RAM.
I'm not sure that "formatting" would be the proper method (or even nomenclature) that would be used with NVRAM based storage. One reason for formatting a hdd is to be able to locate/identify a physical sector on a spinning platter. This is not an issue with NVRAM. You don't need your operating RAM "formatted" to run apps, as an example...
I'm not extremely familiar with RAM-disk interfacing, but I imagine that the reason for "formatting" a RAM-disk is to make it transparent to the OS's we have today.
What, me worry?

i used ram disks for years and my ie is set up to run of one it stores all the temp files and my cookie files, it greatly speeds up the internet as its not having to use the hard drive to store web page info that you would access a lot. like going back a page or scrolling down a web page no longer uses the hard drive and due to the mem running so much faster than a hard drive.

nearly ten times faster will post a screen shot to prove.
Work in progress :)
