LiveCD! Copy to RAM..?

Hitboxx · 04-03-2007, 10:52 PM

Hi Guys

I see this 'Copy to RAM' option at boot-up in a lot of live-CDs lately, what does it do? Ok I know it copies it to RAM, how much RAM is required for this? And does it so happen like say I have a single DVD-RW drive, I put in a live-DVD, copy to RAM, remove the DVD and insert some other DVD for back-up or something. Is this possible?

Some advice
Thanks

Yes, that's exactly what it does. Typically you need at least 1GB of RAM to use the copy to RAM option.

The SLAX LiveCD needs less than 400MB.

Other "less compact" distros will need more though.

There are floppy-based Linux systems that run from RAM in as little as 4MB.

A modern, reasonably full-featured system occupies a CD-R, so about 600-700MB is needed for the in-memory image, which is why 1GB is typically recommended.

Well, in my opinion, SLAX is pretty modern and full-featured. =P

DSL can ran from RAM with 128MB, but I am unaware of how full-featured that is. It's pretty popular though, so it can't be too bad.

The Floppy Linux distros tend to feel rather bare-boned, and probably only worth using on a very old system...

Thank you, that cleared my doubt
