What the toram option does is copy all of knoppix (700mb) to ram and run it from there. Needless to say you need a lot of ram to pull this off. I tried it last night with 1gig of ram and it worked quite nicely. The main advantage of using toram that I can see is that it lets you remove your Knoppix cd after booting up. You can then read data cd's or burn cd's from Knoppix if you are so inclined.

If you don't have this much ram there is also another new boot option: tohd. Instead of copying Knoppix to ram, tohd copies the image to your hard drive. The syntax of tohd is something like this: tohd=hda1 - at least that's what I gleaned from looking at the 9-5 changelog.

So people, try out these options and post your experiences, negative or positive, back here.

____________________________________
EDIT

Do not try the tohd option if you are using the ntfs file system!!!!!!!!!!

You may well bork your hd.

If you need to run Knoppix from the hd on an ntfs partition, copy the image from windows to the drive. You can follow the instructions for the poor mans install on the docs page.

I would like to get those files to add to Local Area Security. It is only 180MB and this functionality would be great for forensics in terms of being able to burn to CDs with L.A.S. in RAM. I would like to add this to the 0.4 MAIN release. . .

--The instructions handling this are in the boot.img file on the CD:
boot.img < miniroot.gz < linuxrc

--To get at that linuxrc file:
o Grab Knoppix CD, boot into runlevel 2

' mkdir /mnt/tmp '

( If you're already in Linux and want to operate on the ISO file:
-- mount KNOPPIX*.iso /mnt/tmp -oro,loop
-- cp /mnt/tmp/KNOPPIX/boot.img .
-- umount /mnt/tmp
)

o If running from CD: ' cp /cdrom/KNOPPIX/boot.img /ramdisk ; cd /ramdisk ' -- You can also mount a writeable HD partition and do this work there, obviously

o mount boot.img /mnt/tmp -oro,loop
o zcat /mnt/tmp/miniroot.gz >miniroot ; umount /mnt/tmp

o mount miniroot /mnt/tmp -oloop

--Now you can access the linuxrc file in /mnt/tmp, miniroot is an ext2 filesystem. Search for the cheatcodes. It gets rather complex from there. ;-)

--Side note, for anyone interested: Outside the boot.img miniroot, Other cheatcodes are handled on CD boot by /etc/init.d/knoppix-autoconfig ( < /etc/rcS.d entry < /etc/inittab.) On an HD install the /etc/rcS.d is markedly different.

Hi all!

I have a couple of newbie questions re: this topic...

1) Why is it so dangerous mixing Knoppix with a NTFS drive? I mean, what is it that happens to toast the drive? I just wanted to understand this a bit more.

2) Am I reading this right in that using the TORAM command you can easily install Knoppix to a hard drive? For example, I have two HDs in my machine. One has W2K and the other is totally blank. Could I install Knoppix onto this blank HD through this command, or is the procedure a bit more complex?

Thanks for your help and patience with my newbie questions.

1. My understanding is that Linux does not fully support writing to NTFS, so the risk is that whatever you write to the NTFS disk may not be readable in either Linux or Windows. Worse yet, I'd be concerned about corrupting the whole drive contents, but I don't know if that's valid. BTW, I understand that the new release of SUSE, due out later this month, is supposed to address many of the NTFS compatibility concerns, but I don't know the specifics. See the link below, where they claim: "SUSE LINUX 9.0 now also supports the NTFS file system used by Microsoft Windows 2000 and XP. Thus, users of all Windows versions without any previous Linux experience can install SUSE LINUX alongside Windows and migrate gradually. "

2. The purpose of TORAM is to run Knoppix from RAM. There is a knoppix installer for installing Knoppix to HD. There are a number of posts and threads relating to installing Linux to a second HD and keeping Windows on the first. Word search the forum, and look particularly in the HD Install section.

OK, Paradox posted the link to this thread, so here is an example of installing Linux to a second HD (note that I had some minor problems also :oops: )

and then there's this one:

Is it my imagination, or did 'toram' stop working in the 2003-11-14 release?

When I try to boot straight off the CD with the "toram" boot string, it takes 270 seconds! Also, I get no partitions on the desktop, and nothing runs any faster than normal.

Now this may well be because I have barely enough ram to run "toram" (778MB), but I thought it would run better than that! The only benefit I see to using "toram" is to free-up the cd drive.

Regards,

what's the ramdisk size on your Dell GX270?
If that is smaller than 1gig, was your "toram" operation truely successful?
what's the smallest size in order to run "toram"?

Booting tohd

Hello,
I am not sure if this helps, but using a company laptop with winxp pro as only OS (naturally HD is NFST), I used UltraIso to copy the ISO image to c:\knoppix.iso and when I want to boot from HD , I log in as Knoppix and add bootfrom=/dev/hda1/knoppix.iso and it works perfectly. If this helps, voila. It certainly works for me in liberating the CD drive and when using my usbflash drive formatted with swap, and home files, it saves wear and tear there!
