RE: Knoppix question

Knoppix boots w/ a lot of services on by default. Remember, it's meant for people to try out Linux and see what it can do. If you just need a LiveCD to test drives, use one of the lighter LiveCDs or build your own. Look at that frozentech website that has many, many LiveCDs on it. They each have their place. You could probably get away with using System Rescue CD LiveCD to test drives. It is around a 20-30MB download. Knoppix is also like a Swiss Army knife. Many uses, but you may never use the corkscrew or the leather punch.

Text only Linux should be able to run in 4MB, or even 1 MB. Or hey how about in 64KB? Or <shudder> even 16KB? Nobody will ever need more than 1MB of RAM... JMHO, Brian D.

Read the post. From version 3.3 on, Knoppix auto-detects and uses Linux Swap partitions if found. No key presses. If you want to alter the disk, as I said, you have to use "noswap" so that Knoppix runs without a swap file. If you have anything mounted on the drive, you can't repartition w/ qtparted or parted.

A crawl for an inchworm is far, far slower than a crawl for a Komodo dragon. I think Knoppix opening OpenOffice on a laptop with 96MB is somewhere close to inchworm slow. ;')

I've booted Knoppix on my laptop which only has 96MB RAM. I didn't touch any keys to do this. Now to be fair there is a swap partition on the drive and it may have seen this and used it.

Why waste all that effort in launching knoppix? Tomsrtbt is surely much faster loading and is tuned for such tasks.

I have taken old parts and assembled a test system, I would like to know if Knoppix will boot into 256 mb of memory only. No hard drive, no floppy. I am wanting to use it as a test station for hard drives, (checking if they are bad and fdisking and such). Thanks

RE: Lexar Secure Jumpdrives [and Linux support]
by Brian Densmore 28 Dec '04

On a new note. I contacted Lexar and told them I needed the software and they sent me the software for Linux, Mac and Windows. So there is a way to use the Lexar JD secure under Linux. Not that I would consider an XOR security algorithm secure. So Lexar encryption hardware does appear to be compatible with Linux. > -----Original Message----- > From: Brian Densmore > Sent: Monday, December 27, 2004 12:20 PM > To: kclug(a)kclug.org > Subject: RE: Lexar Secure Jumpdrives > > > > -----Original Message----- > > From: Jason Clinton > > > > ...

Well this is at least partly not true. Linux did recognize the device and both the fat16 partition and the encrypted partition. Unfortunately, I played around with it and couldn't delete the partitions and rebuild it from inside Linux. I also managed to delete all files on the drive and can no longer access the hidden partition in Windows. Although, Linux now sees it as one fat16 partition and on Linux partition. I may have to google or call Lexar to find out how to wipe of the hidden partition. So what I have now is one Windows usable partition and 2 Linux usable partitions. Strange, fdisk and cfdisk both have no problem is deleting the partitions and creating a new one and saving the new partition table. But, once I exit fdisk or cfdisk it goes back to the way it was before. Brian Densmore
