Question Booting thru USB stick


Hi mates

good to C all u guys again.
okay

i am trying the feather linux on my usb stick 256 MB, basd on their documents i tried doing

dd if=bootusb.img of=/dev/sda1

and it will do well, but later when i am trying to copy the KNOPPIX folder, it gives me a error saying "no space".

the actual minitrd.gz and linux24 files will be occupying max of 1.1 Mb of space,

remaining space how to utilise.?

any suggestions>

basically i want to boot the machine which doesnt have HDD, FDD or CDD inside it. only USB port will be there..

any suggestions please

pudhi

syslinux also does the same, like occupying 1.4 MB and not allowing to write extra files.

please help

dd copies the data, but destroy the partition sda1. A second partition should be useful, but I don't recommend to dd a flashstick (I destroyed one with dd or was it fdisk ? ;-)

Will the installer not recognize the stick to make a "proper" installation ?

Uhm, all Distros I ever used had their own installer, including tomsrtbt (who is build to fit on a single floppy).
Sorry.

Hi fluppi
thanks for your support

now i got rid of this, by making fat16 partition (previous i formatted the partition as ext3)

then ran syslinux /dev/sda1, after this i copied all the files from feather linux other than ldlinux.sys

it works fine

Uhhh, RedHat focus now on Enterprises and big business.
Maybe dd the Knoppix-CD to USB Stick should work, but the space is not enough, and downsizing will be too time-consuming ?

A normal Installation with the minimum will work, BUT your stick will die shortly, due all log and temp files will be written on the stick who "just" can be written 10000 to 100000 times (sounds much but with a few writing every second done very fast) and writelocked will there be problems.

How about the following alternatives:
-Big CompactFlash as hda repacement
-Boot from network
-Customizing Knoppix ?
-Build a Linux from Scratch (= your own Distribution)

And maybe is an USB-Stick Linux distribution already out there ?

If you intend to run Linux from a USB Flash disk, it must run from a RAMDISK, or else your Flash Disk will be toasted, like fluppi said.

I made my own distro to run from a RAMDISK, it isn't that hard. The problem is that you are limited by the machine's physical amount of RAM, so you can't really get X or anything without running out of free RAM. This wasn't a problem for me, but you seem to want a GUI.

You could copy the contents of the Damn Small Linux disk onto your flash, and boot it with SYSLINUX. DSLinux is already designed to run from a read-only media, so you shouldn't have any problems with toasting your drive. Plus, it is small, only 48 MB.
