Hi all,
can anyone tell what is a ramdisk and why it is used and what is the meaning of the statement "configuring the kernel to boot from the ramdisk" and much more information on ramdisk
thanks..

http://wiki.linuxquestions.org/wiki/Ramdisk = what is it

2) why
http://www.tldp.org/LDP/sag/html/boot-process.html in my opinion to make this decompression and manupulation easier

3) for what reason, a ramdisk for a live cd ? or as a kernel parameter
pls specify your distro so others can be more helpful

thanks a lot for the reply aus9,
in my case, we are using MontaVista linux on FC4, we have loaded a Boot Loader and a kernel image to the target board PQ2FADS,now we want to have ramdisk image on the board ,, so collecting info about ramdisk and how it can be used and all ??
"configuring the kernel to boot from the ramdisk" i didnt get the meaning of this statement

and what is the difference between a RAMDISK AND CACHE ???

well without needing a link its this
a ramdisk is a virtual drive (partition) to allow a system to populate it

if you do not have a hard drive for example then you create a ramdisk as big as possilble I have seen entries can't remember where at the moment that have

kernel ///blah blah root=/dev/ram blah blah

a cache http://wiki.linuxquestions.org/wiki/Cache
