Hi,

I am designing an embeded computer product, using a Pentium-M processor
board
with a Flash Disk (for holding the runtime Image and loading it into the
Processor Memory).

The operating system (kernel) will be Linux.
I do not have a hard disk (or any other storage device) as part of this
system ie no storage device to write to.

I have been told that Linux will not be able to wok without a File System,
ie without a hard disk.

Is anyone aware or able to comment with certainty on this subject ??

Would the Linux Operating System be able to be configured to run without a
hard disk or any file system ?
    If NO, Is there a way of tricking Linux to think that a File System
is present, but rather in memory ?


I thank you in anticipation.

Cheers

Phillip
