This means that an empty file, or a too-small file will not be acceptable. An easy way to create a file of a chosen size is to use the dd command like this: dd if=/dev/zero of=pippo.txt bs=32768 count=1 This copies 1 block of 32768 bytes from /dev/zero to pippo.txt. You will have a nice small zero-filled file. - FChE -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE7mLKWVZbdDOm/ZT0RApbJAJ95KQ8MZtTB8pkeYBlDZointLP0HQCfZLT1 /WU5F50UAHfNpCGu2ezDjlU= =qqir -----END PGP SIGNATURE----- >From in000566@students.univr.it Fri Sep 07 05:07:00 2001 From: Manganotto Filippo To: "Frank Ch.

If I have understood just, into file I would have to find the simulator memory into file, such as for example: : Is this right?
