You can use it to dump physical memory, for example, od (mem)+2 dump first 1K of memory od --skip-bytes=0x413 --read-bytes=2 (mem) dump the word at 0x413.

In some case, it's not easy to access the boot media, such as, cdrom or pxe. To boot from such media, you can either put everything in core.img, or you can create a minimum core.img, and put other files, like *.mod, grub.cfg, font, etc, in an initrd. The initrd can be loaded along with core.img, using loader such as isolinux or pxelinux. -- Bean <[EMAIL PROTECTED]> _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
