I got the solution. The command `grub-mkrescue' create an ISO image, it can not be taken as floppy. Otherwise grub shell command `configfile (fd0)/.../i386-pc/grub.cfg' will report "out of disk" error.
Taking the image as CDROM image will boot up the vmplayer. John _______________________________________________ Help-grub mailing list Help-grub@gnu.org http://lists.gnu.org/mailman/listinfo/help-grub
