FATAL ERROR: no CD-ROM found
Press ENTER to reboot[/b]
It seems that it is looking for a CD-ROM device only?
I get the same message if I extract the ISO contents to the FAT32 USB flash drive.
you have to emulate the CD to get past this detection.
the zalman virtual image box emulates an usb mass storage device (usb CDROM) which
the the kernel enumerates during the boot process. this is something that most USB
gear does: like the 3G-sticks which have the "driver" diskette embedded, or some promotion
USB drives which are detected as a HDD *and* a CDrom.
generally booting iso from usb is easy, i did this several times with other "OS" (if you consider windows xp as an OS).
if you have grub or grub4dos you can create a memdisk, which holds the entire contents
of the iso file, promote it to be a drive, and boot off from it. but then it's just an int13h
device (hard disk).
you can however tweak linux kernel to look for iso-s and mount them while booting:http://www.syslinux.org/wiki/index.php/ ... the_kernel
it however requires this feature to be compiled in the kernel. but you can give it a try and
modify the kernel boot parameters in the 6.6 ISO file
