I'm able to reproduce this kind of behaviour on an ASUS M2N-SLI mainboard when trying to boot from an external USB DVD writer device. In my case the Solaris GRUB optical boot media is readable just fine; It's the BIOS that starts reporting read errors for reads from the USB optical device, at the point when the /boot/grub/menu.lst file should be read. With a few hacks added to the GRUB boot code I'm able to work around that BIOS bug... This message posted from opensolaris.org
