I have a similar problem with booting the live CD from my new desktop PC. It is an ASROCK N68PV-GS, GeForce 7050 AM2+ Mobo, 4 GB RAM, LG SATA II DL DVD RW, 320GB WD SATA II HDD, AMD Athlon 64 x2 5200+ 2.7GHz
Initially it would boot the Live CD and recently it has stopped working. It will boot to GRUB screen and then the dots start to appear and the machine hangs when it displays the blurb about 'SUN OS' etc. I tried to change the BIOS settings to no avail and then I realised the only thing to change in my setup is that I have recently added an internally fitted generic multiformat card reader which connects to one of the USB headers on the mobo. Unplugging the connecting cable allows the Live CD to boot without problems. Strange that this should happen as Ubuntu and Debian both boot from GRUB without problems and Fedora 11 hangs on boot like Opensolaris - Maybe they both share the same sort of setup on the Live CD? -- This message posted from opensolaris.org
