[ale] OT: osol CD won't boot

[hscast at charter.net (Scott Castaline)]

Okay maybe way off topic, but I'm not sure what's happening and I 
haven't been able to get an answer at OpenSolaris.org. I have been 
playing around with opensolaris 200811 on virtualbox. the image file as 
well as a cd burned with the image will boot in a VM. The problem I have 
is that when I try to boot on the actual physical machine I get know 
where, just a GRUB> prompt. When I manually step through the process, 
I'll get Error 25: Disk read error. I have just tried it on another 
system and it'll boot fine. The HCL has mention of a MoBo similar to 
mine as working, what else could be interfering with it?

TIA
