[coreboot] filo booting cd problem

[joe at smittys.pointclark.net]

Hello,
I am trying to boot the GeeXboX installer cd from the filo grub prompt  
and I keep getting this
message:
hdc: ATAPI: SONY    DVD RW DRU-710A
8MB medium detected
Disc doesn't use boot disk emulation

What am I doing wrong?

Thanks - Joe
