[Fwd: Re: DiskOnChip Questions]

[Michael Robinson]

David,

LinuxBIOS has its own kernel correct?  Or is LinuxBIOS not really a 
Linux kernel, but boots a Linux kernel that can be stored on the 
DiskOnChip or HDD?  I just want to verify how it works because I've 
heard so many references to multiple kernels that I'm not sure exactly 
how the whole process works.  In response to your last question I'd like 
to boot my distro off of hard disk if I'm thinking correctly.

Thanks,
Michael Robinson
