So in my case FILO is booting the actual Linux kernel that you will be
using when you perform tasks on the computer? So if you were using a
DiskOnChip your Linux distribution kernel would be on the actual
DiskOnChip? I was under the impression that the LinuxBIOS kernel was on
the DiskOnChip and the distribution kernel was on a hard drive. Could
you please clarify.
Thanks,
