No. both grub and lilo work through the system BIOS. Neither can |
13 |
'see' things not provided through the system BIOS. |

But grub and lilo do work very differently in their 'normal' |
16 |
configurations. Lilo records absolute disk blocks where the kernel is |
17 |
located, and loads the kernel directly from those blocks. This is why |
18 |
you have to re-run lilo every time you update your kernel. |

Grub however has some knowledge of filesystems, so can actually read |
21 |
the filesystem that contains the kernel to determine what blocks to |
22 |
load. So it is possible (not so much today, but in years past) to use |
23 |
a filesystem that linux understands but grub does not. |
