Questions about these codes are asked so often on Usenet that we include
them here as a public service. This summary is excerpted from Werner
Almsberger's LILO User Documentation.
When LILO loads itself, it displays the word
LILO. Each letter is printed before or after performing
some specific action. If LILO fails at some point, the letters printed so
far can be used to identify the problem.
If the BIOS signals an error when LILO is trying to load a boot image, the
respective error code is displayed. These codes range from
0x00 through 0xbb. See the LILO User
Guide for an explanation of these.
