BOOT ERRORS
 The boot process takes place in two stages. The first
 stage loader is a single sector, and is loaded by the BIOS
 or by the loader in the MBR. It loads the multi-sector
 second stage loader, but is very space limited. When the
 first stage loader gets control, it types the letter "L";
 when it is ready to transfer control to the second stage
 loader it types the letter "I". If any error occurs, like
 a disk read error, it will put out a hexadecimil error
 code, and then it will re-try the operation. All hex
 error codes are BIOS return values, except for the lilo-
 generated 40, 99 and 9A. A partial list of error codes
 follows:

 00 no error
 01 invalid disk command
 0A bad sector flag
 0B bad track flag
 20 controller failure
 40 seek failure (BIOS)
 40 cylinder>1023 (LILO)
 99 invalid second stage index sector (LILO)
 9A no second stage loader signature (LILO)
 AA drive not ready
 FF sense operation failed

 Error code 40 is generated by the BIOS, or by LILO during
 the conversion of a linear (24-bit) disk address to a geo-
 metric (C:H:S) address. On older systems which do not
 support lba32 (32-bit) addressing, this error may also be
 generated. Errors 99 and 9A usually mean the map file (-m
 or map=) is not readable, likely because LILO was not re-
 run after some system change, or there is a geometry mis-
 match between what LILO used (lilo -v3 to display) and
 what is actually being used by the BIOS (one of the lilo
 diagnostic disks, available in the source distribution,
 may be needed to diagnose this problem).

 When the second stage loader has received control from the
 first stage, it prints the letter "L", and when it has
 initialized itself, including verifying the "Descriptor
 Table" - the list of kernels/others to boot - it will
 print the letter "O", to form the full word "LILO", in
 uppercase.

 All second stage loader error messages are English text,
 and try to pinpoint, more or less successfully, the point
 of failure.
