L error

The first stage boot loader has been loaded and started, but it can't load the second stage boot loader. The two-digit error codes indicate the type of problem. (See also the LILO Disk Error Codes section, below.) This condition usually indicates a media failure or bad disk parameters in the IPCop PC's BIOS.
--------------------
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
