12 ERR_DEV_VALUES Invalid device requested
13 ERR_EXEC_FORMAT Invalid or unsupported executable format (not bootable) - the ISO(?) you are trying to boot from is not bootable - maybe it is an Update CD instead of an Install CD\DVD? Maybe BIOS has the 128GB USB drive limit bug and file is too far on drive?

25 ERR_READ Disk read error
26 ERR_SYMLINK_LOOP Too many symbolic links
27 ERR_UNRECOGNIZED Unrecognized command

38 ERR_DISABLE_A20 Failed to turn off Gate A20!
39 ERR_DOS_BACKUP GRUB was not booted from DOS or the backup copy of DOS at physical address 0x200000 is corrupt
40 ERR_ENABLE_A20 Failed to turn on Gate A20!
41 ERR_EXTENDED_PARTITION Extended partition table is invalid or its CHS values conflict with the BPB in a logical partition
42 ERR_FILENAME_FORMAT The leading DEVICE of the filename to find must be stripped off and DIR for set-root must begin in a slash(/).

56 ERR_INVALID_RAM_DRIVE Invalid ram_drive. Should be between 0 and 254
57 ERR_IN_SITU_FLOPPY Only hard drives could be mapped in situ.
58 ERR_IN_SITU_MEM Should not use --mem together with --in-situ.

61 ERR_MANY_FRAGMENTS Too many fragments
62 ERR_NO_DRIVE_MAPPED Refuse to hook int13 because of empty drive map table
63 ERR_NO_HEADS The number of heads must be specified. The `--heads0' option tells map to choose a value (but maybe unsuitable) for you
64 ERR_NO_SECTORS The number of sectors per track must be specified. The `--sectors-per-track0' option tells map to choose a value (but maybe unsuitable) for you
65 ERR_PARTITION_TABLE_FULL Cannot use --in-situ because the partition table is full (i.e. all the 4 entries are in use).
