Lilo User Guide (II) Hubertzou@linuxaid.com.cn Iv. Analysis on startup error display of lilo <1> when lilo loads itself, the word "lilo" is displayed. Each time a specific process is completed, a letter is displayed. If lilo fails somewhere, there are several letters on the screen to indicate where the error occurred. More detailed descriptions are provided in the technical documentation. (Note: lilo is not a program, but a group of programs.) Note that if the disk fails instantly, some hexadecimal numbers may be inserted after the first letter "L. Unless lilo stops there and keeps generating error code streams, it does not indicate a serious problem. <2> (<nothing displayed after startup>) lilo is not loaded at all. Lilo may not be installed, or the partition is not activated. <3> L <error code>... the first part of lilo has been loaded and run, but it cannot mount the second part of the boot program. two-digit error codes indicate the type of the problem (see "disk error codes "). In this case, media access fails or the hard disk geometric parameters (CHS, CHS) do not match. The second part of lilo has been mounted in the first phase of Li Lilo, but it fails to be executed because the hard disk geometric parameters do not match or After/boot. B is moved, the ing (MAP) Installer is not re-run. The second stage of LIL has been started, but it cannot read the descriptor table from the map file. The typical reason is that the media An error occurs or the hard disk geometric parameters do not match. LIL? The second part of LILO is mounted to the wrong address. The typical cause is that the hardware geometric parameters are not matched or/boot. B is Move without running the ing installer. The LIL-Descriptor Table is corrupted. This may be because the/boot/map does not run the ing installer or the geometric parameters do not match after it is moved. All parts of LILO are successfully loaded. 1010101010 the partition status has changed, but LILO has not been re-installed. It is said that the overclocking will also happen. Disk error code: 0x00 "internal error ". It is generated by the reading subroutine of The LILO sector. It may be because of the corrupted file. try rebuilding the map file. Another original This may be because when the linear parameter is used, more than 1024 of the cylinder is accessed. 0x01 "invalid command ". It shouldn't happen. If it appears, it means LILO can access hard disks not supported by BIOS. When sorting this document A friend of mine encountered the L010101. .. error because he installed Linux on the second IDE port (/dev/hdc) and added the Disk parameter. 0x02 "no address Mark found ". It is usually a medium problem. Try again several times. 0x03 "Write protection error ". It only appears during write operations. 0x04 "sector not found ". The typical cause is that the hard disk parameters do not match. 0x06 "activation sequence change ". This should be a short error. Try again. 0x07 "invalid initialization ". The BIOS does not properly initialize the hard disk. A hot boot may be helpful. 0x08 "DMA exceeds the limit ". This should not happen. Restart. 0x09 "DMA attempts to cross 64 K boundary ". This should not happen. We recommend that you ignore the COMPACT parameter. 0x0C "invalid media ". This should not happen. Restart and check. 0x10 "CRC error ". Media error detected. We recommend that you run the map installer several times and write the map file from Bad blocks to normal Quality. 0x11 "ECC corrected successfully ". The read error occurs and is corrected, but LILO does not know the situation and terminates the startup process. 0x20 "Controller error ". It should not happen. Ox40 "locating failed ". This may be a media issue. Restart and try again. 0x80 "disk timeout ". The disk or drive is not ready. The media is broken or the disk is not switched. If the disk is started from a floppy disk, it may not be closed. 0xBB "BIOS error ". This should not happen. If this happens repeatedly, consider removing the COMPACT parameter or adding/canceling the LINEAR parameter. If an error occurs during the write operation, the error code is prefixed with "w ". Although write errors do not affect the startup process, they indicate some errors because they indicate errors in the system. A good suggestion is to reconfigure LILO to read-only ). 5. Forgot the password? After the system is started, you will see a console-based logon screen or xdm-based logon screen. Log On As root and use the password you set during installation. If you forget this password, You can use the single or emergency boot option. In lilo boot: Enter linux single at the prompt to boot to enter single-user mode. In single-user mode, your local file system will be installed and the network service will not be activated. In the emergency transaction mode, the system does almost no setup, only the root file system is installed, and it is read-only. After entering the single-user mode, you can use passwd to change the root password. 6. How do I enable the system urgently if lilo is damaged or cannot be started? You can use a CD or install a floppy disk to start the instance. After the boot prompt is displayed, type: Vmlinuz root =/dev/linuxrootpartition noinitrd Enter the Partition Number of your Linux Root partition after "root =", for example: Vmlinuz root =/dev/hda3 noinitrd Press enter to enter your Linux system. You can edit/etc/Lilo. conf and run/sbin/Lilo.
