- Caution: All of the LILO components are installed in the proper

- default directories ONLY if you use "make install".

- Problem: LILO won't 'make'
- ==========================
- If you get errors trying to 'make all', and the errors are occurring
- during the assembly of 'temp2.s', you have encountered the most common
- problem trying to build LILO: the lines in error all have the assembler
- directive 'near' on them. This problem occurs when your assembler for
- the real-mode bootstrap code is out-of-date: 'as86'. Certain current
- distributions of Linux distribute version 4 of this assembler; whereas
- the current version is 15.
-
- Two sources for an updated version are:
-
- Redhat RPM distribution:
- site: http://www.redhat.com (search for 'dev86')
- pkg: dev86-0.15.0-2.i386.rpm
-
- or Robert de Bath's page at:
- site: http://www.cix.co.uk/~mayday
- link: bin86-0.15.1.tar.gz

- Problem: When I boot, all I get is 'LI'
- =======================================
- This means the first-stage loader gained control; it thought it success-
- fully loaded the second-stage loader; but it never got there. This most
- often occurs when the second-stage loader, '/boot/boot.b', is not load-
- able using the BIOS.
-
- First, have you tried specifying 'lba32' in your 'lilo.conf' file? On
- newer systems, this will almost always work, since the loader will now
- use the newer EDD packet calls, which are not cylinder-limited.
-
- Second, do you know your disk geometry? This means, do you know the
- numbers of cylinders/heads/sectors of all your hard drives; and are these
- the numbers that LILO is using when it installs the boot loader. Three
- reports of the disk geometry may be obtained:
-
- 1. Run 'lilo -t -v5' and check the geometry reports for each device.
- 2. Run 'lilo -Tgeom' and see if the same numbers are reported. (This
- may fail on some systems, where LILO has trouble running BIOS
- calls in v86 mode.)
- 3. Create the diagnostic floppy (see README.disk) and check the
- reported disk geometries.
-
- If any of the geometry reports differ, then you may have to specify the
- disk geometry to LILO using 'disk= heads= sectors='. Use the actual
- numbers reported by the BIOS: #3 above, or #2.
-
- The reports above will also indicate the BIOS device codes used by each
- disk. LILO uses heuristics to obtain these device codes, and usually gets
- the codes right on all-IDE or all-SCSI systems. However, systems with
- multiple IDE controllers, mixed IDE/SCSI systems, and SCSI systems on
- Future Domain controllers, will require you to tell LILO what disks are
- assigned to what device codes. This can be done using 'disk= bios=' lines
- in 'lilo.conf'.
