Appendix A. Upgrading Your Current System 83
A.5.4. Alternative Boot Loaders
If you do not wish to use a boot loader, you have several alternatives:
Boot diskette
You can use the boot diskette created by the installation program (if you create one).
LOADLIN
You can load Linux from MS-DOS. Unfortunately, this requires a copy of the Linux kernel (and
an initial RAM disk, if you have a SCSI adapter) to be available on an MS-DOS partition. The
only way to accomplish this is to boot your Red Hat Linux system using some other method (for
example, from a boot diskette) and then copy the kernel to an MS-DOS partition. LOADLIN is
available from
ftp://metalab.unc.edu/pub/Linux/system/boot/dualboot/
and associated mirror sites.
SYSLINUX
SYSLINUX is an MS-DOS program very similar to LOADLIN. It is also available from
ftp://metalab.unc.edu/pub/Linux/system/boot/loaders/
and associated mirror sites.
Commercial boot loaders
You can load Linux using commercial boot loaders. For example, System Commander and Parti-
tion Magic are able to boot Linux (but still require GRUB or LILO to be installed in your Linux
root partition).
Note
Boot loaders such as LOADLIN and System Commander are considered to be third-party boot load-
ers and are not supported by Red Hat.
A.5.5. SMP Motherboards, GRUB, and LILO
This section is specific to SMP motherboards only. SMP, short for Symmetric Multiprocessing, is a
computer architecture providing fast performance by making multiple CPUs available to complete
individual processes simultaneously (multiprocessing).
If the installation program detects an SMP motherboard on your system, it will automatically create
two boot loader entries (depending on the boot loader you installed), rather than the usual single entry.
Note
Intel® Pentium® 4 systems with hyperthreading will have an SMP kernel installed by default.
The two GRUB entries will be Red Hat Linux (kernel version) and Red Hat Linux
(kernel version-smp). The Red Hat Linux (kernel version-smp) will boot by default.
However, if you have trouble with the SMP kernel, you can elect to boot the Red Hat Linux
(kernel version) entry instead. You will retain all the functionality as before, but you will only
be operating with a single processor.
