3.14.2. Alternative Boot Loaders
If you do not wish to use GRUB or LILO to boot your Red Hat Enterprise Linux WS system, you
have several alternatives:
Boot disk
You can use the boot disk created by the installation program (if you elected to create one).
LOADLIN
You can load Linux from MS-DOS. Unfortunately, it 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 Enterprise Linux WS system using some
other method (for example, from LILO on a 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.
Some 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).
3.14.3. SMP Motherboards, GRUB, and LILO
This section is specific to SMP motherboards only. If the installation program detects an SMP moth-
erboard on your system, it will create two

3.15. GRUB Password
If you did not select GRUB as your boot loader, or did not install a boot loader, skip to Section 3.16.
GRUB passwords provide a security mechanism in an environment where physical access to your
server is available.
