• Using the boot disk you have created, type linux rescue at the boot: prompt. You then
pick an installation method and choose a valid installation tree to load from.
For more information regarding rescue mode, refer to the Official Red Hat Linux Customization Guide.
3.14.2 Alternative Boot Loaders
If you do not wish to use GRUB or LILO to boot your Red Hat Enterprise Linux AS 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 AS 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
Partition 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 mother-
board on your system, it will create two /boot/grub/grub.conf or /etc/lilo.conf entries
(depending on the boot loader you installed), rather than the usual single entry.
The two entries in grub.conf will be Red Hat Linux ( kernel version ) and Red Hat
Linux ( kernel versions -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.
