Hi KrazyGuyPaul,

The problem, I think, is with the Linux Loader (LILO).

Until Red Hat 7.1, LILO was the only one boot loader available, but since Red Hat 7.2 you have the Grub Loader, that doesn't have this problem.

If I'm not make confusing, it seems that this problem is already corrected and the newest versions of LILO doesn't have this problem.

Take a look:

Booting with LILO

The usual and recommended method to boot into Linux is using LILO (the LInux LOader). LILO can install itself in your boot sector and allows you to choose which operating system you would like at boot time. Due to a technical limitation, LILO is unable to read data from the hard drive past the 1024th cylinder--the 8GB mark for modern LBA (Logical Block Addressing) hard drives.

Does this mean you can't use the rest of your drive? Not at all. What it does mean is that your boot partitions must all live below the 8GB mark, that is, below cylinder 1024. Thus, if you want Windows to use the first 9GB of your fancy new 18GB drive, you won't be able to use LILO to boot Linux. Because of this limitation, Red Hat's Disk Druid tool for partitioning the hard drive will not allow you to create your Linux boot partition past cylinder 1024. You can still create the partitions using fdisk, but Red Hat setup will not install LILO if you do.

RHN_CHECK(8)							  Red Hat Network						      RHN_CHECK(8)

NAME
rhn_check - check for queued actions on RHN and execute them SYNOPSIS
/usr/sbin/rhn_check [-v] [--verbose] DESCRIPTION
rhn_check is a client program that connects to the Red Hat Network backend servers and retrieves information associated with the queued actions for this particular system. This script reads the digital server ID from /etc/sysconfig/rhn/systemid and uses that to identify the machine to the Red Hat Network. Upon successfull authentication, rhn_check will start processing the queued actions sequentially. ACTION TYPES
The following types of actions are currently processed by rhn_check: action type description () () refresh This action will refresh the hardware or software profiles of this machine with Red Hat Network. This fucntion is called as refresh(hardware) or refresh(rpmlist) new_systemid This action is used by the RHn Backend to update the Digital system ID of this machine with a new one. update_packages This action will trigger rhn_check into running a package update for a list of packages queued from the Red Hat Network. rhn_check will use modules from the up2date client to download the packages, solve dependencies and install the on the system. FILES
/etc/sysconfig/rhn/systemid The digital server ID for this machine if the system has been registered onto Red Hat Network. This file does not exist otherwise. /var/spool/up2date This directory is used by up2date to store package headers and RPM packages downloaded from Red Hat Network SEE ALSO
man pages for up2date(8) and rhnsd(8). AUTHORS
