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.
