Figure 4-15. Boot Loader Installation
Tip
If you have a RAID card, be aware that some BIOSes do not support booting from the RAID card. In
cases such as these, the boot loader should not be installed on the MBR of the RAID array. Rather,
the boot loader should be installed on the MBR of the same drive as the /boot/ partition was created.
If your system only uses Red Hat Enterprise Linux, you should choose the MBR.
Click the Change Drive Order button if you would like to rearrange the drive order or if your BIOS
does not return the correct drive order. Changing the drive order may be useful if you have multiple
SCSI adapters, or both SCSI and IDE adapters, and you want to boot from the SCSI device.
The Force LBA32 (not normally required) option allows you to exceed the 1024 cylinder limit for
the /boot/ partition. If you have a system which supports the LBA32 extension for booting operating
systems above the 1024 cylinder limit, and you want to place your /boot/ partition above cylinder
1024, you should select this option.
Tip
While partitioning your hard drive, keep in mind that the BIOS in some older systems cannot access
more than the first 1024 cylinders on a hard drive. If this is the case, leave enough room for the /boot
Linux partition on the first 1024 cylinders of your hard drive to boot Linux. The other Linux partitions
can be after cylinder 1024.
In parted, 1024 cylinders equals 528MB. For more information, refer to:
