Appendix A. Upgrading Your Current System

Figure A 5. Boot Loader Installation

If your system will use only Red Hat Linux, you should choose the MBR. For systems with Windows

95/98, you should also install the boot loader to the MBR so that it can boot both operating systems.

Click the Change Drive Order button if you would like to rearrange the drive order. Changing the

drive order may be useful if you have multiple SCSI adapters or both SCSI and IDE adapters and 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.

If you wish to add default options to the boot command, enter them into the Kernel parameters field.

Any options you enter will be passed to the Linux kernel every time it boots.

A.5.3. Rescue Mode

If you need to use rescue mode, there are several options available to you.

Using the CD ROM to boot, type linux rescue at the

boot:

prompt.

By booting your system from an installation boot diskette made from the

boot.img

image. This

method requires that the Red Hat Linux CD ROM #1 be inserted as the rescue image or that the

rescue image be on the hard drive as an ISO image. Once you have booted using this diskette, type

linux rescue at the

boot:

prompt.

By booting from a network diskette made from the

bootnet.img

or PCMCIA boot diskette made

from

pcmcia.img

. Once you have booted using this diskette, type linux rescue at the

boot:

prompt. You can only do this if your network connection is working. You will need to identify the

network host and transfer type. For an explanation of how to specify this information, see Section

3.7.

For more information, refer to the Official Red Hat Linux Customization Guide.
