In this section it all comes together. We will walk through an entire serial console upgrade, not that it differs much from a standard text mode upgrade.
Configure BIOS to boot from floppy or insert the floppy disk. Now reboot the machine.
bash# shutdown -r now

Because we have booted into expert mode, the menus differ slightly from the standard upgrade. For example, you probably don't have a driver disk.
Welcome to Red Hat Linux +----------+ Devices +-----------+ | | | Do you have a driver disk? | | | | +-----+ +----+ | | | Yes | |[No]| | | +-----+ +----+ | | | +--------------------------------+ |
The upgrade then continues in the usual fashion.
+--------+ Choose a Language +---------+ | | | What language should be used during | | the installation process? | | | | Czech : | | [ English : ] | | Danish : | | French : | | German : | | Hungarian : | | Icelandic : | | Italian : | | | | +----+ | | |[OK]| | | +----+ | | | +--------------------------------------+ |
Select HTTP to upgrade from the web server we prepared previously.

Here we supply the network details recorded in Example C-1. If your network supports Dynamic Host Configuration Protocol or the Bootstrap Protocol then these work fine too.
+--------------------+ Configure TCP/IP +--------------------+ | | | Please enter the IP configuration for this machine. Each | | item should be entered as an IP address in dotted-decimal | | notation (for example, 1.2.3.4). | | | | [ ] Use dynamic IP configuration (BOOTP/DHCP) | | | | IP address: 10.1.2.3________ | | Netmask: 255.255.255.0___ | | Default gateway (IP): 10.1.2.254______ | | Primary nameserver: 10.255.1.1______ | | | | +----+ +------+ | | |[OK]| | Back | | | +----+ +------+ | | | +------------------------------------------------------------+ |
Provide the name of the pre-prepared web server. Note that the response to Red Hat directory must start with a /.
+-----------------+ HTTP Setup +-----------------------------------+ | | | Please enter the following information: | | | | o the name or IP number of your web server | | o the directory on that server containing | | Red Hat Linux for your architecure | | | | Web site name: www.example.edu.au_______________________ | | Red Hat directory: /redhat/linux/7.1-20020202/en/os/i386____ | | | | +----+ +------+ | | |[OK]| | Back | | | +----+ +------+ | | | +------------------------------------------------------------------+ |
The following status messages then fly by before the welcome screen appears.

+----------------+ Red Hat Linux +-----------------+ | | | Welcome to Red Hat Linux! | | | | This installation process is outlined in detail | | in the Official Red Hat Linux Installation | | Guide available from Red Hat Software. If you | | have access to this manual, you should read the | | installation section before continuing. | | | | If you have purchased Official Red Hat Linux, | | be sure to register your purchase through our | | web site, http://www.redhat.com/. | | | | +----+ +------+ | | |[OK]| | Back | | | +----+ +------+ | | | +--------------------------------------------------+ |
Select Upgrade Existing Installation, although this procedure works fine for installations as well.
+--------------+ Installation Type +--------------+ | | | What type of system would you like to install? | | | | Workstation | | Server System | | Laptop | | Custom System | | [ Upgrade Existing Installation ] | | | | +----+ +------+ | | | OK | | Back | | | +----+ +------+ | | | +-------------------------------------------------+ |
The upgrade continues. When the LILO Configuration screen appears insert the kernel parameters recorded from Example C-2. These parameters should include console=ttyS….
+---------------------+ LILO Configuration +---------------------+ | | | A few systems will need to pass special options to the kernel | | at boot time for the system to function properly. If you need | | to pass boot options to the kernel, enter them now. If you | | don't need any or aren't sure, leave this blank. | | | | [ ] Use linear mode (needed for some SCSI drives) | | | | console=tty0 console=ttyS0,9600n8_______________ | | | | +----+ +------+ +------+ | | | OK | | Skip | | Back | | | +----+ +------+ +------+ | | | +----------------------------------------------------------------+ |

+----------------------+ LILO Configuration +-----------------------+ | | | The boot manager Red Hat uses can boot other operating systems | | as well.

The upgrade continues. As installing the packages may take a few hours, you can disconnect.
+-------------+ Package Installation +--------------+ | | | Name : | | Size : | | Summary: | | | | Packages Bytes Time | | Total : 0 0M | | Completed: 0 0M | | Remaining: 0 0M | | | | | +---------------------------------------------------+ |
If you disconnected, then when reconnecting it is best to press Tab rather than pressing Return.
Pressing Return on the Bootdisk screen writes a boot disk. This will overwrite the upgrade disk.
You may wish to deliberately create a boot disk if you cannot alter the BIOS parameters to boot from the hard disk, or if you cannot wait for someone to eject the floppy disk before rebooting.
+------------------+ Bootdisk +-------------------+ | | | A custom boot disk provides a way of booting | | into your Linux system without depending on | | the normal bootloader. This is useful if you | | don't want to install lilo on your system, | | another operating system removes lilo, or lilo | | doesn't work with your hardware configuration. | | A custom boot disk can also be used with the | | Red Hat rescue image, making it much easier to | | recover from severe system failures. | | | | Would you like to create a boot disk for your | | system? | | | | +-----+ +----+ | | |[Yes]| | No | | | +-----+ +----+ | | | +-------------------------------------------------+ |
When the Complete screen appears prepare to reboot into Linux. If you have a serial BIOS be prepared to alter the BIOS parameters to boot from the hard disk first. If you do not have a serial BIOS ask someone to eject the floppy disk.
+-----------------+ Complete +------------------+ | | | Congratulations, installation is complete. # | | : | | Press return to reboot, and be sure to : | | remove your boot medium after the system : | | reboots, or your system will rerun the : | | install. For information on fixes which : | | are available for this release of Red Hat : | | Linux, consult the Errata available from : | | http://www.redhat.com/errata. : | | : | | Information on configuring and using your : | | Red Hat Linux system is contained in the : | | | | +----+ | | |[OK]| | | +----+ | | | +-----------------------------------------------+ |
