Installation Guide-IA64 In order to start the installation of Asianux 2.0, it needs to boot installation program. We can use two methods: CD booting or floppy booting. 1. Method of booting installation program According to the difference between hardware of system and installation medium that is used, we can use the following method to boot the installation program of Asianux 2.0. 1.1 Use CD booting CD booting and CD installing are the most direct method to install Asianux 2.0. The precondition of it is that the users have the system installation CD and the user decided to choose CD as the installation medium, and the computer can support the situation that booting from CDs. Set the BIOS startup order of current computer firstly when installing, set the CD-ROM as the first option. If your computer can not support CD booting, please refer to "Installation mode of Asianux" 1.2 Use U disk booting If the computer cannot support CD booting or you do not have a system installation CD, it needs to use installation boot CD. The reflection file of the installation boot CD is the file /images/bootdisk.img on the first CD. Before using the installation boot CD, you have to change the BIOS setting into U disk precedence. If an installation boot CD is needed, you should prepare in advance. Concerning the detailed information of making a boot CD, please refer to chapter 1.4: Making an installation boot CD These is no essential relationship between the mediums of booting and installing. Actually, using CD booting can also choose installation from hard disk or network. Detailed steps are as follows: After use the first CD of Asianux 2.0 to boot installation, input “linux askmethod” under the prompt “boot:”. It will appear a choice interface of installation medium. You can practice if you are interested in it. 1.3 Booting of EFI system EFI is the next general firmware of Intel, and Asianux 2.0 has already supplied the support for it. 1 1.3.1 Booting of EFI on IA32 Put the CD into CD-ROM, and restart the computer. Press <F2> to enter Boot manager if it appears “start boot options” at the bottom of the screen. Choose “cdrom entry1”, start the computer from CD. Or start computer from CD directly, and then input “linux efi” to enter installation mode supported by efi. A vfat partition of 100M is needed during installing; the mount point is /boot/efi. This partition must be a primary-partition; it is suggested to use hda1. Other processes are similar to other installation mode. 1.3.2 Booting of EFI on Itanium2 On Itanium2 server, computer will enter inner EFI （ Extensible Firmware Interface ） environment after self-inspecting, we need to select booting from CDROM/DVD in EFI. The full name of EFI is Extensible Firmware Interface; it is a technique that Intel used to substitute current BIOS. It is used to provide the function that is similar with BIOS for IA-64 constitution server system, and it is used to accommodate the functions of hardware. The work mode of EFI can be simply reduced to the following four: start up system, initialize standard firmware flat, load EFI drives library and carry out relative program. Select the system that you want to enter in the starting menu of EFI system and put in the code of start-booting to EFI. It will enter the system normally; otherwise it will pause starting up service and return the start menu of EFI. Start menu of EFI system Open the power of server; insert the first CD or booting CD into CDROM/DVD drive. The server will enter the inner EFI and start up manager after self-inspecting, select boot from CDROM/DVD in the starting manager menu of EFI. If there is no CDROM/DVD option, you can adopt the following two methods: 2 1. Select “EFI Shell [Built-in]”in menu, enter the inner EFI shell, you will find a drives list, the drives that start with fs are the drives of file system that can be discriminated by EFI. Find the one that corresponds to CDROM/DVD drive, enter this drive using the same method with switching drive under DOS (input the command that similar with fs0: and press <Enter>, then carry out the command elilo and start to boot CDROM/DVD). EFI Shell 2.Select “Boot option maintenance menu”in the menu，enter the menu of the next level. Boot option maintenance menu Select “Boot from a File”，then you can see a drives list, and select CDROM/DVD. 3 Boot From a File The files on CDROM/DVD will be listed out, select elilo.efi to boot CDROM/DVD. Select booting file 1.3.3 The use of efibootmgr z Delete guiding option # efibootmgr -b 0001 -B 0001 is the number of guiding option that is to be deleted, it can be examined thought the command efibootmgr directly, the output is as follows: # efibootmgr BootCurrent: 0001 Timeout: 10 seconds BootOrder: 0001,0002,0003 Boot0001* Asianux Boot0002* RedFlag Boot0003* Primary Master CDROM Among this, 0001 in Boot0001 is the number; the relevant guiding number is Asianux z Add a guiding option #efibootmgr -c -w -L "BootOptionName" -d /dev/sda -p 1 -l \\EFI\\asianux\\elilo.efi 4 Among this, it is the name of the hardware that the system belongs to after the parameter –d, for example, /dev/hda、 /dev/hdb The parameter –p is the partition number of vfat partition, /dev/hda1 uses -p 1, and /dev/sda2 uses -p 2. The parameter –l is followed by the location of the efi startup file in the partition that the guiding option points to. Please use “\\”to express the class of content. For example, /EFI/asianux/elilo.efi should be written into \\EFI\\asianux\\elilo.efi. 1.4 Boot successfully Whatever is used (CDs or floppy), it will appear an installation startup interface of Asianux 2.0 after booting successfully. The hints and the prompt “boot:” will appear on the screen，then you can enter the graphics-mode installation interface after pressing <enter> or just waiting for a while. Boot from CD successfully If it need to use text installation mode, input “linux text” under the prompt “boot:”, then press <enter>. If it need to use expert installation mode, input “linux expert” under the prompt “boot:”, then press <enter>. It is suggested to use graphics-mode installation mode; because it has friendly interface and can be operated easily. And it also supplies the LVM setting function that can not be supplied under text installation mode. In normal situation, it just need to use acquiescent options. Pay attention to the leading message to check that if the 5 Linux kernel has examined the hardware of computer. If the hardware has been examined correctly, we can carry the following procedure of installing. ¾ Concerning text installation mode The operating steps of text installation mode are similar with graphics-mode installation, it just changes its interface, and the setting and using method are also similar. If the text installation mode is necessary, please refer to the next chapter about the introduction of graphics-mode installation. Currently, hard-disk installation mode, FTP installation mode and HTTP installation mode just supply text installation interface. ¾ Concerning expert installation mode Expert installation mode adopt text interface to supply drive support that some installation program do not supply for some special hardware. Currently, these special hardware are mostly SCSI adapters, RAID equipment or NIC. Asianux 2.0 installation program has already supplied hundreds of drives of this kind of equipment for users. But to the types that do not include, it needs to use drive floppy or drive CDs to load drives thought expert installation mode. In expert installation mode, installation program will ask users whether a drive disk is needed. Then select to load drive program from floppy drive or CD drive. If you do not need equipment that is not supported during your installing of Asianux 2.0, the drive disk does need here. You can add the support of this equipment after completing installation. Asianux 2.0 has its own format of drive floppy, if it can not match the format, it may lead to load incorrectly. 2. Installation of Asianux 2.0 It is written above that installation program can use text interface installation mode as well as graphic installation mode. This chapter will introduce the detailed steps of installation of Asianux 2.0 by taken examples of graphic installation mode. We consumingly advise you to use graphic installation mode to carry out the installation; because it has friendly interface and can be operated easily, and it also include the LVM configuring function that cannot be supplied under text installation mode. If the text installation mode is n necessary, you can also get necessary information from the explanation of graphic installation mode in this chapter. 6 2.1 Starting installation Complete the booting of installation program, and enter the graphic installation interface as the following picture shows. Starting installation Red Flag Server supply uniform graphic installation interface style, the left side of the screen list all the steps that will pass during the entire installation and shows the current step; the right shows the configuring options of relevant installation steps and the parameter configuring interface. At the bottom of the screen, there has three buttons: “Exist” means you can exit the installation program at any time, and restart the computer; “Back” means you can return to the above interface; “Next” means that the current option is affirmed and it will enter the next installation step.
