Linux on your powermac
Select the installation medium from where you will install (viz. CD-ROM drive, first or second floppy drive, hard disk etc.) If you have the CD-ROM in the CD drive, select CD-ROM drive as source. Next option will enable you to configure the Device Driver modules. Here, you can load the modules provided by different vendors. If you have such modules, load, otherwise just skip this step.
You can select the modules, which are otherwise called loadable device drivers that are to be loaded with the kernel. Here you can select the modules from a lot of categories shown down in the menu. Select each category and enable the required things. One thing you have to keep in mind is that you should not try to install modules that are not present in the system because this could crash/hang the installation. When you go to a category, there will be a lot of modules that could be enabled. The modules that are currently installed on the system either have "+" character to the right of their name or "-". To install a module select the module and hit enter.
7 Configure the network
You should enable the corresponding modules of network card before doing this if the card is not recognized by the system. To check whether the card has been detected, use ALT + F2 to open another shell from where you issue the command
which will tell the status of the detection while booting. By default Power Macintosh 8500/120 comes with a 3Com 3c59x.c integrated Ethernet card, which will get detected. Now you have the card detected and you can give the host name for your Debian system. You have to choose the DHCP or BOOTP now. Choose NO if there is no DHCP or BOOTP. Give IP address, subnet mask and gateway IP address from your pool of IP addresses for the system. You can give the domain name in which you would like to add this machine into and the name server for that domain. This configuration is optional.
8 Install the base system
Select the medium from which you are going to install the Base System. You will have to wait for a while so that the requisite files are extracted and installed. Next option is to configure the Base System where you will select you Time Zone. I selected ASIA, Calcutta and did not set to GMT.
9 Make Linux boot from hard disk
