Linux Installation and Configuration Guide for AlphaServer  44

There are several pieces of information that you need to configure in the SRM subsystem, as well 
as device identifiers that you should make note of, prior to beginning the installation process. The 
steps that follow take you through that process. 

Power up your system. After several diagnostics are completed, you will be presented an SRM 
prompt "P00>>>", as shown here: 

256 Meg of system memory

P00>>> 

Determine what devices your system has installed. In particular you will need to note your 
installation device (a floppy and/or CD-ROM), and your target disk drive. Entering the command 
"show devices" as shown below will print out the information about your system: 

P00>>>show device 
dka0.0.0.6.0               DKA0              COMPAQ BA03611C9B  3B05 
dka100.1.0.6.0             DKA100            COMPAQ BB01811C9C  3B05 
dka200.2.0.6.0             DKA200            COMPAQ BB01811C9C  3B05 
dqa0.0.0.105.0             DQA0                        CD-224E  9.5B     
dva0.0.0.0.0               DVA0                                
ewa0.0.0.9.1               EWA0              00-00-F8-01-F5-DA 
pka0.7.0.6.0               PKA0                  SCSI Bus ID 7 
pkb0.7.0.106.0             PKB0                  SCSI Bus ID 7 

In the output above, the first line shows that DKA0 is a hard disk, DQA0 is a CD-ROM, and 
DVA0 is a floppy drive. 

Also useful for inspecting the computer configuration is the "show config" command, as shown 
here: 

P00>>>show config | more 

Configure the system SRM parameters to boot from your installation device. The commands for 
configuring to boot from the floppy device are shown here: 

P00>>>set bootdef_dev dva0 
P00>>>set boot_file vmlinux.gz 
P00>>>set boot_osflags "root=/dev/fd0 load_ramdisk=1" 
P00>>>show boot* 
boot_dev             dva0.0.0.0.0     
boot_file            vmlinux.gz       
boot_osflags         root=/dev/fd0 load_ramdisk=1 
boot_reset           OFF              
bootdef_dev          dva0.0.0.0.0     
booted_dev                            
booted_file                           
booted_osflags

                        

 

Insert the boot floppy into the drive.
