Linux Installation and Configuration Guide for AlphaServer 31

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

1024 Meg of system memory probing hose 1, PCI

bus 0, slot 7 -- ewa -- DE500-AA Network Controller bus 0, slot 8 -- pka -- QLogic ISP1020

probing hose 0, PCI

probing PCI-to-ISA bridge, bus 1

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
dka0.0.0.8.1	DKA0	RZ1DF-CB	0371
dkb500.5.0.8.0	DKB500	RRD46	1337
dva0.0.0.0.0	DVA0
ewa0.0.0.7.1	EWA0	00-00-F8-10-AE-C5
pka0.7.0.8.1	PKA0	SCSI Bus ID 7	5.57
pkb0.7.0.8.0	PKB0	SCSI Bus ID 7	5.57

In the output above, the first line shows that DKA0 is a hard disk, DKB500 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.

Boot the system using the "boot" command. The result should be that the system boots from the floppy. You will eventually be prompted to replace the BOOT floppy with the RAMDISK floppy.

If during this process you encounter a problem, such as due to a typographic error in the setting of the SRM parameters, you will probably be stopped with an "aboot>" prompt. The best way to deal with this situation is to reset the system using the reset button on the front panel. Then using the SRM commands, correct the mistake, and repeat the "boot" process.
