. .Ss2 Deciding on partition sizes . If you're installing .Nx*M for the first time it's a good idea to look at the partition sizes of the disk you plan to install .Nx on. Will you be installing .Nx onto the same disk as .Tn Solaris , or on its own disk (or netboot)? While .Nx can work just fine on a disk shared with .Tn Solaris , the .Nx installer does not currently support this.
p Assuming a classic partition scheme with
a / (root) and
a /usr file systems, a comfortable size for the .Nx
a / partition is about 64 MB; a good initial size for the swap partition is twice the amount of physical memory in your machine (though, unlike .Tn SunOS 4.x, there are no restrictions on the size of the swap partition that would render part of your memory unusable). A full binary installation including X11R6 takes nearly 200 MB in
a /usr . . .Ss2 Setting up Open Firmware . First, you need to stop your system from automatically booting when powered on. Pressing the .Key STOP key (sometimes called the .Key L1 key, found on the left side of your keyboard) and the .Key a key will halt your system and give you the .Dq Li ok prompt. If you are using a serial console, send a .Dq BREAK signal from your terminal (the method of sending .Dq BREAK varies from terminal to terminal).
p If the ethernet address of your \*M system is .Li ff:ff:ff:ff:ff:ff , then your NVRAM battery is dead and you will have trouble using ethernet (among other problems). Read the Sun NVRAM/Hostid FAQ. .Lk http://www.squirrel.com/squirrel/sun-nvram-hostid.faq.html
p If you have a valid ethernet address and you plan to netboot, write down your system's ethernet address.
p You cannot use the security modes of the SPARC OpenBoot PROM. .(disp .No ok Ic "setenv security-mode none" .disp)
p SCSI devices are specified by an Open Firmware c devalias which provides simple mnemonics for the full path to the device. Type c devalias to get a list of all of the available aliases. At a minimum, the alias and partition are necessary when booting.
p Therefore, to boot from the swap partition on the internal hard drive one would use:
p .(disp .No ok Ic "boot disk:b" .disp)
p To boot from a CD-ROM (Open Firmware assumes SCSI CD-ROMs are at target 6), one would use:
p .(disp .No ok Ic "boot cdrom" .disp)
p And, to boot from a kernel named .Li netbsd-GENERIC on the fourth partition ( .Sq Li d , often the
a /usr partition) on an external SCSI hard drive (target 2, partition 3), one would use:
p .(disp .No ok Ic "boot disk2:d netbsd-GENERIC" .disp)
p . .Ss2 Determining how to boot from an SBUS or PCI card . Some SBUS and PCI cards have firmware that lets you use them as a boot device. These cards do not automatically create a c devalias entry, so you must traverse the device tree to figure out what Open Firmware calls your card. You will be using Open Firmware commands at the .Sq Li ok prompt. First `cd' to the top of the device tree and list the nodes there. The following is the procedure to boot from an IDE card in an UltraSPARC 30. .(disp .No ok Ic "cd /" .No ok Ic "ls" f006cf08 SUNW,ffb@1e,0 f006c32c SUNW,UltraSPARC-II@0,0 f006002c counter-timer@1f,1c00 f005f410 pci@1f,2000 f005eb54 pci@1f,4000 f004cf84 virtual-memory f004c9a4 memory@0,0 f002ce38 aliases f002cdc8 options f002cc90 openprom f002cc24 chosen f002cbb4 packages .disp) Usually, you can simply type in the name before the at (@) sign and the OpenBoot PROM will fill in the rest. .(disp .No ok Ic "cd pci@1f,4000" .No ok Ic "ls" f0081524 ide@2 f007be50 scsi@3 f0074688 network@1,1 f0060324 ebus@1 .No ok Ic "cd ide@2" .No ok Ic "ls" 0081fe4 cdrom f0081938 disk .No ok Ic "cd disk" .No ok Ic "ls" .No ok Ic "pwd" /pci@1f,4000/ide@2/disk .disp) OK, now we know the path to the IDE device in this example. Now, we need to determine if it's capable of booting. If it is, it will have the c word `open'. .(disp .No ok Ic "words" close load write read seek open write-blocks read-blocks max-transfer block-size dma-free dma-alloc spin-down spin-up .disp) Great! Also, in case you're interested in further details about your hardware, you can use the `.properties' command.
p So, when it's time to type in a boot command, use the shortened version of the c pwd command. You need to be more specific if there are two devices with the same name (in this case, two /pci entries). In this example, you'd type: .(disp .No ok Ic "boot /pci@1f,4000/ide/disk@0,0" .disp) You can also store this device path across reboots using the c nvalias command. .(disp .No ok Ic "nvalias wd0 /pci@1f,4000/ide/disk@0,0:a" .disp)
p And when the kernel is done booting, it may not automatically use your card as the root device -- you may need to type in the .Nx*M name for that device: .(disp root on sd0a dumps on sd0b no file system for sd0 (dev 0x700) cannot mount root, error = 79 .No "root device (default sd0a):" Ic "?" use one of: hme0 sd0[a-h] wd0[a-h] halt .No "root device (default sd0a):" Ic "wd0a" .No "dump device:" Ic "wd0a" .No "file system (default generic):" Ic "ffs" root on wd0a .disp) . .Ss2 Configuration of network interfaces . Some network devices (i.e. certain SBus cards) allow a choice between operating on a UTP or a AUI port. The .Li le driver supports automatic detection of the port which is actually connected to the wire. If automatic detection is not available or not working properly in your environment, you may have to specify the type connection using the .Ar media parameter of .Xr ifconfig 8 . During installation, you'll get the opportunity to specify the appropriate medium. Use .Li 10base5/AUI to select the AUI connector, or .Li 10baseT/UTP to select the UTP connector.
