Now we've talked about Solaris 11 booting to a small degree and really we've focused on X86 platforms. And as part of this installation process we're going to talk about accessing the Open Boot PROM or OBP. Now OBP has been around for a little while since Solaris 10 at last and what we have is this is usually used on a Spark platform. Now we're just going to touch the OBP a little bit we're going to talk about starting up and shutting down Solaris 11 both on X86 and Spark platforms a bit later. So this is just basically to tell you what the Open Boot Prom or OBP really is. Now the PROM which stands for Programmable Read-Only Memory, that's the system firmware. And we really look at Open Boot PROM on the Spark. Now Grub we've seen on the X86 platforms, you haven't seen that yet but you probably will before the course is over with, you'll be familiar with it. Right now we're going to talk about the OBP just a little bit, just to kind of familiarize you with it. Now the OBP basically is used to access the boot device on a Spark platform and transfer the boot archive to the system memory. Now this process is called Boot Strapping and you've probably heard of it before, even PCs use Boot Strapping, a little bit differently but they use Boot Strapping to load the executable software into memory that boots the computer. Now there's, there's a couple of different commands that you can use with the Open Boot PROM or OBP and again don't get wrapped around the axle with these just yet. We're going to talk about starting up and shutting down the system later on in the course. The Boot Command is one of those and you can use this with parameters, for example you can say Boot Net at the prompt and it will boot into a network type of boot. In other words it will go out and find a DHCP Server and boot possibly on a network image. There's some other commands that you can use as well. The EPROM Utility is used again on a Solaris box to set the PROM Parameters. It can set network parameters, network boot parameters, it can set the boot device itself and so forth. Monitor is another command that we use to access the PROM and we'll cover it a little bit later as well. And there's also other commands that we can use that really aren't part of EPROM or Monitor but they access the PROM in certain ways. For example Banner can tell you what version of the PROM you're running. In other words what version of firmware you're running and there's several other commands and things that you can use at the prompt to set boot devices, look at SCSI devices, get device IDs and things like that. And they all access the Boot PROM firmware, the Open Boot PROM. So we'll talk about these a little bit as we go through the course and you'll probably learn a lot more when we talk about starting the system up and shutting it down. That's a whole couple of sessions that we'll discuss this with. So this is an introduction to the Open Boot PROM and what it is and kind of what it does for you. And it really, we see this on a Solaris 11 box, this installed on our Spark platform, not so much on an X86 platform. And you'll find it as we go through the course most of the discussion will have probably is going to be X86 focused because that's really where the community is going, that's where most of these servers are being installed now. Spark's a great platform, it's really fast but it's not really compatible with a lot of other things. Really just Solaris 11 and Solaris 10 and a few other versions of Solaris. But it's really not compatible with any other operating system and the tendency is to go and buy something and install it that can run different things, that's more compatible. So the tendency is becoming to buy X86 systems and install a wide variety of things on them and Solaris 11 obviously is one of those things. So you'll see the course slightly slanted toward the X86 platform but we will discuss Spark issues and architectures as we go through it. So stay tuned and you'll get some more information Spark as we get through the course.
