output of prtconf


Hi all,

I have questions about the output of prtconf command.

I issued the following command:

Code:
/>prtconf
System Configuration:  Sun Microsystems  i86pc
Memory size: 1024 Megabytes
System Peripherals (Software Nodes):

i86pc
    scsi_vhci, instance #0
    +boot (driver not attached)
        memory (driver not attached)
    aliases (driver not attached)
    chosen (driver not attached)
    i86pc-memory (driver not attached)
    i86pc-mmu (driver not attached)
    openprom (driver not attached)
    options, instance #0
    packages (driver not attached)
    delayed-writes (driver not attached)
    itu-props (driver not attached)
    isa, instance #0
        motherboard (driver not attached)
        asy, instance #0
        asy, instance #1
        lp, instance #0
        fdc, instance #0
            fd, instance #0
            fd, instance #1 (driver not attached)
        i8042, instance #0
            mouse, instance #0
            keyboard, instance #0
    pci, instance #0
        pci15ad,1976 (driver not attached)
        pci8086,7191, instance #0
        pci15ad,1976 (driver not attached)
        pci-ide, instance #0
            ide, instance #0
                cmdk, instance #0
                cmdk, instance #1 (driver not attached)
            ide, instance #1
                sd, instance #0
                st, instance #0 (driver not attached)
        pci15ad,1976 (driver not attached)
        display, instance #0
        pci1000,30, instance #0
        pci1022,2000, instance #0
    used-resources (driver not attached)
    pseudo, instance #0
    xsvc, instance #0
    objmgr, instance #0
    cpus (driver not attached)
        cpu, instance #0 (driver not attached)
My questions are:
1) I noticed some the output lines are saying "driver not attached" to some essential devices like cpu, i86pc-memory, and motherboard. How the system is working without drivers being laoded for those devices?
2) Where can I find information about the meaning of the command output? My target is to obtain information about the devices recognized by Solaris.

I tested the command on Solaris 10 installed on VMWare 5.5.
Code:
/>uname -a
SunOS sun1 5.10 Generic i86pc i386 i86pc
Thanks in advance.

Hopefully, a CPU, RAM or a motherboard do not require a device driver for them to be used. If they do, how would the O/S load it ?

prtconf output is targeted to Solaris kernel specialists who are already used to this terminology.
You can get information for most of the drivers by looking their manual page.
For your need, /usr/X11/bin/scanpci may be a better choice.
