Studying for ICND and routerless...Have question

Probably the start to my downfall...I do have question around router memory. I am trying to figure out how you can calculate the total amount of flash memory, NVRAM, and ROM.

I used the router sim and typed the following command "show version" and it shows me various lines...How do identify how much memory for flash vs. NVRAM vs. ROM ?

I captured a snapshot from the cisco documentation:

Router_1#show version
ROM: System Bootstrap, Version 12.0, RELEASE SOFTWARE
BOOTFLASH: 3000 Bootstrap Software (IGS-BOOT-R), Version 11.0(10c)XB1,
RELEASE SOFTWARE (fc1)cisco WS-C3524-XL (PowerPC403) processor (revision 0x01) with 8192K/1024K bytes
of memory.
Router_1 uptime is 11 minutes
System restarted by power-on
System image file is c2500-js-1_120-8.bin, booted via flash

Bridging software.
X.25 software, Version 3.0.0.
1 Ethernet/IEEE 802.3 interface(s)
2 Serial network interface(s)
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read ONLY)


Any help would be much appreciated..

    To see how much flash memory you need to use the command show flash.


    If I remember correctly (its been a while) icon_wink.gif to see your total memory you have to combine two numbers together to get the total. I've bolded the numbers in red for reference.
    Router_1#show version

    So If you add 8192K + 1024K bytes that gives you the total NVRAM ??

    What is 32K bytes of non-volatile configuration memory represent ?

    Total RAM size = 8192K + 1024K
    8192K represents primary memory or processor memory (for storing running configuration and all routing tables).
    1024K represents shared memory or I/O memory (for buffering packets, all the interfaces share this memory).

    NVRAM size = 32K (for storing start-up configuration).

    Flash Memory size = 8192K (last line of the show version output).

    This helps me out....

    Does "show version" provide the ROM size or no ?
