Hi All...

I Recently installed RHELAS 3.0 ... with kernel 2.4.21-15.EL...
during installation i selected EVERYTHING option from custome part of installation....
I installed successfully... but during boot up....i got a message like...this redhat taroon update requires 256 MB RAM detected (114 MB).... normal boot up starts up....

1. I would like to know how to detect my RAM size through terminal...?
2. what is the difference between initial root file system and normal root file system..?

any help would be appreciate...

thnx in advance...

1. I would like to know how to detect my RAM size through terminal...?

The only two root filesystems i can think of are

/
and
/root

The first is the "root" of your entire filesystem, and the second being root's (the super user) home directory.

thnx Linux - powered for kind semi reply....

r u sure that MemTotal is for RAM size....?

i found that MemTotal : 117596 kB so far... with this info me guessing that me having 128 MB RAM.... ? if so its nice...means i need one more ram for my system..
thanq vey much... but could u have any idea about my second question... any help would be appreciate...?

thnx in advance..

didn't i answer it.....? Or is there something i do not know, because my first intuition was that you were confused about something, but correct me if I'm wrong. What do you mean by initial versus normal? Or is this wherein the confusion lies? Where do or did you read "initial" and "normal"?

Yes

I too am confused about your second question. Do you mean the difference between / and /root?

Hi student... thnx for nice reply...
plz understand my question...? when i am trying to bootup ..
i think inital root file system was started .. but because of insufficient RAM size (128 MB more required for mys system configuraion) it goes to Normal boot up (i think normal root file sytem was started but not sure)..that's why i found a message like "normal boot up" was started....? me totally confused here... is there anyhelp ... anyhelp would be appreciated....

thnx in advance..

Are these options you see on LILO/GRUB? Or after LILO/GRUB that you see somewhere scrolling on the screen?

You mean initial ram disk? It's a very small chunk of memory set aside used to run a program before the kernel is up and running, because the kernel isn't fully functional as it's still booting up, so it loads the small program into your ram while the OS is booting.

ah that could be what it is...

I wouldn't worry about it, personally... but if it really does bother you, give more description as to where and when you see the things happening that you are describing.

thnx linux-powered and student04... u done a gr8 job for me.. me going to study initrd manual.... now i got some idea about it....

thnx once again...
bye...

no problemo

Can someone help me with the difference between / and root??

Please don't hijack a thread. Start a new one.

However, in this case I'll try to clarify.

1. '/' is the root (sic) of the filesystem. IOW, all dir/file paths start with '/'. There is only one, no matter how many disks you have.
2. '/root' is the home dir of the root (admin) user. Other users home dirs are normally under /home eg /home/user1 etc.
