Linux mem help

[Steven Chen_1]

I hope hp guru can help with Linux problem too:

I have a Linux box with 256M memory, but 'top' shows only 64M used. hp can use sam to adjust mem utilization, how about Linux?

The followings are the top page of Linux:

---------------
Mem: 64020K av, 52836K used, 11184K free, 24472K shrd, 31772K buff
Swap: 80284K av, 0K used,
80284K free 6356K cached
----------------

Thanks a lot,

Steven

You must change some kernel parameters.
in the case of linux I don't know wiches.

See some help about kernel for linux.

Ok.

You probably have an old kernel.
You must specify your available memory to the linux kernel because your bios only reports 64Mb to linux and it won't use more than that until you specify more.

To do it at your LILO boot prompt try :
linux mem=256M
It will pass the parameter mem=256M to the kernel before it loads...

If it works, edit your /etc/lilo.conf and add the line : append="mem=256M"
then type : lilo

It will update your config to do it automaticaly...

I hope it will work for you.

Best Regards.

Thanks for the help.

But LILO boot prompt would not stop to allow me for entry (3 seconds). Anyway to get around?

Thanks.

I tried to add "linux mem=256M" on LILO boot prompt, but I had kernel panic as "attempted to kill the idel task. iIn swapping task - not syncing..."

Any ideas?

Thanks.
