I know that you have answered the question regarding how to get Linux see 128M RAM before, however I still just get linux to see about 13M of RAM (13M is what the command top and procinfo display) where I have 128M installed on the machine.
Some machine details: Pentium II 350 with an EPOX motherboard and 128M 100MHZ RAM, running Redhat 6.0 with kernel 2.2.5. I use lilo to boot and I include a snippet from the lilo.conf
> image=/boot/vmlinuz .... > append="ram=128M" > read-only
Any ideas from your side would be greatly appreciated.
It sounds like your system is "seeing" (using) all 128Mb of RAM and that you are probably must misreading the output from 'top' and/or 'procinfo'
Here's an excerpt from 'procinfo' on one of my systems:
Linux 2.2.0 (root@canopus) (gcc 18.104.22.168) #8 [canopus.(none)] Memory: Total Used Free Shared Buffers Cached Mem: 63200 61304 1896 25688 3940 13192 Swap: 104416 0 104416
Note that it lists 63200 as my total memory (this is a 64Mb system.
Here's a screen shot from the top of a 'top' session (cut using the 'screen' cut and paste features):
3:27am up 4 days, 18:04, 8 users, load average: 0.00, 0.00, 0.00 57 processes: 55 sleeping, 1 running, 0 zombie, 1 stopped CPU states: 0.9% user, 1.1% system, 0.0% nice, 98.0% idle Mem: 63092K av, 61224K used, 1868K free, 39184K shrd, 1384K buff Swap: 231276K av, 24800K used, 206476K free 16788K cached
This is another 64Mb system.
If you really aren't seeing more than 13Mb (more likely to be 16Mb actually) on your system then you may want to double check your CMOS settings and consider testing the hardware using some other OS.
The append= directive should no longer be necessary with newer (2.2.x and later) kernels. However, you didn't mention which kernel you're using and specifying a correct value won't hurt.
