Linux: 256 MB RAM, but reports only the top 64 available [pc bios] [256 mb ram]

Q: I have a 256 meg stick of RAM in Linux PC. BIOS detects the sound when the computer posts.

According beyond says

Mem: 64044k av, 62 388, used, 1656k free, meg 97,750,397,750,364? Why is not entirely out to see?

Re:If i'm not mistaken Abit had some releases of their Bioses for the BH6 that said "fixed the memory limit on linux". You may want to try to update your mobo bios to the latest.

Re:I believe that it is just

append "mem=256M"

I don't think that the MEM is capitalized and you just need an M, not MB, if I remember correctly.

This is not a general problem with linux, it only happens with certain
BIOSes. I have 192 MB in my machine and I do not need an append line.


Re:append = "MEM=256MB"

Add that after the image= line for your linux boot and before the read-only line. Oh, this should be done in /etc/lilo.conf. Of course this will only work if you use lilo, if you are a grub user then you will have to figure out how to pass kernel parameters to grub. If you already have an append = line then add MEM=256MB to the end of it. Like if you had something that said:

append = "ide2=0×1410,0×1404 ide3=0×1408,0×1400"

then you would edit it to say this:

append = "ide2=0×1410,0×1404 ide3=0×1408,0×1400 MEM=256MB"

you might want to make sure that MEM is suppose to be in caps also…. hope this helps.


Re:LILO: linux mem=256MB

or edit your lilo.conf
add this line to the file

append = 256MB

read up on it, don't remember too well


Re:if you have over 64 mb of ram you have to tell linux itself how much ram you have. i recall theres a file you have to edit but i dont recall which one and how you edit it. if you dont have a video card with onboard memory you probably want to tell linux that you have 8mb less ram…just to be safe.
