Linux only recognizes 64MB RAM on HP Netserver

Linux only recognizes 64MB RAM on HP Netserver

Post by Joe Chu » Sat, 21 Oct 1995 04:00:00



Greetings. I'm running Linux1.2.13 (Slackware) on a HP Netserver (100MHz
pentium). I have 128MB RAM in it, which is correctly recognized by the
BIOS at boot time, but Linux only recognizes 64MB:

# more /proc/meminfo
        total:   used:    free:   shared:  buffers:
Mem:  65474560 63508480  1966080 20041728 48312320
Swap:        0        0        0

Anyone ever see something like this before?? Any ideas?

Thanks

If you just want to get things running, put the line

  append = "mem=128M"

in your /etc/lilo.config to inform the kernel about the real mem size,
and rerun "lilo".

Sure. This is a frequently asked question around here.
While the BIOS tests all the memory, it has no way of reporting more than
64M. Since Linux get its memory info from the BIOS it thinks there is
only 64M.

Solution: use a kernel parameter to tell the kernel how much memory is
actually there. For example at the LILO boot prompt...

boot: linux mem=128M

Should solve the problem. When this works the put the line in the
/etc/lilo.conf file with an append statement. Read the LILO documentation
for more info.

Hope this helps,
