ok, first the problem: my computer has 1024 M of RAM installed. /proc/meminfo reports:
total: used: free: shared: buffers: cached:
Mem: 923058176 460623872 462434304 0 33697792 172601344
Swap: 3174903808 0 3174903808
MemTotal: 901424 kB
...
I'm running woody, with the 2.4.16-k7 kernel
Redhat 7.1, with a 2.4.2-2 kernel had no problem detecting all my mem.
neither did memtest86 (no errors on the full test suite)
using lilo to pass 'mem=1024M' or 'mem=0x40000000' does not change the
mem reported. same for passing those args at the lilo prompt.
however, passing 'mem=512M' does drop the mem reported, so I know the
kernel is seeing the arguments.
according to 'man bootparam'
>>
'mem=...' <snip> If you
have more than 64MB of RAM installed, you can use this
boot arg to tell Linux how much memory you have. The
value is in decimal or hexadecimal (prefix 0x), and the
suffixes `k' (times 1024) or `M' (times 1048576) can be
used. Here is a quote from Linus on usage of the `mem='
parameter.
``The kernel will accept any `mem=xx' parameter you give
it, and if it turns out that you lied to it, it will crash
horribly sooner or later. The parameter indicates the
highest addressable RAM address, so `mem=0x1000000' means
you have 16MB of memory, for example. For a 96MB machine
this would be `mem=0x6000000'.
<<
has this been changed?
any other ideas how I can get it to admit that I have more mem?
