[rhn-users] grub does not honor mem=xxxM request

Thu Jan 12 22:14:37 UTC 2006

I have a dual opteron 275 box (iwill dk8x and 8x512MB of
reg/ecc pc3200) with RHEL 4 AS installed.  I have the latest
kernel (2.6.9-22.0.1.ELsmp.  It shows 3.09GB of RAM in top.  I
have changed the software and hardware memory remap functions
in the BIOS and software on/hardware off gives 4096MB of NVRAM
during POST.  However, top still shows 3.09GB (with and
without mem=4096M in the boot line).  Am I using this option
incorrectly or is there something else I can do?
