>Description:
Only 1GB RAM found (according to "dmesg | grep memory") in a 2GB system with motherboard of make and type: Gigabyte GA-E7AUM-DSH2.

>How-To-Repeat:
1. Install FreeBSD 8.1-RELEASE amd64 on machine with more than 1GB RAM and a Gigabyte GA-E7AUM-DS2H motherboard.
2. Run "dmesg | grep memory"
3. Observe output: "real memory  = 1073741824 (1024 MB)"
>Fix:
According to this webpage it's a problem with SMAP:

http://miko.org/~tatyana/tech/FreeBSD/FreeBSD_on_GA-E7AUM-DS2H_with_Over_2GB_of_RAM.html

A patch for biossmap.c is given on said website, but I've no idea if it works or is sane:

 Is there an English version of the quoted page?
 http://miko.org/~tatyana/tech/FreeBSD/FreeBSD_on_GA-E7AUM-DS2H_with_Over_2GB_of_RAM.html
 If not, can you translate it?
 
 This seems like a problem with BIOS memory reporting.
 Have you tried to update BIOS?
 Have you reported the issue to a vendor your system/BIOS?
 
 BTW, have you tried other modern operating systems on this hardware?
