Are you trying to find out how much memory is in the computer during the install??
If so, then if there is an option to open a terminal during the install, simply run the following command:

Code:

free -m

This will give the memory usage info in megabytes (-m). For example, from my installed Lubuntu system:

Code:

tom@desktop:/data$ free -m
             total       used       free     shared    buffers     cached
Mem:          3954       3695        258          0        240       1812
-/+ buffers/cache:       1642       2311
Swap:          953          0        953

In the total column, you see that I have 3954 megabytes of memory, or about 4GB, which is what is in my computer.
The command cat /proc/meminfo will also list the total amount of memory (in kilobytes) along with a lot of other parameters. For example:

Code:

tom@desktop:/data$ cat /proc/meminfo 
MemTotal:        4048980 kB
...

Also, you could open a terminal from any Linux live CD and run those commands to get the memory info.

I'd start at bios.

I recommend:
- look at the BIOS (already recommended)
- or start an UltimateBootCD (look at "hdt" on it which analyse your Hardware including RAM; or start a RAM test of that CD)
- or start "hdt" or "memtest" from anywhere else (USB, SD, CF)
