Ask your <whoever gave that order> why such an outdated and almost EOL version should be installed. You won't be able to get any updates for it sooner rather than later. You should be running a 64-bit version of FreeBSD 7/8 on that.

I know an informed 'should' is a more bendy concept than a manager shouting 'should' at you, but try.
 
32-bit version of the OS can only use 4 GB of RAM, unless using the PAE hacks, which are not known to be stable.

If you want to use more than 4 GB of RAM, then install a 64-bit version of the OS.
 
I can't install 64bit version coz our software only can run on 32 bit version :(

now i put 4 GB only but it's only show 2 GB when i install Ubuntu 64 bit i can see 4 GB and if i put all memory i can see 8 GB.
 
In /usr/src/sys/amd64/conf/GENERIC:

Code: 
options         COMPAT_IA32             # Compatible with i386 binaries
 
Really thanks for all reply.

After i install our software on freebsd 6.4 i386. i got this error,

Your BIOS is doing bad things.  Actually, there is a known workaround for this 
specific problem for Compaq BIOS's: [color="RoyalBlue"]try changing the ATA devices to use simple DMA or PIO rather than Ultra DMA.[/color]

[BIOS] tries to see if it is running in protected mode with paging enabled so it 
can walk the page tables to extract physical addresses for its DMA.  The vm86 
monitor that our boot code uses doesn't let the BIOS read the page table 
pointer register (%cr3) so it blows up.

Your BTX crashed at the same instrustion (eip), so it might be a related problem with a related solution.
