Ram problems

[Bogdan TARU]

	Hi Hackers,

 I have some weirdo problems here. A box (PIII 400Mhz, asus
 motherboard, 256MB ram) got a memory upgrade (got the 256MB out, and
 put 2x512MB in). Well, the Bios sees the correct amount of RAM (1GB),
 but FreeBSD is noticing only 256MB. 

 I have tried to add MAXMEM="2048*1024" in the kernel, also tried to
 put 'hw.physmem="1G"' in /boot/loader.conf, but with no
 result. FreeBSD is stubborn enough in detecting: 

 real memory  = 270561280 (264220K bytes)
 avail memory = 260583424 (254476K bytes)

 at each boot time. Any ideas what else I could check?

 Thanks,
