From LINT: # MAXMEM specifies the amount of RAM on the machine; if this is not # specified, FreeBSD will first read the amount of memory from the CMOS # RAM, so the amount of memory will initially be limited to 64MB or 16MB # depending on the BIOS. If the BIOS reports 64MB, a memory probe will # then attempt to detect the installed amount of RAM. If this probe # fails to detect >64MB RAM you will have to use the MAXMEM option. # The amount is in kilobytes, so for a machine with 128MB of RAM, it would # be 131072 (128 * 1024). So (to Jason Horton) put this line in your kernel: options "MAXMEM=(128*1024)" On Wed, 19 May 1999, OCD Support wrote: > That's really strange as we have a 3.1-RELEASE running here on a Pentium Pro > 200 w/515k cache and it finds all the memory properly... wondering if maybe > it's a motherboard issue?
