I have three 512MB PC133 dimms in an AMD T-bird 950MHz / Abit KT7 system running RH7.0. All 1.5GB are recognized by my BIOS, but only 1.0GB is recognized by linux. I compiled kernel 2.4.0-test9 with HIGHMEM4G=y: > # CONFIG_NOHIGHMEM is not set > CONFIG_HIGHMEM4G=y > # CONFIG_HIGHMEM64G is not set > CONFIG_HIGHMEM=y > CONFIG_MTRR=y I tried appending various memory sizes during boot, but if I use anything greater than "mem=1000M" the kernel hangs during boot after the line: > Freeing unused kernel memory: 192k freed I compiled the kernel with kgcc. The appropriate lines from /usr/src/linux/Makefile: > HOSTCC = kgcc (snip...) > CC = $(CROSS_COMPILE)kgcc I have tried several tweaks to eliminate the possibility that this is a hardware problem, such as lowering my FSB speed, CPU speed, removing interleaving, and increasing DRAM delay. I see no change whatsoever. Can anyone suggest a way I can get linux 2.4 to use all of my RAM?
