128M

128M

[Vieri Di Paola]

I just bought a DIMM 128M RAM module and inserted it
in the motherboard. I took the old 2x8M SIMM modules.
However, my BIOS sees only 32M. I read though that I
can pass the kernel the argument "mem=128m" and Linux
should use all the available RAM. But this operation
leads to an error: "protection fault" and the boot
halts. Could there be a hardware problem with the DIMM
card? Or is just a BIOS thing, in which case there's
isn't anything I can do, or is there? I tried SuSE 6.3
and BestLinux Release 3 with both lilo and grub. I
passed kernel ... vmlinuz mem=128m but boot fails.
However any mem value below 32m works and the command
"top" shows the correct amount of memory.

Any suggestions?

Thanks in advance,

Vieri

It's your motherboard that can't cope with the DIMM. The only                                                          
dimm's it probably will support are 32MB DIMM's. All other                                                             
(bigger) DIMMs wil not work.
