Memory prices seem to be falling and I am contemplating buying more memory.
In Documentation/Configure.help, it says the following:
: Limit memory to low 16MB : CONFIG_MAX_16M : This is for some buggy motherboards which cannot properly deal with : the memory above 16MB. If you have more than 16MB of RAM and : experience weird problems, you might want to try Y, everyone else : says N. Note for machines with more that 64MB of RAM: in order for : the kernel to be able to use the memory above 64MB, pass the command : line option "mem=XXXM" (where XXX is the memory size in megabytes) : to your kernel during boot time. See the documentation of your boot : loader (lilo or loadlin) about how to pass options to the : kernel. The lilo procedure is also explained in the SCSI-HOWTO, : available via ftp (user: anonymous) in : sunsite.unc.edu:/pub/Linux/docs/HOWTO. You also need at least 512kB ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : of RAM cache if you have more than 64MB of RAM. Some other things ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : to try when experiencing seemingly random, "weird" problems: 1) : passing the "no-hlt" option to the kernel 2) passing the "no-387" : option to the kernel 3) passing the "mem=4M" option to the kernel : (thereby disabling all but the first 4M of RAM) 4) disabling the : cache from your BIOS settings 5) exchanging RAM chips 6) exchanging : the motherboard 7) committing suicide.
Is the line about needing a 512kB cache true?
In theory, my motherboard can hold up to 128MB of memory, yet I am fairly certain that I am limited to a 256kB cache. (I have a Plato motherboard.)
