All of these problems can be addressed with the "mem=XXXM" boot option
(where XXX is the size of RAM to use in megabytes).
It can also tell Linux to use less memory than is actually installed.
+If you use "mem=" on a machine with PCI, consider using "memmap=" to avoid
+physical address space collisions.
See the documentation of your boot loader (LILO, loadlin, etc.) about
how to pass options to the kernel.
* Disabling the cache from the BIOS.
* Try passing the "mem=4M" option to the kernel to limit
- Linux to using a very small amount of memory.
