What Effect Does a Memory Upgrade Have/Is All Memory Recognized?
Kernels are now available that will recognize either 32 or 64 MB of RAM. If you have upgraded your netBook to have 64 MB of RAM, a linux kernel is available that will recognize this. If a Series 7 kernel is used, then only 16 MB of memory is available. At present, separate kernels are required to recognize these various memory configurations; please get the kernel appropriate to your netBook (the effect of a 64MB kernel on a 32MB netBook is unknown, and you probably don’t want to find out).Unfortunately, it appears that the netBook or kernel ramdisk has problems – attempting to transfer large amounts of data (10-15 MB) to the netBook (to a separate ramdisk, say) will gradually consume all the memory and cause the system to freeze up. I think this may be a bug in the ramdisk driver or netBook’s memory patch. Using a ramfs or tmpfs (the preferred filesystem), rather than ramdisk, seems to work o.k.
