6.4.1.4: Automated memory de-fragmentation with swapout

In case you have problems with loading the ftape-internal.o module then memory fragmentation problems might (but need not ...) be the cause.

In this case, try adding

pre-install ftape-internal /usr/local/bin/swapout MEGS

to your `/etc/conf.modules' file. MEGS specifies the number of megabytes (1024 times 1024 bytes) swapout tries to allocate. This tells the modprobe program to run `/sbin/swapout MEGS' automatically before trying to load ftape-internal.o. swapout is only available on your system if you installed the ftape-tools package. Also `/usr/local/bin/' only reflects the default installation path of swapout and may be different on your system. See Optional utilities.

The hack might be necessary to decrease memory fragmentation of your computer system because ftape-internal.o needs at least 4 contiguous dma buffers of size 32kb. You may need to increase the amount of memory swapout allocates (the MEGS argument). My computer system has 20 Megs of RAM (and lots of swap space) and I go with `swapout 15'. There is more information in a separate section. See Swapout.
