If you mount a partition, which you have to do if you are using FFS, you can
include those two lines into your Mountlist:
Buffers = <n>
BufMemType = 1

These Buffers are 512 bytes each and from my experience I suppose that they are
used for File Info Blocks only, too. So what is the need for Blitzdisk?

BTW, if someone could enlighten me about the purpose of the "BufMemType" entry,
I'd much appreciate it. I have tried both 1 and 0, and each time the buffers
are allocated from FastMem, which of course is the right thing to do, I guess,
but then what the heck is this BufMemType entry for?
I'd very much appreciate any pointers to information about these things, as I
have not found details in the RKM manuals or anywhere else.
