	I thought I was up the proverbial shit creek when I brought
    my 'nd' server up with a 5MB partition (that is, a 5MB file) because
    Seeking took forever (i.e. scanning the side sectors for random Seek()
    calls).

	It turns out that by specifying enough buffers  (~100 in this case),
    all the side sectors get cached and the FFS no longer needs to go to disk 
    to scan them.  So, thanks CATS for not caching data sectors!

	So now I have a working server-client ND type disk for a diskless
    Amiga over the parallel port.  BTW rewrote some stuff and am now getting
    12+K/sec instead of 9+K/sec.  A little code smoothing and I will post it
    to the moderator (Beta this time).

    (p.s. side sector = sector block pointer table)

	Bug in format:  Apparently Format reads block 0 of the disk before
    it does anything.  Apparently if I put 'DOS\1' all through block 0
    Format doesn't crash.  Before block 0 was simply cleared (all zeros) and
    Format would either give up with some error or crash.

	Format isn't supposed to do that ...

    DiskPerf results are now (5MB FFS partition)

	create 4 files/sec, delete 8 files/sec
	directory scan: 100 entries/sec
	seek/read test:  23 seek-reads/sec
