Hi,

recently Allan Pratt told us about the existance of a FAT-Cache called
CACHEXXX.PRG. I have seen an early version of this program (supplied
with the first beta release of TOS1.4) running. It speeded up disk
accesses very significantly compared to standard TOS1.4. So, I am eager
to have the final version of the program. But there are two big
problems:

 o     where to get it.
 oo    adjusting the XXX correctly.

According to Allan, XXX must be exactly equal to the size of the FAT.
How do I compute XXX exactly? What happens when the FAT size (in kB) is
not even? Example: my Seagate ST296N (slowww) contains 4 partitions of
21.2 each. Their FATs take 81 sectors (1 sector = 0.5 kB), hence 40.5 kB.
Do I have to take into account the sizes of all the inactive logical
devices (floppies, hd partitions), too? (I run AHDI 3.01).

Another example (taken out of the WINCAP description for the Megafile 60):
2 partitions of 30 and 34 MB. How to do this?

Related question: is it possible with tos14 to increase the cluster
size, i.e. shorten the FATs dramatically and thus speed up the hd even
further? Will CACHEXXX support such a configuration? If this is possible
--- how can I do it? Can I use Supra's SUPEDIT for this purpose?

Of course, comments of Atari officials on this subject are appreciated
very much.

Thanks

Michael Ritzert
