Installation Notes for ADCache version 1.20

Before using ADCache, please read the documentation. The
default option settings are not the optimum for most computers.
You will want to change at least the memory size, and probably
to enable delayed-write caching as well.

Please be careful when using delayed writes. Although ADCache
has proven quite reliable in beta testing, delayed writing is
inherently more dangerous than write-through caching. Power
failures, or buggy software which locks your machine up before
the disk has been updated, can corrupt your disk and lead to the
loss of valuable data. As always, a complete and recent backup
is your best line of defense against disk failure.

With delayed writes, remember that your disk has not been
updated until the write cycle completes or the cache has been
flushed. Most beta-testers have, at one time or another, turned
off or rebooted their machines before a write has completed.
This is not a good idea! The "-f" (flush cache) option can help
here; if you have batch files that reboot your machine, insert:

adcache -f

somewhere before the reboot.

ADCache has been tested on a number of computers running a
variety of software. It works correctly with DESQview if loaded
before running DESQview. ADCache almost certainly will *not*
work with EMS emulators; don't even try it. (80386 memory
managers like 386MAX and QEMM are not emulators by this
definition; ADCache works fine with both.)

I run ADCache with these options:

adcache -a512 -w

This:

1. Allocates all but 512K of the available memory to the
cache, and,

2. Enables delayed writes with the default delay of 0.2
second.

You may also want to consider the "-i" option which will free up
several K of main memory.

My address, for bug reports, complaints, and suggestions, is
given in the documentation. Let me know what you think of it!
