- Installation Notes for ADCache version 1.22
-
- *** NOTE: version 1.22 is a maintenance release of ADCache. It
- *** corrects a mistake which prevented using ADCache on PC and
- *** XT systems, as well as one which could sometimes cause
- *** delayed writes to fail with some EMS 4.0 drivers. A more
- *** complete update, with new features, will be released around
- *** the end of July 1990.
-
- 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!
