SPEED CACHE 4.25B - Disk Cache Utility
for the DEC Rainbow
Speed Cache is a TSR program. As such it can be installed at any time
including automatically in your AUTOEXEC.BAT file if desired. To install,
use the following lines:
MEDIACHK OFF
(recommended if caching RX50 drives)
SCACHE xxx [options]
(Where xxx is desired cache size in Kbytes and
[options] represents one or more of the options
listed below)
Speed Cache can also be installed from the command line with
SCACHE xxx [options]. xxx should be a mulitple of 16K or it will be rounded
up to be a multiple of 16K. Speed Cache will always reserve 128K of RAM for
applications. Don't be afraid to make your cache sixe as large as possible.
If you have 896K on your system and a program that only requires 256K for
itself, you can set Speed Cache for 640K with no danger of running out of
memory. Help can be accessed by typing SCACHE H or SCACHE ?.
OPTIONS:
The following can only be used at time of installation:
L (default) = instructs Speed Cache to link to the drive
-L = tells SC not to link to drive
The following can only be used once SC is installed:
S = display status of the cache
U = uninstall Speed Cache (turn off TSR)
F = flush the cache of all data sectors and statistical info on
the designated drive
R = reset entire cache
The following can be used during or after installation:
A = cache to activate or reactivate drives
-A (default) = deactivate drives
O (default) = enables caching of the drive
-O = inhibits caching of and ADDITIONAL sector of the drive
C (default) = check for change of media for the drive
-C (default for hard drives only) = no check for media change
P = tells SC to write protect the RAMDRIVE
-P (default) = no write protect
W = become a write-through cache
-W (default) = cache to read data only
G=n instructs cache to allow group sector reads no greater than
"n" to be cached. The default for n is 128.
