CDRcache
CD drive cache program. Improves drive performance.
Requires XMS memory, and at least a 386 computer.
In config.sys, either
device=cdrcache device name cachesize
or
devicehigh=cdrcache device name cachesize
Load CDRcache after loading your CD-ROM device driver
(usually atapicdd.sys).
Parameters
device
The same name of the device that you previously loaded with your CD-ROM
device driver.
name
A new name which you will pass to shsucdx in
the autoexec.bat
cachesize
Specifies the cache buffer size in kilobytes. The
cache is stored in XMS memory.
Minimum value is 128
Maximum value is 65280
Values below 100 are valid for compatibility with previous
versions of CDRcache. Below 100, sizes are interpreted as
multiples of 0.25MB.
Controlling the driver after loading
Use:
echo command > name
Where name is the parameter passed to CDRcache
(see above).
Command is:
F - Flush the cache
S - show Statistics
I - show statistics with extra technical Information
C - Clear statistics
Q - Quiet mode
N - Normal verbosity
V - Verbose/trace mode
0 - stop caching
1 - continue caching (after stop for instance)
? - show help text
Examples
In config.sys:
DEVICE=c:\fdos\bin\Atapicdd.sys /D:FDCD0000
DEVICE=c:\fdos\bin\CDRcache.sys FDCD0000 CDRCACH$ 2048
then in autoexec.bat:
c:\fdos\bin\shsucdx /D:CDRCACH$
This allocates a 2048KB (2MB) cache buffer for a single IDE CD drive.
