LBAcache
Hard disk cache program. Improves drive performance.
Requires XMS memory, and at least a 386 computer.
To install:
lbacache [size] [DRV list] [FLOP] [TUNA] [TUNW]
Options - when loading
size
Sets cache size, in Kb, of XMS.
Default is 2MB
Maximum is 32767
Minimum is 0 (try to use as much as possible)
DRV list
Select hard disks to cache. The default is to cache
all disks, which are detected automatically.
List consists of consecutive numbers with no spaces
in between. These numbers can be:
0 C:
1 D:
...
7 J:
For example
DRV 027
Will cache the first (C:), third (E:) and
eighth (J:) drives.
DRV NULL can be used to disable hard disk caching.
FLOP
Caches the floppy disk drive(s). Use tickle
to speed floppy disks up even further.
TUNA
Tune: fully Associative mode (maybe more cache hits).
TUNW
Tune: alloc on Write mode (can be faster or slower).
TUNS
Tune: move local stack to LOW RAM (necessary for SCSI disks).
Options - after loading
INFO
Shows information and statistics about your cache(s)
STAT
Show cache statistics.
ZERO
Reset statistics counters.
SYNC
Synchronises cache data. LBAcache currently
only read caches, so this option only empties the
caches.
STOP
Closes the caches and frees XMS. The driver will also
be uninstalled unless it was loaded in config.sys.
Examples
LBACACHE
Just running the command without options will read cache all your
hard disks (if available through the BIOS) with the default
cache buffer size.
LBACACHE 5120 flop
This will read cache all hard disks and floppy disks, with 5MB
of memory for the cache buffer.
LBACACHE info
Shows information about your caches.
