Stacker is compatible with Digital Research Dos versions 5.0 and 6.0.
|
|
However, there are some special considerations when using these
|
|
operating systems.
|
|
|
|
DR DOS 6:
|
|
1. DR DOS 6 comes with its own file compression program. This
|
|
compression program cannot be used if you choose to use Stacker. Using
|
|
Stacker will give you better speed, better compression, a smaller
|
|
driver size, and more advanced features than the compression program
|
|
that comes with DR DOS .
|
|
|
|
2. Installing DR DOS 6 after Stacker is installed may require a special
|
|
procedure. See Tech023 for details.
|
|
|
|
DR DOS 5 and 6:
|
|
|
|
Using DR DOS 5 or 6, if you configure Stacker to use EMS for its cache,
|
|
or if you load the Stacker device driver into upper memory, the
|
|
following message is displayed by the Stacker device driver when you
|
|
start your computer:
|
|
|
|
"Note: In DR DOS, loading Stacker high (or using /EMS)
|
|
may slow disk access. Please see the Stacker README
|
|
file for help."
|
|
|
|
This condition can be remedied using the /ND parameter on the
|
|
STACKER.COM device line in Config.sys. Use the /ND parameter if your
|
|
hard disk controller is NOT a bus-master controller. (If you are
|
|
unsure of whether your disk controller is a bus-master, it probably
|
|
isn't.) If you DO use a bus-master disk controller and it does not
|
|
support virtual DMA, DO NOT use the /ND switch to increase disk
|
|
performance.
|
|
|
|
If you do not use the /ND parameter and wish to suppress the warning
|
|
message, place the /NW (no warning) parameter on the Stacker DEVICE
|
|
statement in the CONFIG.SYS file.
|
|
|
|
DR DOS 5:
|
|
Under DR DOS 5, the SSWAP option does not operate properly with
|
|
Stacker versions 1.0-1.11. It recommended that you upgrade to version
|
|
1.12 or 2.0 in order to SSWAP the Stacker drives.
