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