- SUPER PC-KWIK
-
- DESCRIPTION:
-
- Using Super PC-Kwik and Windows 3.0
-
- Disk caching with Super PC-Kwik is recommended for improved
- performance with Windows. Important notes on using PC-Kwik with
- Windows are in Chapter 13 of the DR DOS 6.0 User Guide.
-
- Although PC-Kwik attempts by default to use all available
- extended memory, it lends back up to half of that to
- applications as requested.
-
- Windows is unique in that it allocates all extended memory as it
- is loaded. Other applications use varying amounts of extended
- memory as they need it.
-
- Because Windows needs 2 Mbytes or more of extended memory to run
- efficiently in enhanced mode, you must force PC-Kwik to lend at
- least 2 Mbytes of extended memory back to Windows on systems
- with insufficient extended memory for both the cache and Windows
- (i.e., those with less than 4 Mbytes of extended memory).
-
- For example, on a system with a total of 4 Mbytes of memory (3
- Mbytes extended), Super PC-Kwik would lend only 1536 Kbytes by
- default (3072 / 2 = 1536). Because Windows prefers 2048 Kbytes
- or more, increase the default by using the following command:
-
- SUPERPCK /L:2048
-
- If total system memory is 5 Mbytes, or more, the Super PC-Kwik
- default lending of one-half of extended memory is sufficient to
- have an effective cache and run Windows in enhanced mode. If you
- run several applications through Windows and run out of memory,
- you can increase the lending amount with the PC-Kwik /L:xxxx
- switch.
-
- If total system memory is large, for example 8 Mbytes or more,
- and you use Windows extensively, turn off lending completely and
- set the allocated amount for the cache buffer. For example, on a
- system with a 10 Mbyte total (9 Mbyte extended) use the
- following PC-Kwik switch: SUPERPCK /L- /S:3072. This keeps the
- cache buffer high, while giving Windows 6,144 Kbytes of extended
- memory for its own use. Once again, enable lending if Windows is
- running out of memory.
-
-
- Using Super PC-Kwik
-
- Size of Cache
-
- Super PC-Kwik moves as much of its code into upper memory as
- possible; you do not need to use HILOAD or HIINSTALL on Super
- PC-Kwik. Super PC-Kwik will use the least amount of memory for
- its executable code if it is configured to cache in expanded
- (EMS) memory. The Super PC-Kwik code "footprint" is typically
- about 17 Kbytes in upper memory.
-
- When Super PC-Kwik is configured to cache extended memory, the
- code footprint in the first 1 Mbyte of memory varies in size
- according to the amount of extended memory that is cached.
-
- The Super PC-Kwik footprint in upper memory can be controlled by
- limiting the amount of extended memory allocated to the cache.
- If your system has more than 8 Mbytes of RAM, you might want to
- use the Super PCKwik /S:xxxx switch to limit the cache buffer
- size.
-
- The Super PC-Kwik maximum cache buffer size is 16 Mbytes.
-
- For information about running Super PC-Kwik with Windows, see
- "Running EMM386.SYS with Windows" on page 22 and Chapter 13 of
- the DR DOS 6.0 User Guide.
-
- Using Super PC-Kwik with Networks
-
- You can load Super PC-Kwik on a DOS-based network server (e.g.,
- Lantastic 4.0). However, advanced cache reads and writes should
- be disabled (use the Super PC-Kwik /H- and /D- switches.)
-
- If you are using Novell NetWare, load Novell drivers before
- loading Super PC-Kwik to permit unloading the cache. You can
- load the Novell drivers after, but you must then leave Super
- PC-Kwik in memory.
-
- Super PC-Kwik will not cache remote network drives (i.e, across
- the network). However, local drives can be cached.
-
- When used on a network, the DR DOS 6.0 operating system must
- reload COMMAND.COM after Super PC-Kwik loads. You must use the
- DR DOS SHELL and SET COMSPEC commands to point to the location
- of COMMAND.COM. See Chapter 11 of the DR DOS 6.0 User Guide for
- a discussion of how to use the SHELL command, and Chapter 10 on
- how to use the SET command.
-
- Do not use the DR DOS VERIFY=ON command when using a network as
- it will negate any gain from caching.
-
- Also, when using Super PC-Kwik, the BUFFERS=4 command in the
- config.sys file is adequate, and the FASTOPEN command is
- generally not needed.
-
- Generally, Super PC-Kwik should be loaded early in autoexec.bat.
- TSRs loaded after Super PC-Kwik must be unloaded from memory
- before Super PC-Kwik can be unloaded with the /U parameter.
-
- If you use Lotus 1-2-3 v3.1, note that it uses the Rational
- Systems DOS Extender. Use the DR DOS SET DOS16M=:384 command in
- the autoexec.bat file and use the Super PC-Kwik /R:400 switch.
-
- Troubleshooting Super PC-Kwik
-
- If, after eliminating the factors listed above, Super PC-Kwik
- still malfunctions, check the parameters used when loading Super
- PC-Kwik. Begin with the simplest settings, such as /H-, /T-, and
- /D-.
-
- If you suspect an upper memory conflict, use the Super PC-Kwik
- /&U- switch to prevent parts of Super PC-Kwik from moving into
- upper memory.
-
- If you are having problems reading a drive, try the Super
- PC-Kwik /I+, /X /I+, or /T- switches. Also, see "Upper Memory
- Conflicts" on page 17.
-
- Floppy Drive Does Not Work
-
- If you have installed Super PC-Kwik and have enabled the /D+
- switch, your disk controller must be 100% IBM compatible. Reset
- the /D+ switch to /D- (the /D# switch works on some controllers)
- to turn off PC-Kwik's advanced caching for the floppy drives
- (advanced caching for your hard drive remains in effect).
