- Preface :
- =========
-
- Have you an experience running MS-Windows(TM) without disk caching drivers
- (without SMARTDRV command in AUTOEXEC.BAT) ? What a terrible hard work for
- hard disk in this situation ?
-
- How about your CD-ROM drives ?
-
- It seems to be over loaded when running MS-Windows (TM) multimedia
- applications or titles (such as Microsoft(R) BookShelf(TM)).
-
- TURBOCD (TM) CD-ROM cache device driver is target to resolve this problem.
- TURBOCD can easily increase CD-ROM performance by 2 to more than 30 times
- faster, and free as much available conventional memory as without it.
-
-
- System requirement :
- ====================
-
- To get the benefit from TURBOCD, you need:
-
- 1. A CD-ROM drive compliant to MPC (Multimedia PC)
-
- 2. At least 256 KB of extended memory.
-
-
- TURBOCD Overview
- ================
-
- TURBOCD is a professional and experienced cache device driver for CD-ROM
- devices. It will improve CD-ROM performance from 2 to more than 30 times
- faster than without it dependent on applications. (please refer to "test
- report section" in this file).
-
- In addition to good performance improvement, TURBOCD also has many
- other smart features. TURBOCD has an integrated installation program,
- well test with existing hardware, software and related systems,
- has on-line help, device driver status and statistics report program,
- intelligent memory allocation strategy, easy to unload from system,
- and plus all above, TURBOCD may incredibly use none extra conventional
- memory of system !
-
-
- TURBOCD features :
- ==================
-
- 1. Dramatically improve CD-ROM device performance from 2 to 30
- times faster.
-
- 2. TURBOCD is a professional, experienced product and support the
- largest cache size up to 64 MB.
-
- 3. Command line startup, with unload capability.
-
- 4. Integrated with install, status check, unload, on-line help,
- and others.
-
- 5. Automatically detect and allocate memory.
-
- 6. Very small and efficient resident code (TSR), at least 7 KB.
-
- 7. Can configured to eat nothing of extra conventional memory.
-
-
- Installation
- ============
-
- It is quite easy to install the TURBOCD CD-ROM device driver, run next
- at DOS command prompt :
-
- > TURBOCD /SETUP
-
- Follow the setup program to install TURBOCD onto your system. If you want
- to change the configuration of TURBOCD, you can run setup program again,
- TURBOCD setup program will keep track of your current setting and setup the
- new configuration.
-
- Note : You have to reboot to make the new setup active.
-
-
- TURBOCD command syntax :
- ========================
-
- TURBOCD has the following command line syntax :
-
- 1. > TURBOCD /SETUP : setup onto your machine.
-
- 2. > TURBOCD [dddddd]: Start TURBOCD (TSR) and use [dddddd] KB of memory
- as cache, ddddd from 256 to 65535 KB. [dddddd] is
- option, see note for detail description.
-
- 3. > TURBOCD /UN : unload from memory, free all memory used by TURBOCD
- to system.
-
- 4. > TURBOCD [/? | /ST | /ON | /OFF | MAX | MIN]
-
- /? or /ST : Help or show TURBOCD driver status
-
- /ON or /OFF : Enable or Disable TURBOCD cache driver
-
- /MAX or /MIN : Cache all or directory only, Default is MAX if
- cache buffer size > 512 KB
-
- Note : TURBOCD is started by command line "TURBOCD [dddddd]", where ddddd
- size is optional, it tells TURBOCD allocate how much of system
- XMS memory for the CD-ROM buffer. The larger the buffer the better
- CD-ROM performance gained. The size can from 256 to 65535 (256 KB to
- 64 MB). If you do not specify dddddd, TURBOCD will use the following
- table to allocate system RAM (XMS RAM) as cache buffer.
-
-
- Free XMS memory TURBOCD allocates
- ----------------------------------------------------------------
- less than 256 KB none (fail to load)
- less than 1024 KB allocate all
-
- > = 1024 KB allocate half of available
- with maximum buffer size = 2048.
-
- Note : If you want to allocate cache buffer size larger than 2048 KB, you
- have to specify the [dddddd]. TURBOCD will allocate maximum of 2048
- KB without this parameter.
-
- Note : /UN unload command will free all of the memory occupied by TURBOCD,
- include cache buffer and program code.
-
- Note : /MAX will cache all of the data read from CD-ROM, and /MIN cache
- the directory information of CD-ROM only. You can change
- it at any time. By default, TURBOCD will use /MAX methodology
- except cache buffer size less than 512 KB.
-
-
- Free more conventional memory
- =============================
-
- After you have installed the TURBOCD CD-ROM device driver, you can release
- the buffer allocate for MSCDEX.EXE (TM). There is an "/M:number" parameter
- with MSCDEX.EXE command line. The "number" means to allocate how many 2 KB
- buffers for MSCDEX, which allocates memory from conventional memory
- (under 640KB) and that decreases your free conventional memory. In general
- the buffers allocated are 12 ("/M:12"). If we install TURBOCD onto system,
- then these buffers have no benefit to CD-ROM performance according to the
- speed test, so actually we can decrease it to 4 without inferring performance
- of CD-ROM drives if TURBOCD is loaded.
-
- If we reduce the number to 4 then we can free 8 buffer space (16 KB)
- of conventional memory from MSCDEX. We recommend to update the MSCDEX buffer
- number to 4 if you need more conventional memory. Next is an example MSCDEX
- and TURBOCD commands in AUTOEXEC.BAT after you installed TURBOCD and
- changed MSCDEX buffer number to 4:
-
- in AUTOEXEC.BAT
-
- C:\DOS\MSCDEX.EXE /M:4 /D:SONY_000
- C:\TURBOCD.EXE 1024

-
- Performance test report :
- =========================
-
- Please find detailed performance test report in file "report.txt"
-
-
- TURBOCD developer :
- ===================
-
- TURBOCD project leader had been given an excellent comment for his disk
- cache driver developed for a famous world wide PC company in 1988. In the
- LanTime NSTL test reported in 1990, his cache driver was outstanding the
- other competitors, such as Microsoft SMARTDRV, and Multisoft PCKwirk cache.
-
-
- Technical highlights :
- ======================
-
- Intelligent cache method used, which include the read-ahead, data hashing
- technology, priority data handling, and many others.
