-------------------------------------------------------------------------- ***** README.TXT ***** -------------------------------------------------------------------------- This README.TXT describes how to use the device driver . 1.Files This diskette contains following programs and files. SJCDAPI.SYS : CD-ROM device driver for SANYO CRD-254P. This program is a low level device driver for the interface card. README.TXT : This Text file. 2.The parameters of device drivers Here you a list of the value of all parameters for entering the device driver in the file CONFIG.SYS. These parameters should only be used by those of you who already have good experience with computers. Wrong entries can cause malfunctions and even damage! The general form of the control line for entering the device driver in the file CONFIG.SYS is: DEVICE = [Path]Device_driver_name /D:Device_name [/P:Port_address,IRQ_number] Note : The entries in square brakets are not always necessary. The parameters have the following significance: /D: Specifies the device name of the CD-ROM drive(8 characters maximum). At the CD-ROM drive usually the type name MSCD000 is used as device name, unless your application program for the reading of the CD-data explicitly requires another device name during the installation. The name must be identical with the device names given in the file AUTOEXEC.BAT behind MSCDEX.EXE. For example: DEVICE = C:\CDROM\SJCDAPI.SYS /D:MSCD000 /P:, Specifies the IDE port that is connected to the drive, and the interrupt request. 'xxx' should be the base address of IDE port. xxx = 1f0 : Primary(Channel 1) 170 : Secondary(Channel 2) 'yy' should be the interrupt channel. yy = 14 : Primary(Channel 1) 15 : Secondary(Channel 2) Only when the CD-ROM drives are connected to the primary port using interrupt channel 14 and/or the secondary port using interrupt channel 15, it is unnecessary to specify a /P parameter. When a /P parameter is specified, only that port will be searched. When a /P parameter is not specified, both the primary port and the secondary port will be searched. Example: DEVICE = C:\CDROM\SJCDAPI.SYS /D:MSCD000 /P:170,15 where: /D:MSCD000 Specifies the device name as MSCD000. /P:170,15 Port address is 170H. IRQ number is 15. 3.The parameters of MSCDEX.EXE Here you a list of the value of all parameters for entering the device driver in the file AUTOEXEC.BAT. These parameters should only be used by those of you who already have good experience with computers. Wrong entries can cause malfunctions and even damage! The general form of the control line for entering the device driver in the file AUTOEXEC.BAT is: [Path]MSCDEX /D:Device_name [/E /L:drive_letter /K /S /M:value /V] Note : The entries in square brakets are not always necessary. The parameters have following significance: /D:Device name Tells MSCDEX.EXE where to find the device driver. /E Tells MSCDEX.EXE to use expanded memory if your system is using expanded memory. (This switch requires LIM3.2 or greater) /L:(drive letter) MSCDEX.EXE starts at the drive letter specified by this switch. /K Tells MSCDEX.EXE to use any Kanji (Japanese) file structures,if present, rather than the default of standard alphanumeric file structures. /S Instructs MSCDEX.EXE to patch DOS to allow sharing of CD-ROM drives on MS-NET based network servers. /M:(value) Tells MSCDEX.EXE how much memory to allocate for caching information on the CD-ROM. /V Provides memory usage statistics, such as how much memory is used by buffers, resident data, resident code. Example: MSCDEX.EXE /D:MSCD000 /M:4 /L:E where: /D:MSCD000 identifies the drive name as MSCD000. /M:4 Memory caching is set for 8 kilobytes. /L:E the CD-ROM drive letter is E. When these modifications are completed, it will be necessary to reboot your system (by pressing Ctrl+Alt+Del). This will reconfigure your system based on the modified AUTOEXEC.BAT and CONFIG.SYS files. 4. If you connect the CD-ROM as a slave to your master IDE hard drive of the primary IDE port, and you use the CD-ROM under WINDOWS, the following command lines in the SYSTEM.INI must be edited as follows. @@ In [386Enh] section 32bitdiskaccess=off (default:off) -------------------------------------------------------------------------- Copyright(C) SANYO Electric Co., Ltd. 1994-1995 MS-DOS and MS-DOS CD-ROM Extensions are the registered trademark of Microsoft Corporation.
