DC4000 README File Revision 1.03a On this diskette you will find device drivers for the DC4000 VL-Bus IDE Disk Controller. The second diskette is for Unix device drivers. Device Driver Diskette...............................(Version 1.50) DC4000.SYS (Version 1.30) is the driver for DOS DC4000.386 (Version 2.10) is the driver for Microsoft Windows 3.1x P4000310.DSK (Version 1.10) is for Netware 386 3.10. P4000311.DSK (Version 1.10) is for Netware 386 3.11. DC4000.ADD (Version 2.10C)is for OS/2 2.x. Unix Device Driver Diskette..........................(Version 1.20) +===============================================+ | DOS Driver for DC4000 VL-Bus IDE Controller | +===============================================+ You will need the DC4000.SYS DOS driver in the following situations: - Your DC4000 has no on-board external BIOS to take the advantage of the high speed 32-bit VL-Bus. - Your DC4000 has an on-board external BIOS but it cannot work under the default Turbo mode. You must choose the operating mode every time when you power up or reboot your system. Please follow the steps below to install the driver for DOS. - Complete the installation steps described in the DC4000 Installation Guide and boot to the DOS prompt. - Copy the driver DC4000.SYS to your system in the appropriate path. - Add this following statement to your CONFIG.SYS file: device = [drive:][\path\] DC4000.sys [/F or /T] [/W] where [drive:] and [\path\] point to the directory that contains the the DC4000.sys file. The parameters F, T and W define the operating mode as follows: F : DC4000 working in the Fast mode T : DC4000 working in the Turbo mode (default operating mode) W : DC4000 working in the 16-bit data access mode. Certain motherboard CPUs (for example, IBM 486 SLC2) have a 16-bit external data bus and cannot operate in the default 32-bit data access mode. Under Fast(F) mode, the DC4000 supports 32-bit VL-Bus I/O. Under Turbo (T) mode, the DC4000 not only supports 32-bit VL-Bus I/O but also read/write multiple commands. Since read/write multiple commands allow the host to access disk data in multiple-sector blocks, the Turbo mode will usually be faster. Note that not all IDE drives support the read/write multiple commands. Usually, you may set your DC4000 to run under the Turbo mode. When your system is brought up, the driver DC4000.sys will automatically issue an Identify Drive command to check if the attached IDE drive(s) support the read/write multiple commands. In the case your drive(s) does not support the read/write multiple commands, the DC4000 will automatically be forced to run under the Fast mode. Note: Some IDE drives may not support the read/write multiple commands properly. If your DC4000 can not access the attached drive(s) properly under the default Turbo mode, you have to specify the parameter as "F". Example: If the DOS driver DC4000.SYS resides in the root directory of the drive C:, and you want your DC4000 to run under TURBO mode, add the following statement to the file CONFIG.SYS. device= c:\DC4000.sys Add the following statement if your DC4000 has to run under the Fast mode: device= c:\DC4000.sys /f +========================================================+ | Microsoft Windows version 3.1 disk driver for DC4000 | +========================================================+ The file DC4000.386 is the Microsoft Windows 3.10 / Windows for Workgroups 3.11 disk driver for the DC4000 controller. Microsoft Windows 3.1x offers 32-bit Disk Access Mode which is supported by a device driver called "WDCtrl." This device driver should support controllers like the DC4000 which are compatible the WD1003 standard. In cases where Windows cannot initialize in 32-bit Access Mode, this Promise device driver can be used to replace the "WDCtrl." Please follow the steps below to install the driver for DC4000. 1. Copy the driver DC4000.386 to your Windows\System subdirectory. It is recommended that the driver DC4000.386 be copied to the Windows SYSTEM directory. 2. Check if the following lines exist in the [386Enh] section of your SYSTEM.ini file. [386Enh] 32BitDiskAccess=ON device=*int13 If the statements do not exist, add them into the [386Enh] section. If the statements exist, but 32BitDiskAccess is set to "OFF", you need to change it to "ON". 3. Delete or remark(using ";") the "device=*wdctrl" device setting. Delete/remark the command line "device=*wdctrl" from the [386Enh] section of your SYSTEM.INI file, if it exists. 4. Install the virtual device "DC4000.386". Add the following command lines in the [386Enh] section of the SYSTEM.INI file: device=[drive:][\path\]DC4000.386 DisksAccessMode=[Fast or Turbo] [/W] The [drive:] and [\path\] point to the directory that contains DC4000.386 file. Note: The path statement is not required if the driver is copied into the Windows SYSTEM subdirectory. The setting of disk_access_mode specifies the disk access mode as follows: Fast : DC4000 working in the Fast mode Turbo : DC4000 working in the Turbo mode (default) W : DC4000 working in the 16 bit data access mode (If motherboard CPU has a 16-bit external data bus. for example, IBM 486 SLC2....) Note : If no parameter is specified, the DC4000 will be set to run under the default Turbo and 32 bit data access mode. Under Fast mode, the DC4000 supports 32-bit VL-Bus IO. Under Turbo mode, the DC4000 not only supports 32-bit VL-Bus IO, it also supports the read/write multiple commands. Since read/write multiple commands allow the host to access disk data in multiple-sector blocks, the Turbo mode will usually be faster. Note: Not all IDE drives support the read/write multiple commands. Usually, you may set your DC4000 to run under the Turbo mode. When your system is brought up, the driver DC4000.386 will automatically issue an Identify Drive command to check if the attached IDE drive(s) support the read/write multiple commands. In case your drive(s) does not support the read/write multiple commands, the DC4000 will automatically be forced to run under the Fast mode. Note: Some IDE drives may not support the read/write multiple commands properly. If your DC4000 can not access the attached drive(s) properly under the default Turbo mode, you have to specify the parameter as "Fast". +=======================================+ | Netware 3.xx disk driver for DC4000 | +=======================================+ Please follow the steps below to install the driver for Netware 3.10. Use P4000311.DSK instead of P4000310.DSK in the following procedure when you are installing Netware 3.11. Note that you don't need to load the ISADISK.DSK when you are installing the Netware driver for DC4000. 1. After you have installed the DC4000, bring up the Netware server until the prompt ":" appears on the screen. 2. Type the following command after the ":" prompt: :load P4000310 [/F or /T] [/W] port=1f0 int=e The parameters F, T and W define the operating mode as follows: F : DC4000 working in the Fast mode T : DC4000 working in the Turbo mode (default operating mode) W : DC4000 working in the 16 bit data access mode (If motherboard CPU has a 16-bit external data bus. for example, IBM 486 SLC2....) Note: If no parameter is specified, the DC4000 will be set to run under the default Turbo and 32 bit data access mode. Under Fast(F) mode, the DC4000 supports 32-bit VL-Bus IO. Under Turbo (T) mode, the DC4000 not only supports 32-bit VL-Bus IO, it also supports the read/write multiple commands. Since read/write multiple commands allow the host to access disk data in multiple-sector blocks, the Turbo mode will usually be faster. Note that not all IDE drives support the read/write multiple commands. Usually, you may set your DC4000 to run under the Turbo mode. When your system is brought up, the driver will automatically issue an Identify Drive command to check if the attached IDE drive(s) support the read/write multiple commands. In case your drive(s) does not support the read/write multiple commands, the DC4000 will automatically be forced to run under the Fast mode. Note: Some IDE drives may not support the read/write multiple commands properly. If your DC4000 can not access the attached drive(s) properly under the default Turbo mode, you have to specify the parameter as "F". +==========================+ | IBM OS/2 2.x disk driver | +==========================+ DC4000.ADD is the driver for the IBM OS/2 2.0 and IBM OS/2 2.1x. Please read all the information before preceding with the install.
