DC2000 README File Revision 1.03 On this diskette you will find device drivers for the DC2000 VL-Bus IDE Disk Controller. DC2000.SYS (Version 1.40) is the driver for DOS DC2000.386 (Version 1.20) is the driver for Microsoft Windows 3.1 N2000310.DSK (Version 1.10) is for Netware 386 3.10. N2000311.DSK (Version 1.10) is for Netware 386 3.11. +===============================================+ | DOS Driver for DC2000 VL-Bus IDE Controller | +===============================================+ The file DC2000.SYS is the DOS driver for the DC2000 disk controller. You will need it in the following situations: - Your DC2000 has no on-board external BIOS to take the advantage of the high speed 32-bit VL-Bus. - Your DC2000 has an on-board external BIOS, but it can not work under the default Turbo mode. You need to select the operating mode every time when you power up or reboot your system. Please follow the steps below to install the driver for DOS. - Follow the installation steps as described in the DC2000 Installation Guide and bring up your DC2000. - Copy the driver DC2000.SYS to your system in the appropriate path. - Add the following statement to your CONFIG.SYS file: device = [drive:][\path\] DC2000.sys [/F or /T] [/W] where [drive:] and [\path\] point to the directory that contains the the DC2000.sys file. The parameters F, T and W define the operating mode as follows: F : DC2000 working in the Fast mode T : DC2000 working in the Turbo mode (default operating mode) W : DC2000 working in the 16 bit data access mode (If motherboard CPU has a 16-bit external data bus. for examples, IBM 486 SLC2....) Note: If no parameter is specified, the DC2000 will be set to run under the default Turbo and 32 bit data access mode. Under Fast(F) mode, the DC2000 supports 32-bit VL-Bus IO. Under Turbo (T) mode, the DC2000 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 DC2000 to run under the Turbo mode. When your system is brought up, the driver DC2000.sys 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 DC2000 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 DC2000 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 DC2000.SYS resides in the root directory of the drive C:, and you want your DC2000 to run under TURBO mode, add the following statement to the file CONFIG.SYS. device= c:\DC2000.sys Add the following statement if your DC2000 has to run under the Fast mode: device= c:\DC2000.sys /f +========================================================+ | Microsoft Windows version 3.1 disk driver for DC2000 | +========================================================+ The file DC2000.386 is the Microsoft Windows 3.1 disk driver for the DC2000 controller. While Microsoft Windows version 3.1 supports 32-bit disk access, the disk data transfer between host and the IDE adapter is still limited by the 16-bit ISA bus. If you want to speed up your hard drives under Windows through the 32-bit VL-Bus, you will need this driver. In addition, the driver also allows your host to access the disk data through the faster "read/write multiple" commands. Please follow the steps below to install the driver for DC2000. 1. Copy the driver DC2000.386 to your system in the appropriate path. It is recommended that the driver DC2000.386 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 the "device=*wdctrl" device setting. Delete the command line "device=*wdctrl" from the [386Enh] section of your SYSTEM.INI file, if it exists. 4. Install the virtual device "DC2000.386". Add the following command lines in the [386Enh] section of the SYSTEM.INI file: device=[drive:][\path\]DC2000.386 DisksAccessMode=[Fast or Turbo] [/W] The [drive:] and [\path\] point to the directory that contains DC2000.386 file. Note that the setting must specify the full path of the device driver DC2000.386. The setting of disk_access_mode specifies the disk access mode as follows: Fast : DC2000 working in the Fast mode Turbo : DC2000 working in the Turbo mode (default) W : DC2000 working in the 16 bit data access mode (If motherboard CPU has a 16-bit external data bus. for examples, IBM 486 SLC2....) Note : If no parameter is specified, the DC2000 will be set to run under the default Turbo and 32 bit data access mode. Under Fast mode, the DC2000 supports 32-bit VL-Bus IO. Under Turbo mode, the DC2000 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 DC2000 to run under the Turbo mode. When your system is brought up, the driver DC2000.386 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 DC2000 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 DC2000 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 DC2000 | +=======================================+ Please follow the steps below to install the driver for Netware 3.10. Use N2000311.DSK instead of N2000310.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 DC2000. 1. After you have installed the DC2000, bring up the Netware server until the prompt ":" appears on the screen. 2. Type the following command after the ":" prompt: :load N2000310 [/F or /T] [/W] port=1f0 int=e The parameters F, T and W define the operating mode as follows: F : DC2000 working in the Fast mode T : DC2000 working in the Turbo mode (default operating mode) W : DC2000 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 DC2000 will be set to run under the default Turbo and 32 bit data access mode. Under Fast(F) mode, the DC2000 supports 32-bit VL-Bus IO. Under Turbo (T) mode, the DC2000 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 DC2000 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 DC2000 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 DC2000 can not access the attached drive(s) properly under the default Turbo mode, you have to specify the parameter as "F". +================================+ | UNIX Driver V1.1 for DC2000 | +================================+ ******** Install UNIX Driver ******** This driver is for AT&T UNIX SVR 4.0 and SCO UNIX 3.2.4.
