BusLogic FlashPoint PCI SCSI Host Adapter Driver For DOS/WINDOWS 3.X I. Introduction =============== This README file contains compressed installation instruction and notes on configuring tunable paramenters for the BusLogic FlashPoint PCI DOS/Windows 3.X device driver. For more detailed installation instruction and other information, please refer to the manual included with the software package. II. Installation ================ There are six programs (FLASHPT.SYS, BTMDISK.SYS, BTCDROM.SYS, BTFDISK.EXE, WINASPI.DLL and VASPID.386 ) that support DOS V3.3x or above, and Windows V3.x. These programs can be applied to all of the BusLogic FlashPoint PCI SCSI Host Adapters. 1) FLASHPT.SYS Version 2.00g FLASHPT.SYS is the BusLogic DOS Device Manager that supports ASPI (Advance SCSI Programming Interface). The DOS application program uses the ASPI DOS Manager to communicate with the SCSI host adapter and allows access to additional SCSI devices connected to the host adapter. - When the system is configured with more than two hard disk drives - When the system has more than one SCSI host adapter installed - When the configured SCSI hard disk has a Target ID other than 0 or 1 - When you want to support a SCSI tape device, and - When you want to support programs that use virtual memory (i.e., Microsoft Windows V3.1, Quarterdeck QEMM 386, Qualitas 386MAX). Configuring the FLASHPT.SYS DOS Device Manager: The DOS ASPI manager has several new features along with the WIN-ASPI interface module. Most of these features are related to command line switches at install (boot) time. Along with improvements in the existing switches, additional switches are present. In order for the BusLogic ASPI DOS Manager to be loaded whenever the system is booted, the CONFIG.SYS file must contain the "DEVICE=" command. The format is as follows: DEVICE = [drive:\path]FLASHPT.SYS [optional switches] Example of CONFIG.SYS: DEVICE = C:\FLASHPNT\FLASHPT.SYS /D 2) BTMDISK.SYS Version 4.60a To access the SCSI hard disk devices that have a SCSI ID other than 0 or 1 in 'S' products or is not include in BIOS scan of 'C' products, you must install this extented hard disk driver. Otherwise, DOS cannot recognize them. In order for the BusLogic Extended Disk Driver to be loaded whenever the system is booted, the CONFIG.SYS file must contain the "DEVICE=" command and it must be loaded after the loading of ASPI DOS Manager. The format is as follows: DEVICE = [drive:\path]BTMDISK.SYS [optional switches] Example of CONFIG.SYS: DEVICE = C:\FLASHPNT\FLASHPT.SYS /D DEVICE = C:\FLASHPNT\BTMDISK.SYS /D BTMDISK.SYS Extented Hard Disk Driver can support more than one BusLogic SCSI host adapter per system. 3) BTCDROM.SYS Version 4.30g BusLogic SCSI CD-ROM device driver is compatible with Microsoft CD-ROM Extendtion V2.21 and later. In order for the BusLogic SCSI CD-ROM Driver to be loaded whenever the system is booted, the CONFIG.SYS file must contain the "DEVICE=" command and it must be loaded after the loading of ASPI DOS Manager. AUTOEXEC.BAT must contain the MSCDEX.EXE entry. The format is as follows: DEVICE=[drive:\path]BTCDROM.SYS [/D:MSCDxxx] [optional switches] where [/D:MSCDxxx] specifies the name that Microsoft CD-ROM Extention (MSCDEX.EXE) uses to find the CD-ROM Device Driver. You must use this name in configuring your AUTOEXEC.BAT file. The Microsoft CD-ROM Extention "MSCDEX.EXE" utility is required for DOS application to access the CD-ROM data files or sound. See Microsoft Manual for detailed usage on MSCDEX.EXE. The syntax for using MSCDEX.EXE is as follows: MSCDEX [parameters / optional switches] There are two ways to load the "MSCDEX.EXE" utility. Assume MSCDEX.EXE file is on drive C: root directory, device name used for BusLogic BTCDROM.SYS device driver is "BTCD00", drive letter referent by DOS is E:, number of sector buffers use by MSCDEX is 10, use Expanded memory if available, and display memory usage. Method #1: Auto load MSCDEX.EXE utility at boot time. You must add the following line to AUTOEXEC.BAT file C:\MSCDEX /D:BTCD00 /L:E /M:10 /V /E Method #2: Execute MSCDEX utility only when needed. At DOS command prompt type the following C:\MSCDEX /D:MSCD002 /L:E /M:10 /V /E Example of CONFIG.SYS: DEVICE = C:\FLASHPNT\FLASHPT.SYS /D DEVICE = C:\FLASHPNT\BTCDROM.SYS /D:BTCD00 /L Example of AUTOEXEC.BAT: MSCDEX /D:BTCD00 /L:E /M:10 /V /E Supported CD-ROM drives : 1.

SANYO CDR-400 4) BTFDISK.EXE Version 3.60a The BusLogic Extented Hard Disk Utility can be used to partition the SCSI disk devices that have a SCSI ID of 0 through 7, or 0 through 15 for wide SCS. Use the standard DOS FDISK utility to partition a hard drive with SCSI ID 0 or 1 attached to the first SCSI host adapter. This program is very similar to FDISK.EXE in DOS; however, it only supports SCSI hard disks, note that FLASHPT.SYS must be loaded first. To invoke BTFDISK.EXE, change to the directory where BTFDISK resides, then type BTFDISK at the DOS prompt. Example: C:\FLASHPNT>BTFDISK No optional switches are needed. 5 & 6) WINASPI.DLL & VASPID.386 Device Driver for Windows V3.x Windows ASPI, or WINASPI, is a windows device driver layer used for re-entrant, multi-threaded SCSI bus access for windows 3.00 or higher. The WINASPI layer provides an easy access method for Windows applications for SCSI I/O. This method is provided in the form of a DLL program (Dynamic Link Library). The name of the program is WINASPI.DLL. The DLL functions are imported by a Windows application during it's operation. The DOS Manager V4.10K and later will have the ability to run in the Windows protected mode environment. Also included for the WINASPI layer is a VxD, or Virtual Device Driver. The VxD is named VASPID.386. This code handles the locking and unlocking of the data buffers for Virtual DMA Requests during SCSI I/O. To use the WINASPI layer, the user copies the WINASPI.DLL and the VASPID.386 files to the WINDOWS directory. The DOS MANAGER (FLASHPT.SYS) may be located anywhere on the disk as long as the user specifies the appropriate path in the CONFIG.SYS file. (See FLASHPT.SYS installation section in this README.TXT file.) To activate the WINASPI layer, the installed Windows application must be configured to select the "Windows ASPI" method of access. ***** MANUAL INSTALLATION ***** First, copy WINASPI.DLL and VASPID.386 to the WINDOWS\SYSTEM sub-directory. This may be on any drive or path. Next, modify the SYSTEM.INI file to include the following statment in the [386Enh] section: "DEVICE=VASPID.386" If Windows is in standard mode WITH a memory manager, such as EMM386, loaded WINASPI will not initialize. This mode is not recomended by Windows. This error is returned as SS_ILLEGAL_MODE. If the SCSI adapter is the primary adapter and the SCSI IRQ is set at 14, then the SYSTEM.INI file MUST include the statment "VirtualHDIRQ=OFF". This statement MUST be entered in the [386Enh] section. III. Configuring Tunable Parameters ===================================== The following tunable (user-configurable) parameters are supported for: 1) FLASHPT.SYS Version 2.00g /D - This Option will display useful information about the attached SCSI target device. /L - This Option will enable support for SCSI logical units (LUNs) other than zero. The driver can recognize all eight possible SCSI LUNs on each target. /E - Rescan SCSI bus on ASPI "Request Device ID" (cmd=01), will allow dynamic rescan of the bus. The DOS manager will discard the code if /E is not requested and thus saving about 1.6k of memory requirements. /B - Allows the user to specify how many active Ccbs are allocated. Valid values are 4 (default) through 8. Increasing the count from 4 to 8 will require about 1.5k of additional memory per card. /R - Disable DOS ASPI manager from "Hard" resetting the SCSI adapter if not under BIOS control. This will be useful in multi initiator configurations. /W - Active only with /D, and allows the screen display to pause when each card is scanned. This is to prevent the displayed information from scrolling off the screen so it may be analyzed. 2) BTMDISK.SYS Version 4.60a /D - Enables verbose mode. This permits the user to see the details of the device(s) being attached to the operating system. /L8 | L16 | L32 | L64 - Set the LUN support on WIDE SCSI cards (8, 16, 32 or 64 LUN's). Devices that are not able to operate in the WIDE SCSI mode will be limited to 8 LUNs. /R - This determines the number of logical drives that will be reserved for removable media. Valid values are 1 to 24. If not specified, the default number of reserved logical drives is 1. This is used for the situation where a particular piece of media may have more than one DOS partition. /J - Forces the disk device driver to only scan 8 SCSI ID's on WIDE SCSI host adapters. /W - Active only with /D, and allows the screen display to pause when each card is scanned. This is to prevent the displayed information from scrolling off the screen so it may be analyzed. /F - Enable Floptical support. Make sure the BIOS does not also have the Floptical feature set to ON. /T - Allows the removable drive-to-ready maximum time on cartridge insertion to be set. The valid values range from 0 to 9 where the time-out is the value multiplied by 5 seconds. Thus /T2 allows about 10 seconds before the O/S is informed of a not ready condition. /Q - Allows cartridge drives to QUICKFORMAT the cartridge media. 3) BTCDROM.SYS Version 4.30g /D: - Specifies the name that MSCDEX uses to find the BTCDROM.SYS. /L - Enable SCSI Logical Unit Number (LUN) support. If enable (LUN) option, you must enable (LUN) support in FLASHPT.SYS device driver. /X - Turns on emulation to support single-session PhotoCDs for those drives that do not directly support PhotoCD. /T: - Use this option to designate the drive type your CD-ROM drive is compatible with when your CD-ROM drive is not specifically supported by the driver. MSCDEX.EXE /D: - Must be same as the name specified on BTCDROM.SYS command. /L: - Assigns DOS drive letter for CD-ROM [e.g., E,F,G,..] /M: - Number of sector buffers reseved for MSCDEX utility. /V - Display memory usage. /E - Use expanded memory if available. --- Version: $Id: readme.txt 1.1 1996/02/29 04:36:40 awin Exp $
