******************************************************************* * BusTek DOS Manager Version 1.02 * ******************************************************************* There are three programs: (BTDOSM.SYS, BTMIDSK.SYS, BTFDISK.EXE) that is run only under DOS environment. These programs can be applied to all of BusTek SCSI host adapters. 1) BTDOSM.SYS v1.02 The BTDOSM.SYS's DOS device driver is used to support ASPI (Advance SCSI Programming Interface). The DOS Application program uses the ASPI DOS manager to communicate with the SCSI Host Adapter and allow access to additional SCSI devices connected to the host adapter: - When configured system with more than two hard disk drives. - Configured system with more than one SCSI host adapter. - Configured SCSI hard disk with Target ID other than 0 or 1. - To support SCSI tape device. - To support programs that use virtual memory (i.e., MS windows 3.0, Quarterdeck QEMM 386, Qualitas 386MAX ) Configure BTDOSM.SYS DOS device driver: In order for the BusTek's ASPI DOS Manager files to be loaded whenever the system is booted, the CONFIG.SYS file must contain the following DEVICE=command. The format is as follows : DEVICE = [path]BTDOSM.SYS [ optional switches] Example: CONFIG.SYS: buffers = 20 files = 20 DEVICE = C:\BTDOSM.SYS /p330 /d rem : first card DEVICE = C:\BTDOSM.SYS /p334 /d /i rem : second card if installed DEVICE = C:\BTMDISK.SYS This driver must be loaded BEFORE any extended memory managers. if you have more than one SCSI host adapters installed in the system, you need to installed BTDOSM.SYS for each SCSI host adapter with different I/O Port support. The second card's driver must add option "/i", to avoid conflict. COMMAND LINE OPTIONAL SWITCHES : The following options are available at this time, you may add it into BTDOSM.SYS driver to changer the parameters of the host adapter. /p - sets the port address that driver uses to communicate with the host adapter. This value is in HEX. Valid address are : 330 (default), 334, 230, 234, 130, 134 /d - This option will display useful information about target device, host adapter which attached to it. /l - This Option will enable support for SCSI logical units other than zeros. The driver can recognize all eight possible SCSI LUNs on each target. /x - (ISA only) This option set s AT bus master transfer (i.e. /x00) speed. This option overrides the host adapter jumper. 00 - 5.0 MB/sec, 01 - 6.7 MB/sec, 02 - 8.0 MB/sec 03 - 10.0 MB/sec, 04 - 5.7 MB/sec (default) /n - Valid bus on time are between 02 and 15 usecs. The default time is 11 usecs ( i.e.,/n11). The value is in decimal. /f - Valid bus off time are between 01 and 64 usecs. The default time is 4 usecs ( i.e.,/f4). The value is in decimal. /i - This option will disable the loading of the embedded INT 13 module. When specified, INT 13 calls are routed through the host adapter BIOS instead of INT 13 code in BTDOSM.SYS (only for SCSI disks installed with the host adapter BIOS). 2) BTMDISK.SYS v1.02 In order to access the SCSI Hard disk devices with SCSI ID other than 0 or 1, you need to install this driver device. Otherwise DOS can not recognize them. The CONFIG.SYS file must contain the DEVICE=command. The format is as follows : DEVICE = [path]BTMDISK.SYS Example : DEVICE = C:\BTDOSM.SYS /p330 /d rem : first card DEVICE = C:\BTMDISK.SYS Notes: No optional switches are needed. The BTDOSM.SYS must be installed before BTMDISK.SYS. BTMDISK.SYS device driver can support more than one Bustek SCSI host adapters installed in system. 3) BTFDISK.EXE v1.02 This utility program is used to partition the SCSI disk devices, the SCSI ID can be 0 through 7. Used standard DOS FDISK utility to partition 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, but only support SCSI devices and the BTDOSM.SYS must be loaded first. To invoke BTFDISK.EXE, simply type BTFDISK at the DOS prompt. No optional switches are needed.
