Description
DOSCAM.SYS has all of the features and functionality of
MINICAM.SYS, but whenever one of the above features is
required DOSCAM.SYS should be loaded instead. Synchronous
negotiation will allow data transfers of 5 MB/sec. (up to 10
MB/sec. for fast SCSI, and 20 MB/sec. for fast wide SCSI).
Tagged command queuing provides a performance improvement
under multi-threaded I/O operating systems.
Installation
1. Use the COPY command to copy the appropriate driver from
the SDMS SCSI Drivers disk to your boot disk.
2. Add this line to your system’s CONFIG.SYS file:
DEVICE=C:<PATH>DOSCAM.SYS
Command Line Options
The DOSCAM.SYS device driver has several embedded functions
which can be accessed via switches on the command line.
Using the /RAMCOPY Option
RAMCOPY is an embedded command which tells the drivers to
load the ROM on the controller card into RAM, thereby increasing
the performance of the SCSI ROM.
Note:
Although it increases performance, this option will use
more RAM.
For example, the line in CONFIG.SYS that loads DOSCAM
would look like this:
DEVICE=C:<PATH>DOSCAM:SYS /RAMCOPY
Upon boot, the RAMCOPY command will be executed and ROM
will load into RAM. The first ROM will be copied into expanded
memory if available.
