100 PCA-6157/6157L User's Manual
If, for example,
• Only one host adapter is installed (or when using an NCR
based PCI SCSI embedded controller and no add in HBAs)
• Only one LUN per device will be used, and
• The bus is narrow (up to 8 SCSI IDs)
then by setting the appropriate command line options, the amount
of memory allocated will be:
Memory Allocated = 319 * 1 * 1 * 8 = 2,552 bytes (2.5 KB).
Device Drivers for Windows NT
Introduction
Windows NT provides a graphical user interface environment,
without DOS, incorporating many high level features (refer to the
Microsoft Windows NT documentation for details). I/O requests in
Windows NT are handled by an I/O manager. To address a SCSI
peripheral the I/O manager goes through the appropriate drivers
(refer to the figure below). The port driver as well as class drivers
for hard disk, floptical, CD-ROM, printer, and scanner peripherals
are provided in Windows NT Other class drivers, provided by
peripheral manufacturers, may be added to support new devices.
Tape device support is built into the operating system itself, and
does not require a class driver. NCR SDMS 3.0 provides a
miniport driver, called NCRSDMS.SYS, to complete the path to
an NCR controller or processor with an SDMS SCSI BIOS. The
following section describes this driver and its installation.
