Are you developing a device driver
for a storage adapter or virtual device?
We offer precision source code to four miniport device driver
samples to
jump start your development putting you close to the finish line right
from the start.
Each sample offers the following features:
Source code for a single, self contained device
driver that needs no hardware backend to run and thus can be installed on any
system
Creates a virtual disk drive that is assigned a driver
letter and works exactly like a real disk drive
StorFile
supports Windows 7, Vista, 2003, 2008.
MiniFile supports these plus Windows 2000 and XP
StorRam supports Windows
7, Vista, 2003,
2008.
MiniRam supports these plus Windows 2000 and XP
Key Features:
Perfect
for virtual DVD drives, software RAID, devices with a network backend, or
other virtual devices.
Your device code runs at PASSIVE_LEVEL
making it ideal to call any WDK functions.
Requests can be completed with
high performance
outside of miniport context.
Provisions for overlapped request queuing
and fast, asynchronous back ends.
Kernel level code to read and write a disk file using asynchronous file
I/O.
Does not claim hardware resources.
Dual threaded design for optimum performance
on multi-core.
StorFile uses the latest Microsoft VMiniport architecture found in Windows 7, 2008, Vista SP1, and a Windows
2003 hot fix. The code utilizes
HwStorProcessServiceRequest,
StorPortCompleteServiceIrp,
and
IOCTL_MINIPORT_PROCESS_SERVICE_IRP
StorRam uses the new
storport architecture for achieving the highest possible performance. It
can also be used to test storport functionality without
needing the hardware.
MiniRam is the ideal
choice for adapters without scatter gather such as PCMCIA. MiniRam can also be used to cover the entire range of Windows versions with a single
source.
Ideal for IDE, SATA, SCSI, Fibre Channel,
Sas, and others.
StorRam
includes
WMI.
The first data block
allows the device inquiry data to be changed dynamically. The
second data block allows the miniport to send events asynchronously.
The "hello world" of
miniports; a simple skeleton ready to be filled in with your code. Learn
how simple miniports should be.
Just answer a few simple questions
in our
Miniport Selector Guide to find out
which sample and why.
How long does it take to get?
The source is delivered electronically.
You will be able to download and start using the source code instantly
after entering your order. Online ordering is safe and secure by credit card. If
you prefer, we accept purchase orders.
What comes
with each sample?
You get the carefully
articulated and well documented source code which can be built using the Windows
WDK, an INF file for installing the driver, a document which covers all you need
to know to use the source, and a pre-built ready to run driver.
What does it look like in device manager?
Are there limits on the devices?
You may define any number of adapters, buses, devices and
LUNs. The devices can be of any type (eg: scanner, printer, disk drive, optical).
What is the API like?
For StorRam/MiniRam you only need to fill in the blanks in
standard entry points that are called by storport/scsiport respectively. The
documentation has a walkthrough to help you cover each step.
For StorFile/MiniFile, your job is very easy. Simply fill in 3
functions and use one callback and your code is done. You are free to call any DDK
function or other drivers.
// your below functions are called at
PASSIVE_LEVEL. You can
// define context data for the adapter, device, and the requests
// the below callback is callable at DISPATCH_LEVEL or below
// which is convenient when you are posted by your back end.
void CompleteSrb(SCSI_REQUEST_BLOCK);
What technical support is provided?
Free support for 90 days and a full refund policy.
Are there any
royalties or other costs?
No. You are
free to modify the source and use it for as many products as you wish in any sales
volume. There is also no time limit on how long you can use the source.
