SCSI API

[Guest]

Firstly: Under Win9x the WN32ASPI.DLL supplied by Adaptec provided the API
interface between the SCSI subsystem and the applications. How is this
accomplished under Windows 2000?

Secondly: Can the WN32ASPI dll run within Windows 2000 without causing
conflicts?

Win2K doesn't support ASPI.

No, but you can download an ASPI driver for Win2K from Adaptec. Last time
I went down that road, the driver that was easy to find on the Adaptec web
site didn't work but there was another one hidden somewhere on the site which
did work. I'm not sure what the current status of these drivers is. If you
can't locate a version which works, let me know.

Dear Gary,
Thank you for the information regarding ASPI drivers for Win2K. I shall take
a look at what Adaptec has to offer.
Now regarding Win2k's native SCSI support. Do you know of a technical
publication that would provide details of the Win2K SCSI API and how to call
the necessary functions that it contains?

Regards,

Rupert.

Take a look at "SCSI Port I/O Control Codes" in MSDN and specifically at
"IOCTL_SCSI_PASS_THROUGH".
