- Question about SCSIport and Storport miniport
- Posted by Yang on December 1st, 2006
Hi there,
In "Designing RAID adapters to work with Windows" document, it saied that
"Windows only supports the use of SCSIport or Storport miniports for storage
adapters (except for industry-standard ATA or SATA interfaces). "
I had developed the SCSI miniport driver for my RAID adapter (IDE
interface). Here I have some questions.
Is SCSIport driver equal to SCSI miniport driver? Can I keep using my old
SCSI miniport driver? Or I must rewrite the whole driver to fit SCSIport or
Storport miniports structure?
Thanks in advance!

A SCSI miniport is a SCSIport miniport. The concept is there is a port
driver SCSIport and a miniport SCSIport miniport to go with it. Whar the
document is warning about is that until recently Microsoft allowed SCSIport
drivers to be written and certified, but now they do not.

In the mentioned context, "SCSIport driver" means "SCSI miniport linked to
SCSIPORT".
Vista has ATAPORT driver for non-standard ATA controllers, to avoid considering
them as SCSI. The standard (compatible with PC/AT task file) ATA controllers
are still serviced by ATAPI.SYS and the DMA-providing second driver.
