The Promise driver is what helps make a proper entry in
Device Manager, for the chip. Before the driver is installed,
it'll be some kind of unknown storage device. When either the
ATA or the RAID driver is used, I think both of those are
SCSI Miniport drivers, meaning they make the storage device
appear as "pseudo-SCSI".
One feature of SCSI is a linear address space. There is no
notion of CHS (cylinder, head, sector). A lot of devices can
be fitted to use the SCSI style command structure, and the
drivers job is to make a shim between the hardware, and what
the system thinks is a SCSI device.
Ordinary disks take IRQ14 and IRQ15, and fixed blocks of I/O
addresses. If other storage devices come "late to the party",
there is no more room in the vanilla IDE world for them. Thus,
they end up being declared as SCSI devices, and the OS calls
them using a SCSICMD type structure.
When you download the Promise driver, look for the .INF file
in the install directory. There are some declaration strings
in the .INF file, and that can be what you are seeing in the
Device Manager.
