SCSI OR PCI

 
What is the easiest or shortest way to tell if a harddisk is a PCI or 
SCSI
( or an  harddisk whose partition is given )  .(in kernel or user
mode),Any way.
Thanks,
Dan

Look in the registry under HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port n\Scsi Bus n\Initiator Id nnn. (substitute digits for n and nnn). If the nnn value is 255 it is IDE, if it is something smaller - usually 7, but I can imagine how it could be anything under 15 - it’ll be SCSI. My machine with dual IDE & dual SCSI shows SCSI port 0-3, each with SCSI bus 0. The first 2 are the IDE channels with initiator ID 255, and the second 2 the SCSI channels with initiator ID 7.

I don’t remember how to get from drives to devices but I know it’s been covered before on this group!

Andy.

Hi Andy and All,
Thanks A lot,
Do you no any way to corealaite this reg entrys with ‘harddisk0’ or ‘harddisk1’…etc. that way I can know if ‘harddisk0’ for example is a SCSI or IDE.
Thanks again,
Daniel.
