Incorrect identification of SCSI "processor device" with XPe

[Chris Tate]

Hi,

I have a SCSI subsystem that communicates with a Windows XPe as a SCSI
"processor device". When XPe boots, it finds my target as a disk drive and
I have determined with the use of a SCSI analyzer that XPe sends numerous
drive specific SCSI commands to it even though it is returning "processor
device" and not a "direct access device" (hard drive). Why does this
happen, and how can it be prevented?

As for specifics on my system, my target uses a Qlogic FAS366U SCSI
controller which will be set to 16-bit async mode in normal operation. The
SBC uses a Symbios SYM53C895 host bus controller. This problem does not
occur if I use Windows 98SE as the OS.

Thanks,

-Chris

Chris,

Before going any further, how the hardware behaves under XP Pro?
The main pattern is that if you can't get it working under XP Pro, you will unlikely have it working on XPe.

You may want to post your question to more appropriate XP programming NG.
