[Hsiang-Yi Huang]

Here is what I got when I try to get data through SCSI card...what's
wrong???

What I try to do is writing a program which can pull some data and
information from a device through a SCSI card.  And the program works
fine for Solaris and Red Hat Linux but when I tried my program in
FreeBSD 4.6 and 5.1, I got this message.  What should I do???
