Kernel Driver Problem

Hello Listers!

I have a small problem with an icp scsi raid controller
and its drivers. ICP self tested the driver with FreeBSD
5.0-Release only, but i get only a "No such file or directory"
error - so i have the small hope that someone here can help
me to fix and take a look on the src code?

http://www.icp-vortex.com/ftp/download/rprd/freebsd/freebsd.zip
(location from the drivers i tryed to use).

Small note I installed 5.3-RELEASE and did src-sys update with
the following configuration:

*default host=cvsup5.FreeBSD.org
*default base=/var/db
*default prefix=/usr
*default release=cvs tag=RELENG_5_3
*default delete use-rel-suffix compress

src-sys

Here now the error i get:

B0X1# config B0X1
