man scsi-config

DESCRIPTION
scsi-config queries information from an scsi target with a nice Tcl/Tk
user interface. If you do not specify a device to query, scsi-config
calculates a list of available devices and prompts it to you.

I don't believe it since I've never heard that before.
I'd like to see the specific reference if you can find it.

Follow the guidelines Carlos posted...or read the "Build a Kernel"
off the main www.parisc-linux.org homepage:
http://www.parisc-linux.org/kernel/index.html
If that page needs updating, it's in our CVS "web" (vs linux-2.4) repository.
I'll gladly take patches for that too.
