[-- Attachment #1 --] Hi, I'm planning on writing a driver for a very large and slow Storage Media, but don't know how to interface the directory listings to the FreeBSD OS. I wonder if someone can point me in the right direction, on how to start writing this software? The driver I'm trying to write is one that will implore (for now) the SCSI bus, where the data comes in from the large Storage Device, and also one of the serial buses (com ports); to stear a rather complicated PIC-regulated device. My problem is that, I need to get an enormous list of files and directories, into my FreeBSD server's file system, so that the server sees the _extra_files_ as if they were mounted onto the existing set of drives; so as to be able to add " an enormous new drive in the /etc/fstab file". The reason why I want to use a serial port in conjunction with the SCSI-2 interface is mainly because I know very little about the SCSI-protocol's serious stuff, AND, that this Storage Device is so large (around the Tera Byte region), that I doubt the SCSI-2 interface supports such a large addressing scheme. I'm almost sure this qualifies as a form of database programming, but so far I've only done minor programming of such nature. Unfortunately, when it comes to the interfacing between the device I'm making, and the FreeBSD OS, I don't even know where to start. I'm plannig on writing it in C-language (in case you'd like to know). My field of expertise is not very much of a software nature, so please be kind with the complication of your reply - if any :-)) . Thank you in advance, Nader S.
