I just recently got a SIIG UltraWide card, which uses the same chipset as
the Initio board you mention. It works pretty well for the most part,
though the SCSI bus occasionally hangs when doing certain tape
operations. The Initio web site has several Linux-related files,
including install files for Red Hat and SuSE, IIRC, though I've also seen
posts to the effect that these images may only work for installing Linux
to /dev/sda1. It shouldn't be too hard to create a more flexible install
routine, though; I've an outline of what's required to modify a standard
Red Hat install disk at http://www.users.fast.net/~rodsmith/rhjol.html.
Of course, this assumes you've got access to a working Red Hat system,
which could be a Catch-22.
The driver source I've seen (and which includes one precompiled binary)
also includes a text file describing in English how to incorporate the
drivers into the kernel. I've also seen descriptions of a regular kernel
patch file from Initio, but I've not actually seen this. I get the
impression that Initio's got multiple Linux driver files on their site
and/or has recently updated their files.
I've seen some discussion and contradictory claims about the legal status
of the Initio drivers, so I wrote to them to ask about this, as well as to
thank them for producing the drivers and to report the problems I'd had
with certain tape-related operations. Here's their reply, which sounds
like they intend to do the Right Thing:
: Yes we will be releasing our drivers and source code to the public, but
: first we have some issues to clean up with the drivers.
: The issue you noted in paragraph 3 may be just one of those issues. We
: do have problems with error recovery and slow devices.
: Please bear in mind that we are working on these issues and hope to have
: everything finished soon.
I just hope that "soon" is measured on typical computer product
timescales, as opposed to geological timescales. ;-)
Anyhow, I think Initio does deserve praise for writing these drivers,
particularly if they get them included into the main Linux kernel in a
timely manner. (It's probably too late for kernel 2.2, sadly.)
