The BusLogic FlashPoint SCSI Host Adapters are now fully supported on Linux.
The upgrade program described below has been officially terminated effective
31 March 1997 since it is no longer needed.


	  MYLEX INTRODUCES LINUX OPERATING SYSTEM SUPPORT FOR ITS
	      BUSLOGIC FLASHPOINT LINE OF SCSI HOST ADAPTERS


FREMONT, CA, -- October 8, 1996 -- Mylex Corporation has expanded Linux
operating system support to its BusLogic brand of FlashPoint Ultra SCSI
host adapters.  All of BusLogic's other SCSI host adapters, including the
MultiMaster line, currently support the Linux operating system.  Linux
drivers and information will be available on October 15th at
http://www.dandelion.com/Linux/.

"Mylex is committed to supporting the Linux community," says Peter Shambora,
vice president of marketing for Mylex.  "We have supported Linux driver
development and provided technical support for our host adapters for several
years, and are pleased to now make our FlashPoint products available to this
user base."

The Linux Operating System

Linux is a freely-distributed implementation of UNIX for Intel x86, Sun
SPARC, SGI MIPS, Motorola 68k, Digital Alpha AXP and Motorola PowerPC
machines.  It supports a wide range of software, including the X Window
System, Emacs, and TCP/IP networking.  Further information is available at
http://www.linux.org and http://www.ssc.com/linux.

FlashPoint Host Adapters

The FlashPoint family of Ultra SCSI host adapters, designed for workstation
and file server environments, are available in narrow, wide, dual channel,
and dual channel wide versions.  These adapters feature SeqEngine
automation technology, which minimizes SCSI command overhead and reduces
the number of interrupts generated to the CPU.

			       ANNOUNCEMENT
	       BusLogic FlashPoint LT/BT-948 Upgrade Program
			      1 February 1996

			  ADDITIONAL ANNOUNCEMENT
	       BusLogic FlashPoint LW/BT-958 Upgrade Program
			       14 June 1996

Ever since its introduction last October, the BusLogic FlashPoint LT has
been problematic for members of the Linux community, in that no Linux
drivers have been available for this new Ultra SCSI product.  Despite it's
officially being positioned as a desktop workstation product, and not being
particularly well suited for a high performance multitasking operating
system like Linux, the FlashPoint LT has been touted by computer system
vendors as the latest thing, and has been sold even on many of their high
end systems, to the exclusion of the older MultiMaster products.  This has
caused grief for many people who inadvertently purchased a system expecting
that all BusLogic SCSI Host Adapters were supported by Linux, only to
discover that the FlashPoint was not supported and would not be for quite
some time, if ever.

After this problem was identified, BusLogic contacted its major OEM
customers to make sure the BT-946C/956C MultiMaster cards would still be
made available, and that Linux users who mistakenly ordered systems with
the FlashPoint would be able to upgrade to the BT-946C.  While this helped
many purchasers of new systems, it was only a partial solution to the
overall problem of FlashPoint support for Linux users.  It did nothing to
assist the people who initially purchased a FlashPoint for a supported
operating system and then later decided to run Linux, or those who had
ended up with a FlashPoint LT, believing it was supported, and were unable
to return it.

In the middle of December, I asked to meet with BusLogic's senior
management to discuss the issues related to Linux and free software support
for the FlashPoint.  Rumors of varying accuracy had been circulating
publicly about BusLogic's attitude toward the Linux community, and I felt
it was best that these issues be addressed directly.  I sent an email
message after 11pm one evening, and the meeting took place the next
afternoon.  Unfortunately, corporate wheels sometimes grind slowly,
especially when a company is being acquired, and so it's taken until now
before the details were completely determined and a public statement could
be made.

BusLogic is not prepared at this time to release the information necessary
for third parties to write drivers for the FlashPoint.  The only existing
FlashPoint drivers have been written directly by BusLogic Engineering, and
there is no FlashPoint documentation sufficiently detailed to allow outside
developers to write a driver without substantial assistance.  While there
are people at BusLogic who would rather not release the details of the
FlashPoint architecture at all, that debate has not yet been settled either
way.  In any event, even if documentation were available today it would
take quite a while for a usable driver to be written, especially since I'm
not convinced that the effort required would be worthwhile.

However, BusLogic does remain committed to providing a high performance
SCSI solution for the Linux community, and does not want to see anyone left
unable to run Linux because they have a Flashpoint LT.  Therefore, BusLogic
has put in place a direct upgrade program to allow any Linux user worldwide
to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
SCSI Host Adapter.  The BT-948 is the Ultra SCSI successor to the BT-946C
and has all the best features of both the BT-946C and FlashPoint LT,
including smart termination and a flash PROM for easy firmware updates, and
is of course compatible with the present Linux driver.  The price for this
upgrade has been set at US $45 plus shipping and handling, and the upgrade
program will be administered through BusLogic Technical Support, which can
be reached by electronic mail at techsup@buslogic.com, by Voice at +1 408
654-0760, or by FAX at +1 408 492-1542.

As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
program has now been extended to encompass the FlashPoint LW Wide Ultra
SCSI Host Adapter.  Any Linux user worldwide may trade in their FlashPoint
LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter.  The
price for this upgrade has been set at US $65 plus shipping and handling.

I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
my BusLogic driver already included latent support for the BT-948/958.
Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
subsequent releases.  As a result of this cooperative testing process,
several firmware bugs were found and corrected.  My heavily loaded Linux
test system provided an ideal environment for testing error recovery
processes that are much more rarely exercised in production systems, but
are crucial to overall system stability.  It was especially convenient
being able to work directly with their firmware engineer in demonstrating
the problems under control of the firmware debugging environment; things
sure have come a long way since the last time I worked on firmware for an
embedded system.  I am presently working on some performance testing and
expect to have some data to report in the not too distant future.

BusLogic asked me to send this announcement since a large percentage of the
questions regarding support for the FlashPoint have either been sent to me
directly via email, or have appeared in the Linux newsgroups in which I
participate.  To summarize, BusLogic is offering Linux users an upgrade
from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
$45 plus shipping and handling, or from the unsupported FlashPoint LW
(BT-950) to the supported BT-958 for $65 plus shipping and handling.
