			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://sourceforge.net/projects/dandelion/.

			"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/.

			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.

			About Mylex
			===========

			Mylex Corporation (NASDAQ/NM SYMBOL: MYLX), founded in 1983, is a leading
			producer of RAID technology and network management products. The company
			produces high performance disk array (RAID) controllers, and complementary
			computer products for network servers, mass storage systems, workstations
			and system boards. Through its wide range of RAID controllers and its
			BusLogic line of Ultra SCSI host adapter products, Mylex provides enabling
			intelligent I/O technologies that increase network management control,
			enhance CPU utilization, optimize I/O performance, and ensure data security
			and availability. Products are sold globally through a network of OEMs,
			major distributors, VARs, and system integrators. Mylex Corporation is
			headquartered at 34551 Ardenwood Blvd., Fremont, CA.

			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 its
			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.
