| 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 | |

| 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. | |
| Contact BusLogic Technical Support at techsup@buslogic.com or +1 408 | |
| 654-0760 to take advantage of their offer. | |
