1 The BusLogic FlashPoint SCSI Host Adapters are now fully supported on Linux. 2 The upgrade program described below has been officially terminated effective 3 31 March 1997 since it is no longer needed. 4 5 6 7 MYLEX INTRODUCES LINUX OPERATING SYSTEM SUPPORT FOR ITS 8 BUSLOGIC FLASHPOINT LINE OF SCSI HOST ADAPTERS 9 10 11 FREMONT, CA, -- October 8, 1996 -- Mylex Corporation has expanded Linux 12 operating system support to its BusLogic brand of FlashPoint Ultra SCSI 13 host adapters. All of BusLogic's other SCSI host adapters, including the 14 MultiMaster line, currently support the Linux operating system. Linux 15 drivers and information will be available on October 15th at 16 http://sourceforge.net/projects/dandelion/. 17 18 "Mylex is committed to supporting the Linux community," says Peter Shambora, 19 vice president of marketing for Mylex. "We have supported Linux driver 20 development and provided technical support for our host adapters for several 21 years, and are pleased to now make our FlashPoint products available to this 22 user base." 23 24 The Linux Operating System 25 26 Linux is a freely-distributed implementation of UNIX for Intel x86, Sun 27 SPARC, SGI MIPS, Motorola 68k, Digital Alpha AXP and Motorola PowerPC 28 machines. It supports a wide range of software, including the X Window 29 System, Emacs, and TCP/IP networking. Further information is available at 30 http://www.linux.org and http://www.ssc.com/. 31 32 FlashPoint Host Adapters 33 34 The FlashPoint family of Ultra SCSI host adapters, designed for workstation 35 and file server environments, are available in narrow, wide, dual channel, 36 and dual channel wide versions. These adapters feature SeqEngine 37 automation technology, which minimizes SCSI command overhead and reduces 38 the number of interrupts generated to the CPU. 39 40 About Mylex 41 42 Mylex Corporation (NASDAQ/NM SYMBOL: MYLX), founded in 1983, is a leading 43 producer of RAID technology and network management products. The company 44 produces high performance disk array (RAID) controllers, and complementary 45 computer products for network servers, mass storage systems, workstations 46 and system boards. Through its wide range of RAID controllers and its 47 BusLogic line of Ultra SCSI host adapter products, Mylex provides enabling 48 intelligent I/O technologies that increase network management control, 49 enhance CPU utilization, optimize I/O performance, and ensure data security 50 and availability.

Despite its 75 officially being positioned as a desktop workstation product, and not being 76 particularly well suited for a high performance multitasking operating 77 system like Linux, the FlashPoint LT has been touted by computer system 78 vendors as the latest thing, and has been sold even on many of their high 79 end systems, to the exclusion of the older MultiMaster products. This has 80 caused grief for many people who inadvertently purchased a system expecting 81 that all BusLogic SCSI Host Adapters were supported by Linux, only to 82 discover that the FlashPoint was not supported and would not be for quite 83 some time, if ever. 84 85 After this problem was identified, BusLogic contacted its major OEM 86 customers to make sure the BT-946C/956C MultiMaster cards would still be 87 made available, and that Linux users who mistakenly ordered systems with 88 the FlashPoint would be able to upgrade to the BT-946C. While this helped 89 many purchasers of new systems, it was only a partial solution to the 90 overall problem of FlashPoint support for Linux users. It did nothing to 91 assist the people who initially purchased a FlashPoint for a supported 92 operating system and then later decided to run Linux, or those who had 93 ended up with a FlashPoint LT, believing it was supported, and were unable 94 to return it. 95 96 In the middle of December, I asked to meet with BusLogic's senior 97 management to discuss the issues related to Linux and free software support 98 for the FlashPoint. Rumors of varying accuracy had been circulating 99 publicly about BusLogic's attitude toward the Linux community, and I felt 100 it was best that these issues be addressed directly. I sent an email 101 message after 11pm one evening, and the meeting took place the next 102 afternoon. Unfortunately, corporate wheels sometimes grind slowly, 103 especially when a company is being acquired, and so it's taken until now 104 before the details were completely determined and a public statement could 105 be made. 106 107 BusLogic is not prepared at this time to release the information necessary 108 for third parties to write drivers for the FlashPoint. The only existing 109 FlashPoint drivers have been written directly by BusLogic Engineering, and 110 there is no FlashPoint documentation sufficiently detailed to allow outside 111 developers to write a driver without substantial assistance. While there 112 are people at BusLogic who would rather not release the details of the 113 FlashPoint architecture at all, that debate has not yet been settled either 114 way. In any event, even if documentation were available today it would 115 take quite a while for a usable driver to be written, especially since I'm 116 not convinced that the effort required would be worthwhile. 117 118 However, BusLogic does remain committed to providing a high performance 119 SCSI solution for the Linux community, and does not want to see anyone left 120 unable to run Linux because they have a Flashpoint LT. Therefore, BusLogic 121 has put in place a direct upgrade program to allow any Linux user worldwide 122 to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra 123 SCSI Host Adapter. The BT-948 is the Ultra SCSI successor to the BT-946C 124 and has all the best features of both the BT-946C and FlashPoint LT, 125 including smart termination and a flash PROM for easy firmware updates, and 126 is of course compatible with the present Linux driver. The price for this 127 upgrade has been set at US $45 plus shipping and handling, and the upgrade 128 program will be administered through BusLogic Technical Support, which can 129 be reached by electronic mail at firstname.lastname@example.org, by Voice at +1 408 130 654-0760, or by FAX at +1 408 492-1542. 131 132 As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade 133 program has now been extended to encompass the FlashPoint LW Wide Ultra 134 SCSI Host Adapter. Any Linux user worldwide may trade in their FlashPoint 135 LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter. The 136 price for this upgrade has been set at US $65 plus shipping and handling. 137 138 I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of 139 my BusLogic driver already included latent support for the BT-948/958. 140 Additional cosmetic support for the Ultra SCSI MultiMaster cards was added 141 subsequent releases. As a result of this cooperative testing process, 142 several firmware bugs were found and corrected. My heavily loaded Linux 143 test system provided an ideal environment for testing error recovery 144 processes that are much more rarely exercised in production systems, but 145 are crucial to overall system stability. It was especially convenient 146 being able to work directly with their firmware engineer in demonstrating 147 the problems under control of the firmware debugging environment; things 148 sure have come a long way since the last time I worked on firmware for an 149 embedded system. I am presently working on some performance testing and 150 expect to have some data to report in the not too distant future. 151 152 BusLogic asked me to send this announcement since a large percentage of the 153 questions regarding support for the FlashPoint have either been sent to me 154 directly via email, or have appeared in the Linux newsgroups in which I 155 participate. To summarize, BusLogic is offering Linux users an upgrade 156 from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US 157 $45 plus shipping and handling, or from the unsupported FlashPoint LW 158 (BT-950) to the supported BT-958 for $65 plus shipping and handling. 159 Contact BusLogic Technical Support at email@example.com or +1 408 160 654-0760 to take advantage of their offer. 161 162 Leonard N.
