   4The BusLogic FlashPoint SCSI Driver
   7The BusLogic FlashPoint SCSI Host Adapters are now fully supported on Linux.
   8The upgrade program described below has been officially terminated effective
   931 March 1997 since it is no longer needed.
  17  FREMONT, CA, -- October 8, 1996 -- Mylex Corporation has expanded Linux
  18  operating system support to its BusLogic brand of FlashPoint Ultra SCSI
  19  host adapters.  All of BusLogic's other SCSI host adapters, including the
  20  MultiMaster line, currently support the Linux operating system.  Linux
  21  drivers and information will be available on October 15th at
  24  "Mylex is committed to supporting the Linux community," says Peter Shambora,
  25  vice president of marketing for Mylex.  "We have supported Linux driver
  26  development and provided technical support for our host adapters for several
  27  years, and are pleased to now make our FlashPoint products available to this
  28  user base."
  30The Linux Operating System
  33Linux is a freely-distributed implementation of UNIX for Intel x86, Sun
  34SPARC, SGI MIPS, Motorola 68k, Digital Alpha AXP and Motorola PowerPC
  35machines.  It supports a wide range of software, including the X Window
  36System, Emacs, and TCP/IP networking.  Further information is available at

  39FlashPoint Host Adapters
  42The FlashPoint family of Ultra SCSI host adapters, designed for workstation
  43and file server environments, are available in narrow, wide, dual channel,
  44and dual channel wide versions.  These adapters feature SeqEngine
  45automation technology, which minimizes SCSI command overhead and reduces
  46the number of interrupts generated to the CPU.

  78               BusLogic FlashPoint LT/BT-948 Upgrade Program
  79                              1 February 1996
  81                          ADDITIONAL ANNOUNCEMENT
  82               BusLogic FlashPoint LW/BT-958 Upgrade Program
  83                               14 June 1996
  85  Ever since its introduction last October, the BusLogic FlashPoint LT has
  86  been problematic for members of the Linux community, in that no Linux
  87  drivers have been available for this new Ultra SCSI product.  Despite its
  88  officially being positioned as a desktop workstation product, and not being
  89  particularly well suited for a high performance multitasking operating
  90  system like Linux, the FlashPoint LT has been touted by computer system
  91  vendors as the latest thing, and has been sold even on many of their high
  92  end systems, to the exclusion of the older MultiMaster products.  This has
  93  caused grief for many people who inadvertently purchased a system expecting
  94  that all BusLogic SCSI Host Adapters were supported by Linux, only to
  95  discover that the FlashPoint was not supported and would not be for quite
  96  some time, if ever.
  98  After this problem was identified, BusLogic contacted its major OEM
  99  customers to make sure the BT-946C/956C MultiMaster cards would still be
 100  made available, and that Linux users who mistakenly ordered systems with
 101  the FlashPoint would be able to upgrade to the BT-946C.  While this helped
 102  many purchasers of new systems, it was only a partial solution to the
 103  overall problem of FlashPoint support for Linux users.  It did nothing to
 104  assist the people who initially purchased a FlashPoint for a supported
 105  operating system and then later decided to run Linux, or those who had
 106  ended up with a FlashPoint LT, believing it was supported, and were unable
 107  to return it.
 109  In the middle of December, I asked to meet with BusLogic's senior
 110  management to discuss the issues related to Linux and free software support
 111  for the FlashPoint.  Rumors of varying accuracy had been circulating
 112  publicly about BusLogic's attitude toward the Linux community, and I felt
 113  it was best that these issues be addressed directly.  I sent an email
 114  message after 11pm one evening, and the meeting took place the next
 115  afternoon.  Unfortunately, corporate wheels sometimes grind slowly,
 116  especially when a company is being acquired, and so it's taken until now
 117  before the details were completely determined and a public statement could
 118  be made.
 120  BusLogic is not prepared at this time to release the information necessary
 121  for third parties to write drivers for the FlashPoint.  The only existing
 122  FlashPoint drivers have been written directly by BusLogic Engineering, and
 123  there is no FlashPoint documentation sufficiently detailed to allow outside
 124  developers to write a driver without substantial assistance.  While there
 125  are people at BusLogic who would rather not release the details of the
 126  FlashPoint architecture at all, that debate has not yet been settled either
 127  way.  In any event, even if documentation were available today it would
 128  take quite a while for a usable driver to be written, especially since I'm
 129  not convinced that the effort required would be worthwhile.
 131  However, BusLogic does remain committed to providing a high performance
 132  SCSI solution for the Linux community, and does not want to see anyone left
 133  unable to run Linux because they have a Flashpoint LT.  Therefore, BusLogic
 134  has put in place a direct upgrade program to allow any Linux user worldwide
 135  to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
 136  SCSI Host Adapter.  The BT-948 is the Ultra SCSI successor to the BT-946C
 137  and has all the best features of both the BT-946C and FlashPoint LT,
 138  including smart termination and a flash PROM for easy firmware updates, and
 139  is of course compatible with the present Linux driver.  The price for this
 140  upgrade has been set at US $45 plus shipping and handling, and the upgrade
 141  program will be administered through BusLogic Technical Support, which can
 142  be reached by electronic mail at, by Voice at +1 408
 143  654-0760, or by FAX at +1 408 492-1542.
 145  As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
 146  program has now been extended to encompass the FlashPoint LW Wide Ultra
 147  SCSI Host Adapter.  Any Linux user worldwide may trade in their FlashPoint
 148  LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter.  The
 149  price for this upgrade has been set at US $65 plus shipping and handling.
 151  I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
 152  my BusLogic driver already included latent support for the BT-948/958.
 153  Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
 154  subsequent releases.  As a result of this cooperative testing process,
 155  several firmware bugs were found and corrected.  My heavily loaded Linux
 156  test system provided an ideal environment for testing error recovery
 157  processes that are much more rarely exercised in production systems, but
 158  are crucial to overall system stability.  It was especially convenient
 159  being able to work directly with their firmware engineer in demonstrating
 160  the problems under control of the firmware debugging environment; things
 161  sure have come a long way since the last time I worked on firmware for an
 162  embedded system.  I am presently working on some performance testing and
 163  expect to have some data to report in the not too distant future.
 165  BusLogic asked me to send this announcement since a large percentage of the
 166  questions regarding support for the FlashPoint have either been sent to me
 167  directly via email, or have appeared in the Linux newsgroups in which I
 168  participate.  To summarize, BusLogic is offering Linux users an upgrade
 169  from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
 170  $45 plus shipping and handling, or from the unsupported FlashPoint LW
 171  (BT-950) to the supported BT-958 for $65 plus shipping and handling.
