 24  SUMMARY:
 25 
 26  Future Domain BIOS versions supported for autodetect:
 27     2.0, 3.0, 3.2, 3.4 (1.0), 3.5 (2.0), 3.6, 3.61
 28  Chips are supported:
 29     TMC-1800, TMC-18C50, TMC-18C30, TMC-36C70
 30  Boards supported:
 31     Future Domain TMC-1650, TMC-1660, TMC-1670, TMC-1680, TMC-1610M/MER/MEX
 32     Future Domain TMC-3260 (PCI)
 33     Quantum ISA-200S, ISA-250MG
 34     Adaptec AHA-2920A (PCI) [BUT *NOT* AHA-2920C -- use aic7xxx instead]
 35     IBM ?
 36  LILO/INSMOD command-line options:
 37     fdomain=<PORT_BASE>,<IRQ>[,<ADAPTER_ID>]
 38 
 39 
 40     
 41  NOTE:
 42 
 43  The Adaptec AHA-2920C has an Adaptec AIC-7850 chip on it.
 44  Use the aic7xxx driver for this board.
 45        
 46  The Adaptec AHA-2920A has a Future Domain chip on it, so this is the right
 47  driver for that card.  Unfortunately, the boxes will probably just say
 48  "2920", so you'll have to look on the card for a Future Domain logo, or a
 49  letter after the 2920.

 53  THANKS:
 54 
 55  Thanks to Adaptec for providing PCI boards for testing.  This finally
 56  enabled me to test the PCI detection and correct it for PCI boards that do
 57  not have a BIOS at a standard ISA location.  For PCI boards, LILO/INSMOD
 58  command-line options should no longer be needed.  --RF 18Nov98

 62  DESCRIPTION:
 63  
 64  This is the Linux low-level SCSI driver for Future Domain TMC-1660/1680
 65  TMC-1650/1670, and TMC-3260 SCSI host adapters.  The 1650 and 1670 have a
 66  25-pin external connector, whereas the 1660 and 1680 have a SCSI-2 50-pin
 67  high-density external connector.  The 1670 and 1680 have floppy disk
 68  controllers built in.  The TMC-3260 is a PCI bus card.
 69 
 70  Future Domain's older boards are based on the TMC-1800 chip, and this
 71  driver was originally written for a TMC-1680 board with the TMC-1800 chip.
 72  More recently, boards are being produced with the TMC-18C50 and TMC-18C30
 73  chips.  The latest and greatest board may not work with this driver.  If
 74  you have to patch this driver so that it will recognize your board's BIOS
 75  signature, then the driver may fail to function after the board is
 76  detected.
 77 
 78  Please note that the drive ordering that Future Domain implemented in BIOS
 79  versions 3.4 and 3.5 is the opposite of the order (currently) used by the
 80  rest of the SCSI industry.  If you have BIOS version 3.4 or 3.5, and have
 81  more than one drive, then the drive ordering will be the reverse of that
 82  which you see under DOS.  For example, under DOS SCSI ID 0 will be D: and
 83  SCSI ID 1 will be C: (the boot device).  Under Linux, SCSI ID 0 will be
 84  /dev/sda and SCSI ID 1 will be /dev/sdb.  The Linux ordering is consistent
 85  with that provided by all the other SCSI drivers for Linux.  If you want
 86  this changed, you will probably have to patch the higher level SCSI code.
 87  If you do so, please send me patches that are protected by #ifdefs.
 88 
 89  If you have a TMC-8xx or TMC-9xx board, then this is not the driver for
 90  your board.  Please refer to the Seagate driver for more information and
 91  possible support.

167  NOTES ON REFERENCES:
168 
169  The Maxtor manuals were free.  Maxtor telephone technical support is
170  great!
171 
172  The Future Domain manuals were $25 and $35.  They document the chip, not
173  the TMC-16x0 boards, so some information I had to guess at.  In 1992,
174  Future Domain sold DOS BIOS source for $250 and the UN*X driver source was
175  $750, but these required a non-disclosure agreement, so even if I could
176  have afforded them, they would *not* have been useful for writing this
177  publicly distributable driver.  Future Domain technical support has
178  provided some information on the phone and have sent a few useful FAXs.
179  They have been much more helpful since they started to recognize that the
180  word "Linux" refers to an operating system :-).
181 
182  
183 
184  ALPHA TESTERS:
185 
186  There are many other alpha testers that come and go as the driver
187  develops.  The people listed here were most helpful in times of greatest
188  need (mostly early on -- I've probably left out a few worthy people in
189  more recent times):
190 
191  Todd Carrico (todd@wutc.wustl.edu), Dan Poirier (poirier@cs.unc.edu ), Ken
192  Corey (kenc@sol.acs.unt.edu), C. de Bruin (bruin@bruin@sterbbs.nl), Sakari
193  Aaltonen (sakaria@vipunen.hit.fi), John Rice (rice@xanth.cs.odu.edu), Brad
194  Yearwood (brad@optilink.com), and Ray Toy (toy@soho.crd.ge.com).
195 
196  Special thanks to Tien-Wan Yang (twyang@cs.uh.edu), who graciously lent me
197  his 18C50-based card for debugging.  He is the sole reason that this
198  driver works with the 18C50 chip.
199 
200  Thanks to Dave Newman (dnewman@crl.com) for providing initial patches for
201  the version 3.4 BIOS.
202 
203  Thanks to James T. McKinley (mckinley@msupa.pa.msu.edu) for providing
204  patches that support the TMC-3260, a PCI bus card with the 36C70 chip.
205  The 36C70 chip appears to be "completely compatible" with the 18C30 chip.
206 
207  Thanks to Eric Kasten (tigger@petroglyph.cl.msu.edu) for providing the
208  patch for the version 3.5 BIOS.
209 
210  Thanks for Stephen Henson (shenson@nyx10.cs.du.edu) for providing the
211  patch for the Quantum ISA-200S SCSI adapter.
212  
213  Thanks to Adam Bowen for the signature to the 1610M/MER/MEX scsi cards, to
214  Martin Andrews (andrewm@ccfadm.eeg.ccf.org) for the signature to some
215  random TMC-1680 repackaged by IBM; and to Mintak Ng (mintak@panix.com) for
216  the version 3.61 BIOS signature.
217 
218  Thanks for Mark Singer (elf@netcom.com) and Richard Simpson
219  (rsimpson@ewrcsdra.demon.co.uk) for more Quantum signatures and detective
220  work on the Quantum RAM layout.
221 
222  Special thanks to James T. McKinley (mckinley@msupa.pa.msu.edu) for
223  providing patches for proper PCI BIOS32-mediated detection of the TMC-3260
224  card (a PCI bus card with the 36C70 chip).  Please send James PCI-related
225  bug reports.
226 
227  Thanks to Tom Cavin (tec@usa1.com) for preliminary command-line option
228  patches.
229 
230  New PCI detection code written by Martin Mares <mj@atrey.karlin.mff.cuni.cz>
231 
232  Insmod parameter code based on patches from Daniel Graham
233  <graham@balance.uoregon.edu>. 
234  
235  All of the alpha testers deserve much thanks.
236 
237 
238 
239  NOTES ON USER DEFINABLE OPTIONS:
240 
241  DEBUG: This turns on the printing of various debug information.
242 
243  ENABLE_PARITY: This turns on SCSI parity checking.  With the current
244  driver, all attached devices must support SCSI parity.  If none of your
245  devices support parity, then you can probably get the driver to work by
246  turning this option off.  I have no way of testing this, however, and it
247  would appear that no one ever uses this option.
248 
249  FIFO_COUNT: The host adapter has an 8K cache (host adapters based on the
250  18C30 chip have a 2k cache).  When this many 512 byte blocks are filled by
251  the SCSI device, an interrupt will be raised.  Therefore, this could be as
252  low as 0, or as high as 16.  Note, however, that values which are too high
253  or too low seem to prevent any interrupts from occurring, and thereby lock
254  up the machine.  I have found that 2 is a good number, but throughput may
255  be increased by changing this value to values which are close to 2.
256  Please let me know if you try any different values.
257 
258  RESELECTION: This is no longer an option, since I gave up trying to
259  implement it in version 4.x of this driver.  It did not improve
260  performance at all and made the driver unstable (because I never found one
261  of the two race conditions which were introduced by the multiple
262  outstanding command code).  The instability seems a very high price to pay
263  just so that you don't have to wait for the tape to rewind.  If you want
264  this feature implemented, send me patches.  I'll be happy to send a copy
265  of my (broken) driver to anyone who would like to see a copy.

447   and 1680.  These are all 16-bit cards.
448 
449   The following BIOS signature signatures are for boards which do *NOT*
450   work with this driver (these TMC-8xx and TMC-9xx boards may work with the
451   Seagate driver):

463   and are *NOT* used for data.  You can tell the difference by following
464   the tracings on the circuit board -- if only the IRQ lines are involved,

1605       
1606       The drive parameter table seems to start at 0x1f30.
1607       The first byte's purpose is not known.
1608       Next is the cylinder, head, and sector information.
1609       The last 4 bytes appear to be the drive's size in sectors.
1610       The other bytes in the drive parameter table are unknown.
1611       If anyone figures them out, please send me mail, and I will
1612       update these notes.
1613 
1614       Tape drives do not get placed in this table.
1615 
1616       There is another table at 0x1fea:
1617       If the byte is 0x01, then the SCSI ID is not in use.
1618       If the byte is 0x18 or 0x48, then the SCSI ID is in use,
1619       although tapes don't seem to be in this table.  I haven't
1620       seen any other numbers (in a limited sample).
1621 
1622       0x1f2d is a drive count (i.e., not including tapes)
1623 
1624       The table at 0x1fcc are I/O ports addresses for the various
1625       operations.  I calculate these by hand in this driver code.
1626

1629       For the ISA-200S version of BIOS Version 2.0:

1700             1) the first partition table is in use,
1701             2) the data in the first entry is correct, and
1702             3) partitions never divide cylinders
1703 
1704             Note that (1) may be FALSE for NetBSD (and other BSD flavors),
1705             as well as for Linux.  Note also, that Linux doesn't pay any
1706             attention to the fields that are used by this algorithm -- it
1707             only uses the absolute sector data.  Recent versions of Linux's
1708             fdisk(1) will fill this data in correctly, and forthcoming
1709             versions will check for consistency.
1710 
1711             Checking for a non-zero partition type is not part of the
1712             Future Domain algorithm, but it seemed to be a reasonable thing
1713             to do, especially in the Linux and BSD worlds. */
