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.

462 them have a 16-bit form-factor, the upper 8-bits are used only for IRQs
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,
465 you have a "8-bit" card, and should *NOT* use this driver.)

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:
1630
1631 The drive parameter table starts at 0x1f33.
1632
1633 WARNING: Assume that the table entry is 25 bytes long. Someone needs
1634 to check this for the Quantum ISA-200S card.
1635
1636
1637
1638 For BIOS Version 3.2:
1639
1640 The drive parameter table starts at 0x1f70. Each entry is
1641 0x0a bytes long. Heads are one less than we need to report.

1707 only uses the absolute sector data. Recent versions of Linux's
