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

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

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

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

This driver works *ONLY* for Future Domain cards using the TMC-1800,
|
|
TMC-18C50, or TMC-18C30 chip. This includes models TMC-1650, 1660, 1670,
|
|
and 1680. These are all 16-bit cards.
|
|
|
|
The following BIOS signature signatures are for boards which do *NOT*
|
|
work with this driver (these TMC-8xx and TMC-9xx boards may work with the
|
|
Seagate driver):
|
|
|
|
FUTURE DOMAIN CORP. (C) 1986-1988 V4.0I 03/16/88
|

|

|
(The cards which do *NOT* work are all 8-bit cards -- although some of
|
|
them have a 16-bit form-factor, the upper 8-bits are used only for IRQs
|
|
and are *NOT* used for data. You can tell the difference by following
|
|
the tracings on the circuit board -- if only the IRQ lines are involved,
|
|
you have a "8-bit" card, and should *NOT* use this driver.)

|

The RAM area starts at 0x1f00 from the bios_base address.
|

For BIOS Version 2.0:
|
|
|
|
The drive parameter table seems to start at 0x1f30.
|
|
The first byte's purpose is not known.
|
|
Next is the cylinder, head, and sector information.
|
|
The last 4 bytes appear to be the drive's size in sectors.
|
|
The other bytes in the drive parameter table are unknown.
|
|
If anyone figures them out, please send me mail, and I will
|
|
update these notes.
|
|
|
|
Tape drives do not get placed in this table.
|
|
|
|
There is another table at 0x1fea:
|
|
If the byte is 0x01, then the SCSI ID is not in use.
|
|
If the byte is 0x18 or 0x48, then the SCSI ID is in use,
|
|
although tapes don't seem to be in this table. I haven't
|
|
seen any other numbers (in a limited sample).
|
|
|
|
0x1f2d is a drive count (i.e., not including tapes)
|
|
|
|
The table at 0x1fcc are I/O ports addresses for the various
|
|
operations. I calculate these by hand in this driver code.
|
|
|
|
|
|
|
|
For the ISA-200S version of BIOS Version 2.0:
|
|
|
|
The drive parameter table starts at 0x1f33.
|
|
|
|
WARNING: Assume that the table entry is 25 bytes long. Someone needs
|
|
to check this for the Quantum ISA-200S card.
|
|
|
|
|
|
|
|
For BIOS Version 3.2:
|
|
|
|
The drive parameter table starts at 0x1f70. Each entry is
|
|
0x0a bytes long. Heads are one less than we need to report.

attention to the fields that are used by this algorithm -- it
|
|
only uses the absolute sector data. Recent versions of Linux's

fdisk(1) will fill this data in correctly, and forthcoming

versions will check for consistency.
|

Checking for a non-zero partition type is not part of the

Future Domain algorithm, but it seemed to be a reasonable thing

to do, especially in the Linux and BSD worlds. */
