-config IBMMCA_SCSI_ORDER_STANDARD
-	bool "Standard SCSI-order"
-	depends on SCSI_IBMMCA
-	---help---
-	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
-	  are assigned to the drive letters, starting with the lowest SCSI-id
-	  (physical number -- pun) to be drive C:, as seen from DOS and
-	  similar operating systems. When looking into papers describing the
-	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
-	  The SCSI-standard follows a hardware-hierarchy which says that id 7
-	  has the highest priority and id 0 the lowest. Therefore, the host
-	  adapters are still today everywhere placed as SCSI-id 7 by default.
-	  In the SCSI-standard, the drive letters express the priority of the
-	  disk. C: should be the hard disk, or a partition on it, with the
-	  highest priority. This must therefore be the disk with the highest
-	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
-	  original definition of the SCSI-standard as also industrial- and
-	  process-control-machines, like VME-CPUs running under realtime-OSes
-	  (e.g. LynxOS, OS9) do.
-
-	  If you like to run Linux on your MCA-machine with the same
-	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
-	  machine, which is in addition conformant to the SCSI-standard, you
-	  must say Y here. This is also necessary for MCA-Linux users who want
-	  to keep downward compatibility to older releases of the
-	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
-	  June 1997).
-
-	  If you like to have the lowest SCSI-id assigned as drive C:, as
-	  modern SCSI-BIOSes do, which does not conform to the standard, but
-	  is widespread and common in the PC-world of today, you must say N
-	  here. If unsure, say Y.

-config IBMMCA_SCSI_DEV_RESET
-	bool "Reset SCSI-devices at boottime"
-	depends on SCSI_IBMMCA
-	---help---
-	  By default, SCSI-devices are reset when the machine is powered on.
-	  However, some devices exist, like special-control-devices,
-	  SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
-	  not reset when switched on. If you say Y here, each device connected
-	  to your SCSI-bus will be issued a reset-command after it has been
-	  probed, while the kernel is booting. This may cause problems with
-	  more modern devices, like hard disks, which do not appreciate these
-	  reset commands, and can cause your system to hang. So say Y only if
-	  you know that one of your older devices needs it; N is the safe
-	  answer.

- *
- * FutureDomain MCS-600/700 v0.2 03/11/1998 by ZP Gu (zpg@castle.net)
- *
- * This driver is cloned from fdomain.* to specifically support
- * the Future Domain MCS 600/700 MCA SCSI adapters. Some PS/2s
- * also equipped with IBM Fast SCSI Adapter/A which is an OEM
- * of MCS 700.
- *
- * This driver also supports Reply SB16/SCSI card (the SCSI part).
- *
- * What makes this driver different is that this driver is MCA only
- * and it supports multiple adapters in the same system, IRQ 
- * sharing, some driver statistics, and maps highest SCSI id to sda.
- * All cards are auto-detected.
- *
- * Assumptions: TMC-1800/18C50/18C30, BIOS >= 3.4
- *
- * LILO command-line options:
- *   fd_mcs=<FIFO_COUNT>[,<FIFO_SIZE>]

- 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.
- [*****Now a runtime option*****]
-
- 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.
