scsi: delete the MCA specific drivers and driver code
The support for CONFIG_MCA is being removed, since the 20 year old hardware simply isn't capable of meeting today's software demands on CPU and memory resources. This commit removes the MCA specific SCSI drivers, and the MCA specific portions of code in dual role ISA/MCA drivers. Also, the MCA specific SCSI documentation is removed.

|

If the adapter isn't found during boot (a common problem for models

56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel

if that doesn't work check your reference diskette). Owners of

model 95 with a LED-matrix-display can in addition activate some

activity info like under OS/2, but more informative, by setting
|

'ibmmcascsi=display' as an additional kernel parameter. Try "man

bootparam" or see the documentation of your boot loader about how to
|

pass options to the kernel.

---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.

|

---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.
