Subject: Part 15 of 22 /boot,/mdec,[T]MSCP updates
Index: /sys/<many>, /usr/src/etc/<several> 2.11BSD
Description:
Repeat-By:
Fix:
See part 0 (the README) for the Description, the Reason and
the instructions on how update your system.
This is part 15 of 22
The setup documentation was updated to reflect the fact that the
xp driver (in both the GENERIC kernel and standalone utilities)
prints the xptype address now. This prevents the use of obsolete/wrong
information from the hardcopy documents if the address changes due
to rebuilding the GENERIC kernel.

- The bootstrap can be forced to set up the machine for a different
- class of PDP-11 by placing an appropriate value in the console switch register
- (if there is one) while booting it.
- The value to use is the PDP-11 class, interpreted as an \fIoctal\fP number
- (use, for example, 070 for an 11/70).
- \fBWarning:\fP some old DEC bootstraps use the switch
- register to indicate where to boot from.
- On such machines, if the value in the switch register indicates
- an incorrect CPU, be sure to reset the switches immediately after
- initiating the tape bootstrap.

Check the drive type number in your controller manual,
or halt the CPU and examine this register.
If the value does not correspond to the actual drive type,
! you must place the correct value in the switch
! register after the tape bootstrap is running
! and before any attempt is made to access the drive.
This will override the drive type register.
This value must be present at the time each program
(including the bootstrap itself) first tries to access the disk.
! On machines without a switch register, the \fIxptype\fP
! variable can be patched in memory. After starting each utility
but before accessing the disk, halt the CPU, place the new drive type
! number at the proper memory location with the console switches or monitor,
! and then continue. The location of \fIxptype\fP in each utility is
! .\"CHECK - XXX
! mkfs: 034146, restor: 040054, icheck: 035002 and boot: 0634640
! (the location for boot is higher because it relocates itself).
Once UNIX itself is booted (see section ``\fBStep 4: booting UNIX\fP'') you must
! patch it also.
.PP
Finally, determine the proper interleaving factors \fIm\fP and \fIn\fP
for your disk and CPU combination from the following table.

\fBNote:\fP If you are booting from an \fIxp\fP with a drive type
that is not recognized, it will be necessary to patch the system before
it first accesses the root file system.
! Halt the processor after it
! has begun printing the version string but before it has finished printing
! the ``mem = ...'' strings.
Place the drive type number corresponding to your drive
! .\"CHECK - XXX
! at location 010622;
! the address for
! the first controller's CSR is 046552.
If you plan to use any drives other than 0 before you recompile

Make the patches and continue the CPU.
The value before patching must be zero. If it is not, you have halted too
late and should try again.

Place the drive type number corresponding to your drive

! high byte is the drive unit number.
! The address for the first controller's CSR is \fIxp_controller\fP plus 4.
! It should be noted that at present the kernel may only be booted from a
! controller at the standard/first CSR.
If you plan to use any drives other than 0 before you recompile
! the system, you should patch the location for those drives. The \fIxp_drive\fP
! structure in the \fBGENERIC\fP kernel is 012 bytes long.
Make the patches and continue the CPU.
The value before patching must be zero. If it is not, you have halted too
late and should try again.
