.Dt AUTOCONF 4 hp300
|
|
.Os
|
|
.Sh NAME
|
|
.Nm autoconf
|
|
.Nd diagnostics from the autoconfiguration code
|
|
.Sh DESCRIPTION
|
|
When
|
|
.Nx
|
|
bootstraps it probes the innards of the machine
|
|
on which it is running
|
|
and locates controllers, drives, and other devices, printing out
|
|
what it finds on the console. This procedure is driven by a system
|
|
configuration table which is processed by
|
|
.Xr config 8
|
|
and compiled into each kernel.
|
|
.Pp
|
|
Autoconfiguration on the
|
|
.Tn HP300 Ns s
|
|
is similar to that on the
|
|
.Tn VAX ,
|
|
the primary difference is in the naming conventions.
|
|
On the
|
|
.Tn HP300 ,
|
|
if devices exist which are not configured they will be ignored;
|
|
if devices exist of unsupported type they will be ignored.
|
|
.Pp
|
|
Normally, the system uses the disk from which it was loaded as the root
|
|
filesystem.
|
|
If that is not possible,
|
|
a generic system will use
|
|
.Sq Li rd0
|
|
if it exists.
|
|
If such a system is booted with the
|
|
.Dv RB_ASKNAME
|
|
option (see
|
|
.Xr reboot 2 ) ,
|
|
then the name of the root device is read from the console terminal at boot
|
|
time, and any available device may be used.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It CPU type not configured.
|
|
You tried to boot
|
|
.Nx
|
|
on a
|
|
.Tn CPU
|
|
type which it doesn't
|
|
(or at least this compiled version of
|
|
.Nx
|
|
doesn't) understand.
|
|
.Pp
|
|
.It hpib%d at sc%d, ipl %d.
|
|
An
|
|
.Tn HP-IB
|
|
was found at sc%d (the select code)
|
|
with ipl%d (interrupt priority level).
|
|
.Nx
|
|
will call it hpib%d.
|
|
.Pp
|
|
.It %s%d: %s.
|
|
.It %s%d at hpib%d, slave %d.
|
|
An
|
|
.Tn HP-IB
|
|
disk or tape controller was found.
|
|
For disks
|
|
.Ql %s%d
|
|
will look like
|
|
.Sq Li rd0 ,
|
|
for tapes like
|
|
.Sq Li ct0 .
|
|
The
|
|
.Ql %s
|
|
in the first line will be a product type like ``7945A'' or ``9144''.
|
|
The slave number comes from the address select switches on the drive.
|
|
.Pp
|
|
.It grf0 csr 0x560000
|
|
.It grf%d at sc%d
|
|
A bit mapped display was found either at the ``internal'' address (first case)
|
|
or at some ``external'' select code (second case).
|
|
If it exists, the internal display will always be unit 0.
|
|
.Pp
|
|
.It %s%d at sc%d, ipl %d flags %d
|
|
Another peripheral controller was found at the indicated select code
|
|
and with indicated interrupt priority level.
|
|
.Ql %s
|
|
will be one of
|
|
.Xr dca 4
|
|
(single-port serial interfaces),
|
|
.Xr dcm 4
|
|
(four-port serial interfaces), or
|
|
.Xr le 4
|
|
.Pf ( Tn LAN
|
|
cards).
|
|
The slave number comes from the address select switches on the interface card.
