NAME
autoconf
- diagnostics from the autoconfiguration code
DESCRIPTION
When
UNIX
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
config(8)
and compiled into each kernel.
Autoconfiguration on the
HP300 s
is similar to that on the
VAX
the primary difference is in the naming conventions.
On the
HP300
if devices exist which are not configured they will be ignored;
if devices exist of unsupported type they will be ignored.
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
`rd0
'
if it exists.
If such a system is booted with the
RB_ASKNAME
option (see
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.
DIAGNOSTICS
- CPU type not configured.
-
You tried to boot
UNIX
on a
CPU
type which it doesn't
(or at least this compiled version of
UNIX
doesn't) understand.
- hpib%d at sc%d, ipl %d.
-
An
HP-IB
was found at sc%d (the select code)
with ipl%d (interrupt priority level).
UNIX
will call it hpib%d.
- %s%d: %s.
-
- %s%d at hpib%d, slave %d.
-
An
HP-IB
disk or tape controller was found.
For disks
`%s%d'
will look like
`rd0
'
for tapes like
`ct0
'
The
`%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.
- grf0 csr 0x560000
-
- 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.
- %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.
`%s'
will be one of
dca(4)
(single-port serial interfaces),
dcm(4)
(four-port serial interfaces), or
le(4)
( LAN
cards).
The slave number comes from the address select switches on the interface card.
