NAME
autoconf —
diagnostics from the
autoconfiguration code
DESCRIPTION
When
NetBSD 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(1) and compiled into
each kernel.
Autoconfiguration on the HP300s 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 NetBSD on a CPU
type which it doesn't (or at least this compiled version of
NetBSD doesn't) understand.
- hpibbus%d at sc%d, ipl %d.
- An HP-IB was found at sc%d (the select code) with ipl%d
(interrupt priority level). NetBSD will call it
hpibbus%d.
- %s%d: %s.
- %s%d at hpibbus%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
com(4) (single-port serial
interfaces),
hp300/dcm(4)
(four-port serial interfaces), or
le(4) (LAN cards). The slave
number comes from the address select switches on the interface card.
