NetBSD/arm26 \*V should support all common Acorn machines fitted with
|
|
ARM2, ARM3 and ARM250 CPUs. This includes all Archimedes systems except
|
|
for the A500 and A680 prototypes, all R-series workstations, the BBC A3000,
|
|
the A5000, A4, A3010, A3020 and A4000.
|
|
.Pp
|
|
NetBSD/arm26 currently requires exactly eight megabytes of RAM to work.
|
|
Four-megabyte systems should work, but tend to run out of memory very easily.
|
|
.Pp
|
|
NetBSD/arm26 supports a subset of the on-board I/O systems on these machines.
|
|
The on-board video system is supported, as are the standard keyboard and
|
|
mouse. Other on-board device support differs between two classes of machine:
|
|
.Bl -tag -width 5em
|
|
.It "Old machines (Archimedes, R-series and BBC A3000)"
|
|
None of the other on-board devices are supported.
|
|
.It "New machines (A5000, A4, A3010, A3020 and A4000)"
|
|
The on-board IDE controller, serial port and parallel port are believed to
|
|
be supported, but this support is mostly untested.
|
|

|
|
NetBSD/arm26 supports a few Expansion Cards (otherwise known as "podules").
|
|
At present, the following are known to work:
|
|
.Bl -bullet
|
|
.It
|
|
Acorn AKA25 Ethernet (Ether1) (ei)
|
|
.It
|
|
Atomwide Ethernet III (Ether3) (ea)
|

|
|
NetBSD/arm26 uses the machine's ROM OS to boot, and hence depends slightly on
|
|
it. It's been tested with RISC OS 3.10 and RISC OS 3.11, and should work
|
|
with other versions of RISC OS as well. It hasn't been tested with Arthur at
|
|
all.
