[Qemu-devel] [PATCH] [MIPS] Acer Pica 61 machine

[Hervé Poussineau]

[-- Attachment #1: Type: text/plain, Size: 466 bytes --]

Hi,

This patch adds a Acer Pica 61 machine emulation to Qemu. I based my work on
http://www.sensi.org/~alec/mips/acer_pica.html
This machine can be used with the firmwares available at
http://hpoussineau.free.fr/qemu/firmware (the PICA 61 versions).

I've tested NetBSD 1.5.1, NetBSD 1.6.2, OpenBSD 2.3 and MS Windows NT 3.51,
which start to boot, but all show different problems.
The *BSD images are available at http://hpoussineau.free.fr/qemu

Hervé

[Natalia Portillo]

How is it suppossed to boot?

It does not shows anything on screen, even it lacks a VGA output with
default command line.
