hwinfo gives no output on this system.
dalton:~# hwinfo --framebuffer
dalton:~#        

What is needed to have a framebuffer?

Thanks,          ... Peter E.

That's a shot in the dark, but try booting with vga=788

Andrei & Richard,

ap> That's a shot in the dark, but try booting with vga=788

That also fails on the IBM NetVist machine.
But the machine at home gives sensible
output from "hwinfo --framebuffer".
I'll try qemu on it next weekend.

Thanks for the help,      ... Peter E.

Thanks.  I have a little progress.

On the Toshiba 4000 CDS this weekend,
"vga=788" gives a display.  

Also I found that a vga/vesa number which
is faulty, will prompt grub or the kernel
to display a list of configurations and
wait for a choice.

When the system prompt appears I can again try

qemu -m 40 -boot d -cdrom /home/peter/AosCD.iso

Some text from qemu flashes briefly on the
screen and then it grinds to a halt with
this message.

Could not open '/dev/kqemu' - QEMU acceleration layer not activated: No such file or directory
Could not open SDL display

I've installed the kqemu packages yet
/dev/kqemu is absent.

What is the problem with kqemu?

Thanks for any further ideas,
                     ... Peter E.

When I was using qemu I had this (now it's disabled, of course)

$ grep kqemu /etc/modprobe.d/00local
#options kqemu major=0

so /dev/kqemu gets created automatically

You will also have to list kqemu in /etc/modules to have it load on
every boot. Otherwise you will have to modprobe it by hand.

Andrei

Andrei,

ap> $ grep kqemu /etc/modprobe.d/00local
#options kqemu major=0
   ...
...list kqemu in /etc/modules ...

Good.  Thanks!  kqemu works now.

I still have this message about SDL.

newton:~# qemu -m 40 -hda /dev/sda -cdrom /home/peter/AosCD.iso -boot d
Could not open SDL display
newton:~#

libsdl1.2debian-all is installed but "man sdl"
and "man libsdl" yield nothing.  Any tips on
making SDL work?

Thanks,             ... Peter E.

I vaguely recall an issue with my mouse related to SDL (which is why I
eventually dropped qemu in favor of virtualbox-ose). Try the qemu docs.

Andrei
