[Qemu-devel] Knoppix boot attempt fails - "BIOS panic in rombios.c, line 1558"

[Chad Page]

	Just checked out qemu cvs (I was thinking of adding cd-rom support
this week, and it shows up this morning :) ) and I fed it Knoppix 9/24 and
I got that - More info as I get time to look at it.

I get failures like this as well using -boot c, though -boot d works.
What do the c and d stand for? I had assumed (presumably incorrectly)
that c=CD and d=disk.

I got the KNOPPIX_V3.2-2003-05-20 ISO to boot, though it fails early in
the boot process saying that it can't find the knoppix partition. The
lnx-bbc rescue CD (version 2.1) seemed to boot properly, but it
segfaulted in the later stages of the boot process.

I also tried a self-built OpenBSD 3.4 CD, though it complains relatively
early in the boot process that it can't find /dev/console. I've got a
few versions of Windows kicking around too - I'll give them a shot
shortly.

Thanks
Leigh

I should have commited the documentation :-) c = hard disk and d = 
CD-ROM (and someday a = floppy).

Do you try qemu-fast or qemu ? Can you record a log of the boot process 
  (at least a screen shot) ?

I have almost finished the task switch emulation (this is the last 
painful x86 emulation code). Once it is commited, Windows support will 
become possible.

This was using qemu - I took a couple of screenshots, which show the two
pages of output that I got when booting the OpenBSD CD:

http://gir.eclinic.com.au/~lsd/qemu/obsd/obsd-boot-2.png

I have to say that I haven't actually tested my OpenBSD ISO on a real
machine, and it does fail to boot properly on bochs as well (though much
later in the boot sequence). It does work on Virtual PC on my Powerbook
though, so I _think_ it's okay.

That's great to hear :) Just for a laugh, I tried booting a Windows 98
CD, which effectively means booting MS-DOS, and after the initial boot
menu screens (selecing whether to boot from hdd or CD, and what mode to
boot the CD in) I got a lot of:

qemu: unsupported keyboard cmd=0xff

messages in my terminal, and then qemu segfaulted.

if you type f8 and keep himem.sys form loading then you get up clearly! :-)

And what suirprise:
	Wenn you reboot (ctrl+alt+remove) after get up a dos boot disk you do not 
	need to remove the himem.sys. (but still not working.)

CD -Support broken?
	I can boot nearly every Boot-Cd i have tryed (Knoppix, Debian-Install, Suse, 
Windows98, Dos-BootCD, NowelDos-BootCD).
	But after booting the Bootimage on CD they all faild to find the CD Device 
for loading/mounting.
