Qemu doesn't crash or freeze. But I can just ty= pe a single character and the nothing else. But the system is still running (there is a clock at the bottom right of the screen).

Y= ou can help debug the issue so it can be fixed in SeaBIOS. Start
w= ith producing a log from SeaBIOS by adding (on a recent qemu) the
following to the command-line:

-chardev stdio,id=3Dseabios -= device isa-debugcon,iobase=3D0x402,chardev=3Dseabios

Also, if there = is an image available for download, other developers

Are you running qemu 1.0 or latest from git? qemu 1.0 has seabios from commit 8e301472e324, I don't get the problem with this one. But latest qemu from git has seabios 1.6.3.1, it's with that version that I get my problem. Using latest seabios makes it go away, didn't try re-building 1.6.3.1 thoug= h.

I still ha= ve the problem with :

seabios git : c5c488f46b (it s= hoes a version pre-1.6.4-20120308_165857)

qemu g= it : 1c8a881daa (v1.0)

I also tried with latest qemu= from git : e326050 (snapshot from the git.qemu.org)

And it doesn't work for me.

Have you tried my disk = image ?

It doesn't crash= . I can just type a character, which prints on the screen, and then nothing= .

Maybe I made something= wrong...

Thanks,

Alain

But the system is still running (there is a > clock at the bottom right of the screen). I tracked this down. Looks like the image takes over the PS2 irq and keyboard handling, but then occasionally calls into the BIOS. When it does call the BIOS irq handler (manually), it expects the irq handler to enable the keyboard. Weird. Anyway, the patch below fixes it for me. -Kevin >>From 90ce89f8953da0e89c311aa34116b59aac1c6c5e Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Sun, 11 Mar 2012 20:45:56 -0400 Subject: [PATCH] ps2: Enable keyboard at end of PS2 port irq. To: seabios@seabios.org Looks like some old programs expect the keyboard irq to enable the keyboard port at the end of the irq. This behavior was seen on an image of "Concurrent DOS".
