[Qemu-devel] OS/2 lockups during bootup

[Nathan Kunkee]

Johannes,
Over this last weekend, I was able to install and boot OS/2 (v3, blue spine) 
through the latest CVS version of CVS. I encountered two problems: After 
copying the last base disk (6 I believe), the installer asked that I eject 
the disk and press enter. Somehow in the process of switching to the monitor 
and back, I could never get that last enter pressed. It turns out that there 
was nothing after that; all the needed files had been copied. The other 
issue I found was even though I had a blank disk image file, OS/2 did not 
install a master boot record. I had to boot with a Win 95 boot disk to add 
one. (fdisk /mbr)  I do see  CPU spike and fall during the load of 
IBM1S506.ADD.

For the rest of the list, I have not had any success with loading sound 
support. I'm using Win XP as a host.. Any thoughts?

Hope that helps, and thanks in advance.....
Nathan

Hi everybody,

I'm having some trouble booting up OS/2 in qemu (CVS, Linux host). OS/2
frequently hangs during bootup when loading one of the following device
drivers:
        IBM1FLPY.ADD
        IBM1S506.ADD
        IBMIDECD.FLT
        IBMDASD.DMD

The lockup may occur randonmly in any of these drivers or not at all. When
I reboot OS/2 or restart qemu a couple of times, I usually get past these
drivers eventually. It takes patience though.

I know that something has gone wrong when qemu starts using 99% of CPU
time while loading these drivers. I assume the drivers are in some kind of
loop waiting for some event to happen - I guess it's a timing problem and
sometimes things don't happen in the right sequence.

Any hints?

Thanks
        Johannes
