So, I cvs update'd today and there is a fair bit of progress with amd64
userspace. Unfortunately the kernel crashes fairly quickly.
I haven't had time to look into this, just thought I'd put this up in case
anyone else is looking at things.

I decided to share my experience as well...
I've tried installing the WinXP 64-bit preview under QEMU/x64 on Win32.
At first I had to add a little hack - hardcoded ACPI table - to enable
the setup loader to recognize the local APIC. After this the setup
starts loading the kernel and device drivers, everything works well
until it tries to jump to the loaded kernel. It crashes fairly quicky
and ends-up in endless exception loop, because the in-memory kernel
image is corrupted. The setup loader itself decompressed the image from
CAB/LZX file stored on a CD-ROM so it's pretty hard to find where's the
error and I've had no success at debugging it yet. ;-(
(See an example of the image corruption below.)
I would appreciate any suggestions on how to debug it/where the problem
can be.
Regards,
Filip

A long shot: I recently sent a patch to this list that fixed
installation of win98 from cdrom, the bug was that register DL was
modified during bios calls. The bug only occured when booting from
cdrom. So if you boot from cdrom and use an old bios version I
encourage you to upgrade rombios.c to rev 1.128 and see if that helps.

I've applied your patch, rebuilt the Bochs BIOS and it still doesn't
work. :-(
Anyway, thanks for suggestion,
Filip

Is this change committed to CVS or if not may I ask to see it? Bochs has
the same problem as my CVS qemu and (at least according to their mailing
list) they are stumped about how to get around this issue.
If you were able to get past that hurdle, maybe both teams can learn
something from this experience.
Thanks,
