Hi my friends, I feel that is very important to inform this list about my efforts and also receive an important feedback. We really feel that getting the things below to work on qemu will be an important step for LinuxBIOS, since people who do not have access to proper hardware will be able to test it and contribute in some ways. I haven't had success yet but this is what I got.
I am going to detail all the steps I've taken up to now. Preparing Images: 1- My first step create 2 qcow disk images, one for win2k(2G) and another one for winXP(3G), I followed these instructions:
http://www.hermann-uwe.de/blog/howto-install-windows-xp-in-debian-using-qemu 2- I installed a small version of Fedora in these images and of course grub in the MBR.
Preparing linuxbios: 1- My first step was to patch the as86 compiler. 2- Executed Makefile with make in the ADLO directory 3- Edited the payload option in the Config.lb file within qemu-i386 directory of LinuxBIOS to point to the payload generated by ADLO. 4- Run make and copied qemu-bios.rom to my home as bios.bin 5- Copied the vgabios-cirrus.bin to the same directory above. 6- Ran the following command : qemu -L ~ 2k_linux.cow -no-kqemu -serial stdio
With win2k got the following output: LinuxBIOS-2.0.0-OpenBIOS Wed May 2 19:21:12 BRT 2007 starting... Copying LinuxBIOS to RAM. Jumping to LinuxBIOS.

When I pressed some keyboard keys I got the following:

After I closer look I found out taht most of these problems were due to GRUB interupts.
PS: Both images work fine with: qemu 2k_linux.cow -no-kqemu -serial stdio
I appreciate any suggestion,
