[Qemu-devel] Boot Failure

[Yang Zhang]

Hello,
    Hello,
   I'm a freshman to seabios. I'm working on developing  an OS with my 
teammates and using seabios to boot a virtual machine(Our OS -> seabios-> grub 
-> guest Linux) on our OS. We have a few  machines to test our OS,  However,  
seabios can't boot guest linux  on some machines while boot successfully on 
others. On the failure machine, I found a such error message:
                  "Booting from Hard Disk...
                   Error loading operating system" 
And I have glanced the source code of seabios and grub, but I can't find any 
code related to it.  I found that this problem may be related to the interrupt 
handler in seabios. Can anyone tell me where can I find the document about the 
seabios interrupt call? Thank you very much.
