<p class="MsoNormal">Hello again,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a need in my option ROM to interrogate devices identified by the BIOS PCI bus enumeration process. It seems like the most straight forward way to do this would be to use INT 1A assuming seaBios supports PCI 2.0 or later, to search
for all instances of devices which I’m interested in. Can anyone confirm whether seaBios supports PCI 2.0 or later? I see a hardcoded org at 0xfe6e in romlayout.S that appears to be the entry to that handler. I’ve tried using the INT instruction as well
as calling directly to 0xf000fe6e. Direct calls result in KVM crash as below. I suspect this is due to not using the proper 16/32 bit call interface. Using INT 1A I don’t appear to be going through this code at all.<o:p></o:p></p>
