Subject: Use extended interrupt descriptor for pci irqs.
X-Git-Tag: rel-0.5.0~77
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=dff08dabebd460c3be0cef1a37ecbb6515c2aadb;p=seabios.git

Use extended interrupt descriptor for pci irqs.

This is necessary to allow freebsd to boot; freebsd chokes if a regular
interrupt descriptor specifies an active high pic irq.
