There is a known problem with some BIOSes trying to enter protected mode when serving requests, esp. USB stacks. The usual simptom of the problem is BTX panic on the console. I cannot say for sure whether this is your case. The patch exists that modifies BTX to reflect interrupts and requests into the real mode, see http://people.freebsd.org/~kib/realbtx/ http://people.freebsd.org/~kib/realbtx/realbtx.2.patch You would need to either somehow inplant supplied loader into your CD image, or rebuild the whole installation CD with patch applied. Again, I cannot guarantee that the patch is relevant for your problem. --xsILJLaVOAbiPmXa Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQFHCoYuC3+MBN1Mb4gRAumSAJkBuky4AT6+gr6eMKEXMLJC8mcERACfeeR6 0a332efIhgJiEyRnJBP/OmM= =w6B+ -----END PGP SIGNATURE----- --xsILJLaVOAbiPmXa--
