 I have another weird problem as part of this. If I boot the 7.1-BETA2 =20=
 
 or 8.0 snapshot 200811 bootonly iso images and hit 6 to escape to the =20=
 
 prompt, I can type for about 1-3 seconds and the system freezes. No =20
 more characters can be input and this is consistent across all boots =20
 of the ISOs. When I move back to the 7.0-RELEASE ISO, both bootonly =20
 and disc1, they allow me to hit 6 to escape to the prompt and I can =20
 type as long as I like with no lockups whatsoever.
 
 On a 7.0-RELEASE CD, I hit 6 to get to the boot prompt and asked it =20
 for my settings. Here's what it has, manually typed by me. For this =20
 capture I had re-enabled serial, parallel, network, firewire, and USB =20=
 
 ports.

 More information from the Intel technical spec for this board:
 
 1.5.3.1 Serial ATA Support
 The ICH8=92s Serial ATA controller offers six independent Serial ATA =20
 ports with a
 theoretical maximum transfer rate of 3 Gbits/sec per port.  One device =20=
 
 can be installed
 on each port for a maximum of six Serial ATA devices.  A point-to-=20
 point interface is
 used for host to device connections, unlike Parallel ATA IDE which =20
 supports a
 master/slave configuration and two devices per channel.
 For compatibility, the underlying Serial ATA functionality is =20
 transparent to the
 operating system.  The Serial ATA controller can operate in both =20
 legacy and native
 modes.  In legacy mode, standard IDE I/O and IRQ resources are =20
 assigned (IRQ 14
 and 15).  In Native mode, standard PCI Conventional bus resource =20
 steering is used.
 Native mode is the preferred mode for configurations using the =20
 Windows* XP and
 Windows 2000 operating systems.
