Thanks for the tip.

Unfortunately, the PowerEdge SC1435 BIOS does not allow much
options here ... I can set the embedded SATA to 'ATA mode'
(corruption hell, tested with 7.1 BETA) or just turn it
'OFF' in which case the FreeBSD installer sees no disk

This is on BIOS v1.1.2. A newer v1.4.4 is available and I'm
now researching how to update the BIOS to see if that helps.

I've used the amd64 version ... don't know if that makes any
difference, though.
