 I have just verified this with the 7.0-CURRENT-200706-amd64-disc1.iso
 version and you are right. Can you try a i386 version please?
 I know this is not the right categorie (amd64 vs i386) but this was the
 only thread I found discussing FreeBSD on the HP dc5750.
 I don't think this is problem is related to i386 or am64. I think it's
 more related to the BIOS and the different ways FreeBSD, NetBSD and
 Linux are calling the BIOS.

 I can build the world and a CURRENT kernel on the machine as well as
 install and run them. The machine is also able to use our diskless boot
 environment with some minor extensions in /boot/beastie.4th.

 We can not get full control over the ATI SB600 HDA controller. There is
 no output on the rear plug and the internal speaker volume is the same
 as the front headphone plug. Linux distinguishes between internal speaker
 and headphone, but there is no output at the rear plug as well.

 USB mouse and keyboard are detected and functioning. But there is a
 problem with USB sticks. Depending on the manufacturer (I tried 3 different)
 the stick is never detected as umass(4) device or there will be umass
 I/O errors. In any case the operation system will slow down until it is
 almoust not responding to keyboard (PS2 or USB) activity.
