>Description:
The cd never starts the bootloader, it tries and you can see that it finds /boot/loader but after that it reboots. We have installed a lot of bsd machines at the place where i work so it's probably a machine problem but FreeBSD 3.2 and 4.11 worked fine on the machine so disabling ACPI in the BIOS was our first thought though that did not help at all. The machine is a dual intel xeon motherboard with two single core xeon cpus with hyperthreading, the parts are brand new and as i said before 3.2 and 4.11 worked fine just like windows worked fine on it. 5.3, 5.4 and 6.0 both show the problems.

Here are some specs on the motherboard.

Asus PC-DL Deluxe
CPU: Intel Xeon up to 3.06GHz On-die 512KB L2 cache
Chipset: Intel 82875P MCH; Intel 82801ER ICH5R
FSB: 533/400MHz
Memory: Dual-channel 4x184pin DDR DIMM up to 4GB PC2700/2100

I think thats all you need really. I should note that we tried downloading new images from more than one site, used already ready cds that had been used the days before the problem and checked md5 checksums.
>How-To-Repeat:
Boot a 5.3, 5.4 or 6.0 cd.
