Fatal Trap 10: trace trap while in vm86 mode, trying to boot install CD after menu

[Peter G]

For completeness sakes of the archives my solution
was:
to put the following in the /boot/loader.conf
it's the only way these machines will boot with
FreeBSD given their Serverworks chipsets. 

hw.hasbrokenint12=1
hw.ata.ata_dma=0 

If the previous is ommited after install (after the
CDROM is removed, we used a USB CDROM to load them
right on the racks) we'd get "Fatal Trap 12"

Curiosity question
All these blades have Serverworks chipset in them..
DO you recall if your gateways had that same chipset??

I am going to try when next i get a chance(at the
loader prompt):
set hw.hasbrokenint12=1
set hw.ata.ata_dma=0 

because thsi exchange in the archives leads me to
believe it's a chipset specific problem:

On these blades i am trying to install fr a USB CD
drive as the only options in the BiOS is boot fr USB
Floppy, USB CD, internal HD..
