I took apart one of my WebDT GX 366s' and located some interesting points on the motherboard. HDD2 is actually a CF style set of pads under the main Compact Flash slot. There is not enough room to install an internal CF slot and put a card in it. This explains why there is a 'Boot from HDD2' option in the BIOS. There is a questionable switch on the motherboard. Its a SPDT switch, and wen set to the the non-default position I dont see any noticable boot order change. I was hoping it would bring the onboard CF card to live bridged over HDD2, but it didnt. One thing I did notice is that my right speaker was making a hissing noise as if it was picking up some EMF from something.
I will post detailed pics and information with my findings in a few days, please be patient.
