I had a compact flash card in my system and had to run out...the system did its thing and shut down an hour after I did not get back to it....
But now, (and I have been working on this all day)...the thing WILL NOT even get past BIOS(freezes up mid-bios) without the compact flash card in. If I take the compact flash out as Windows 7 is starting...it freezes as soon as you get to the ubiquitos "Pulsing Window"
I am sure (though I cannot find it in the bios menu or in MSCONFIG) that the boot order does NOT go USB first. ...and even if it did, it should pop to the next selection when the first does not send info...but alas, it does not...just sits there waiting for me to put the card back in and restart.
