After a little reading, it appears that there are actually 3 types of DVI cables... DVI-A (analog only), DVD-D (digital only) & DVD-I (carries parts of both I think?) .. in any case it seems that some LCD/video card combo's require either DVI-A or I to display the BIOS, but I think the workaround for you is to connect both VGA & DVI cables together & just switch inputs when you need to access the BIOS... either that or try to scare up a DVI-I cable.
