SIlicon Image 3112 PCI SATA controller; connecting harddrives makes boot fail
I have a SiL3112 PCI SATA controller card that i have used in another computer for quite a while without any problems. Now I am trying to use it in this computer (Athlon 1GHz, 256Mb RAM). If I just plug it into a PCI slot and boot without any harddrives connected to it then everything goes fine, it's BIOS flashes up it's little message, and the computer boots from the main (PATA) harddrive. However if I plug a harddrive (Seagate Barracuda 200GB) into the card then the BIOS stops at 'varifying DMI data...' and doesn't even try to boot from the CD. I am very puzzeled by this as the card worked perfectly on the other computer, which was a similar machine.
