Ok, then add a couple printfs to the pci_read_vpd_reg line... one before the WREG line, and another before the return... I have a feeling that your card isn't setting the correct bit, as the printf you enabled w/ if 1 won't run unless it gets data from this function... If you're hanging in this function, then I'll have to do something else... :( or you could return the card/mobo as not PCI compliant... but I doubt you'd want to do the last one.. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Sat Nov 04 2006 - 19:14:23 UTC
