If I comment the assignment to pci_using_dac, the compiler issues warnings, but it makes no visible difference to assign 1 or 0.
If I had real hardware what could I brake by playing with this code?
Does the following help: <URL:http://en.wikipedia.org/wiki/Conventional_PCI#Dual-cycle_address> On real hardware, when using a PCI bus, setting the PCIDAC flag in 8139cp.c is intended to signify that 64-bit addressing is being used. -- Gareth Davies, Lotwillow Ltd
