OK, just looked a bit more closely at this, if the r_bmio address is not set in the chipset registers something is wrong as these are used to setup PIO and DMA timings in the chipset. So if your BIOS doesn't set the bmio address, there is *no way* I can set any modes on your HW, ie you need to use whatever mode the BIOS has setup for you. Could you please dump the pci reg 0x20 (with pciconf) and verify that it is endeed 0 ? -Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
