Have you calibrated it? Hmm. I would also suggest you check to see if the device is being enabled on the PCI bus. That is is the pci command register is the pci master bit being set? Without this the card probably cannot do DMA. Which can cause all kinds of problems. I know I had to implemented this for the 3com adapter I use. Ken with these currticks would you have any problem if we moved the timer implementation completely into etherboot. That we don't get a weird case that can only be used under linuxBIOS. Eric |
