EtherJet, the interrupt is selected in the eeprom based on the layout of the PC Card board. Since this is encoded into the EEPROM, and has no relationship to the IRQ that the pccard bridge routes the PC Card's interrupt pin to. As such, stop writing to that register. This gets my EtherJet working. # The eeprom reading code appears to be totally wrong for my EtherJet # card. This causes the card to bogusly detect the media options # available.
