I got a little further, but now there seems to be something wrong with the IRQ:On 06/06/2013 11:56 PM, Michael Schmitz wrote:Geert, other than 'it compiles', I can't really say much about this one. I've done what seemed necessary to do the ESP probe setup in the zorro driver framework (using the NCR7xx driver as a guideline), and used the old Blizzard 2060 driver as a model for the DMA setup. To adapt to another style of ESP integration, the DMA setup function will need to be changed. The simplest way to cater for multipe boards in this driver may be to provide a separate DMA setup function for each, and substitute the correct one for the default esp_ops field in the driver probe. Please correct me if you see a better or simpler way.Thank you for rewriting the driver.I copypasted the appropriate DMA code from blz1230.c, and added some code to switch to the appropriate function. I compiled the module, and was able to insert and remove it.The dmesg output is attached. I also attached the modified zorro_esp.c.There is a HDD attached to the SCSI bus, but the scan does not take place.The chip on the controller is a FAS216, but it is identified as a FAS236. Does that matter?
