Hi, I'm looking for comments on the following issue: I had problems getting the 5.1.4 driver (Linux 2.0.36) to work with my Syquest drive - I believe the little beast is blessed with buggy firmware. It will happily negotiate synchronous transfers with the host and then hang the bus. It will work under winlose if I disable sync negotiation for the drive in the adapter BIOS (2940UW), which is also what happens with the 5.1.0pre5 driver. I have hacked the 5.1.4 driver to force async transfers for a target if sync and wide negotiation are disabled in the BIOS, so the drive is currently working. What I would like to hear about is 1. Will there be a way to force async transfers in a future revision of the driver? or, if not 2. Will anybody familiar with the aic7xxx code have a look at my patch (which I consider to be a nasty hack) and make suggestions as to how this should be done properly? TIA -- H.J.
