I have several machines set up here. I can set up an older asus p55tp4xe p133 64MB to bench the 2.1.7R with your driver, patch in the tekram stuff and bench that, patch your driver for ultra negotiations, and test + bench that. Please send your ultra patch if it isn't any trouble. I will be getting another 2 UW disks, and can use them to test with. It would be nice to have a big stack of disks to test the speeds from multiple UW, but .... :) Would it be helpful to test with ccd? del ... > > > I wanted to clean up some of the code before the > > > 20MHz speed is enabled, but was held back by some > > > other (higher priority) tasks ... > > > > Is it enabled by default?

I will use the stock 2.1.7R driver with my server, and set the seagate uw drive to 10mhz in the tekram setup. That should be ok for now. Yes, please send the diffs. I am going to use my other machine to stage the upgrade, and then do it on the server. I can run tests and bench- marks on the test machine while I am at it. > > I have half-way completed the cleanup of the code, > that deals with negotiation values.

I am a *stable* kind of guy. :) Thanks, -- Craig Shaver (craig@progroup.com) (415)390-0654 Productivity Group POB 60458 Sunnyvale, CA 94088
