- I think you should extent the standard hd.c with a driver for the secondary
- controller. I had a lokk at this and found that it should be possible
- to add code to handle the secondary with minor numbers from 128-255. But the
- problems is, what is with the interrupts form the secondary controller.
- I never had the time to try it, so i'm just waitung as you for a release which
- supports the secondary controller.
-
- The other problem is, since there are no entries in the cmos for the second
- drive you must hardcode the driveparameters in the kernel for all? drives.
