RK611 schematics

The subject line does not cover this reply, but I think it is good to keep the reply in this thread. I ran the 5 diagnostics (ZR6A - ZR6E) for the RK611 controller, and let each diagnostic run for 2 passes. They all reported no errors. So, time to connect the RK07 drive. Then I ran ZR6H, the first diagnostic for controller -and- a drive. After some 12 minutes I got a print out of the controller registers, (as I had before ...), but this time I looked a bit better at the data and went through the meaning of all bits. In RKCS1 bit 15 CERR was set, this is the Combined Error flag, and you must look at the other bits to find the reason. Then I found that the BSE, Bad Sector Error bit was set ...! I wondered "is the pack I'm using good?", and mounted an other pack. To cut a long story short: I am now booting the 11/34 from DM0: !!! Again, I learned a lot about the hardware, but more important: - do not assume the worst, the problem is often simple. - if the system gives you data, have a *very* good look at it. thanks, - Henk.
