- When I first read about the other patch, I did try checking wd_alsts
- rather than wd_status. Not knowing didley about the disk controller,
- I'm not sure what the difference between these two registers are.
- But, being a shameless hacker, I tried it anyway. Alas, this was no
- help. It was at this point that I resorted to my ugly hack.
- It may be that the wrong register is checked. If so, then there is also
- another problem. I'm sure someone more knowledgeble than I will shed some light on this situation soon.

-
- Point well taken. In the future I will use full paths, in order to
- avoid confusion. This sounds like a policy that everyone should follow.
